MERCHANT_GET_ORDERS_ID_INVALID_CONTRACT_VERSION	2107	500 (INTERNAL_SERVER_ERROR)	The contract terms version is not understood by the merchant backend. Most likely the merchant backend was downgraded to a version incompatible with the content of the database.
MERCHANT_TAN_CHALLENGE_FAILED	2125	409 (CONFLICT)	The provided TAN code is invalid for this challenge.
MERCHANT_TAN_CHALLENGE_UNKNOWN	2126	404 (NOT_FOUND)	The backend is not aware of the specified MFA challenge.
MERCHANT_TAN_TOO_MANY_ATTEMPTS	2127	429 (TOO_MANY_REQUESTS)	There have been too many attempts to solve the challenge. A new TAN must be requested.
MERCHANT_TAN_MFA_HELPER_EXEC_FAILED	2128	502 (BAD_GATEWAY)	The backend failed to launch a helper process required for the multi-factor authentication step. The backend operator should check the logs and fix the Taler merchant backend configuration.
MERCHANT_TAN_CHALLENGE_SOLVED	2129	410 (GONE)	The challenge was already solved. Therefore, the service refuses to send it again.
MERCHANT_TAN_TOO_EARLY	2130	429 (TOO_MANY_REQUESTS)	It is too early to request another transmission of the challenge. The client should wait and see if they received the previous challenge.
MERCHANT_MFA_FORBIDDEN	2131	403 (FORBIDDEN)	There have been too many attempts to solve MFA. The client may attempt again in the future.
MERCHANT_TAN_ADDRESS_UNUSABLE	2132	400 (BAD_REQUEST)	The transmission helper rejected the address configured for this multi-factor authentication step: it is malformed, of the wrong length, not a mobile subscription, unallocated, or blocked. The address should be corrected.
MERCHANT_TAN_ADDRESS_UNREACHABLE	2133	503 (SERVICE_UNAVAILABLE)	The address is valid but the recipient could not be reached: the handset is switched off or out of coverage, or the message expired before delivery. Retrying later may succeed.
MERCHANT_TAN_HELPER_MISCONFIGURED	2134	500 (INTERNAL_SERVER_ERROR)	The transmission helper is misconfigured: a required credential is absent, the configured credentials were refused by the provider, or the provider account has insufficient balance. The backend operator should check the logs and fix the Taler merchant backend configuration.
MERCHANT_POST_ORDERS_ID_PAY_INSUFFICIENT_FUNDS	2150	409 (CONFLICT)	The exchange responded saying that funds were insufficient (for example, due to double-spending).

MERCHANT_POST_ORDERS_ID_PAY_INSUFFICIENT_DUE_TO_FEES	2155	400 (BAD_REQUEST)	After considering deposit and wire fees, the payment is insufficient to satisfy the required amount for the contract. The client should revisit the logic used to calculate fees it must cover.
MERCHANT_POST_ORDERS_ID_PAY_PAYMENT_INSUFFICIENT	2156	400 (BAD_REQUEST)	Even without considering deposit and wire fees, the payment is insufficient to satisfy the required amount for the contract.
MERCHANT_POST_ORDERS_ID_PAY_COIN_SIGNATURE_INVALID	2157	403 (FORBIDDEN)	The signature over the contract of one of the coins was invalid.
MERCHANT_POST_ORDERS_ID_PAY_EXCHANGE_LOOKUP_FAILED	2158	500 (INTERNAL_SERVER_ERROR)	The merchant backend failed to find information about the exchange to issue the deposit. This usually happens when the merchant backend’s HTTP client logic is not working.
MERCHANT_POST_ORDERS_ID_PAY_REFUND_DEADLINE_PAST_WIRE_TRANSFER_DEADLINE	2159	500 (INTERNAL_SERVER_ERROR)	The refund deadline in the contract is after the transfer deadline.

MERCHANT_POST_ORDERS_ID_PAY_MERCHANT_FIELD_MISSING	2162	500 (INTERNAL_SERVER_ERROR)	The merchant field is missing from the proposal data. This is an internal error because the proposal comes from the merchant’s own database at this point.

MERCHANT_POST_ORDERS_ID_PAY_EXCHANGE_WIRE_FEE_ADDITION_FAILED	2166	500 (INTERNAL_SERVER_ERROR)	The exchange of the deposited coin charges a wire fee that could not be added to the total (total amount too high).
MERCHANT_POST_ORDERS_ID_PAY_REFUNDED	2167	402 (PAYMENT_REQUIRED)	The contract was not fully paid because of refunds. Clients may treat it as paid if, for example, the contract must be executed despite refunds.
MERCHANT_POST_ORDERS_ID_PAY_REFUNDS_EXCEED_PAYMENTS	2168	500 (INTERNAL_SERVER_ERROR)	The database indicates that more was refunded than was paid, which should not be possible.
MERCHANT_PRIVATE_POST_REFUND_AFTER_WIRE_DEADLINE	2169	410 (GONE)	The refund request is too late because it is past the wire transfer deadline of the order. The merchant must find a different way to pay back the money to the customer.
MERCHANT_POST_ORDERS_ID_PAY_EXCHANGE_FAILED	2170	502 (BAD_GATEWAY)	The payment failed at the exchange.
MERCHANT_POST_ORDERS_ID_PAY_AGE_COMMITMENT_MISSING	2171	400 (BAD_REQUEST)	The payment required a minimum age but one of the coins (of a denomination with support for age restriction) did not provide any age_commitment.
MERCHANT_POST_ORDERS_ID_PAY_AGE_COMMITMENT_SIZE_MISMATCH	2172	400 (BAD_REQUEST)	The payment required a minimum age but one of the coins provided an age_commitment that contained a wrong number of public keys compared to the number of age groups defined in the denomination of the coin.
MERCHANT_POST_ORDERS_ID_PAY_AGE_VERIFICATION_FAILED	2173	400 (BAD_REQUEST)	The payment required a minimum age, but one of the coins provided a minimum_age_sig that could not be verified with the given age_commitment for that minimum age.
MERCHANT_POST_ORDERS_ID_PAY_AGE_COMMITMENT_HASH_MISSING	2174	400 (BAD_REQUEST)	The payment required no minimum age but one of the coins (of a denomination with support for age restriction) did not provide the required h_age_commitment.
MERCHANT_POST_ORDERS_ID_PAY_WIRE_METHOD_UNSUPPORTED	2175	409 (CONFLICT)	The exchange does not support the selected bank account of the merchant. Likely the merchant had stale data on the bank accounts of the exchange and thus selected an inappropriate exchange when making the offer.
MERCHANT_POST_ORDERS_ID_PAY_CHOICE_INDEX_MISSING	2176	400 (BAD_REQUEST)	The payment requires the wallet to select a choice from the choices array and pass it in the ‘choice_index’ field of the request.
MERCHANT_POST_ORDERS_ID_PAY_CHOICE_INDEX_OUT_OF_BOUNDS	2177	400 (BAD_REQUEST)	The ‘choice_index’ field is invalid.

MERCHANT_POST_ORDERS_ID_PAY_EXCHANGE_TRANSACTION_LIMIT_VIOLATION	2184	400 (BAD_REQUEST)	The payment violates a transaction limit configured at the given exchange. The wallet failed to check exchange limits during coin selection. The wallet developer should investigate.
MERCHANT_POST_ORDERS_ID_PAY_DONATION_AMOUNT_MISMATCH	2185	409 (CONFLICT)	The donation amount provided in the BKPS does not match the amount of the order choice.
MERCHANT_POST_ORDERS_ID_PAY_EXCHANGE_LEGALLY_REFUSED	2186	451 (UNAVAILABLE_FOR_LEGAL_REASONS)	Some of the exchanges involved refused the request for reasons related to legitimization. The wallet should try with coins of different exchanges. The merchant should check if they have some legitimization process pending at the exchange.
MERCHANT_POST_ORDERS_ID_PAY_CHOICE_INDEX_MISMATCH	2187	409 (CONFLICT)	The order was already paid, but the request specified a different choice. The client should use the choice with which the order was actually paid.

MERCHANT_POST_ORDERS_ID_ABORT_REFUND_REFUSED_PAYMENT_COMPLETE	2254	412 (PRECONDITION_FAILED)	The payment was already completed and thus cannot be aborted anymore.
MERCHANT_POST_ORDERS_ID_ABORT_CONTRACT_HASH_MISSMATCH	2255	403 (FORBIDDEN)	The hash provided by the wallet does not match the order.
MERCHANT_POST_ORDERS_ID_ABORT_COINS_ARRAY_EMPTY	2256	400 (BAD_REQUEST)	The array of coins cannot be empty.

MERCHANT_POST_ACCOUNTS_KYCAUTH_BANK_GATEWAY_UNREACHABLE	2275	502 (BAD_GATEWAY)	The merchant backend failed to reach the banking gateway to shorten the wire transfer subject. This probably means that the banking gateway of the exchange is currently down. Contact the exchange operator or simply retry again later.
MERCHANT_POST_ACCOUNTS_EXCHANGE_TOO_OLD	2276	502 (BAD_GATEWAY)	The merchant backend failed to reach the banking gateway to shorten the wire transfer subject. This probably means that the banking gateway of the exchange is currently down. Contact the exchange operator or simply retry again later.
MERCHANT_POST_ACCOUNTS_KYCAUTH_EXCHANGE_UNREACHABLE	2277	502 (BAD_GATEWAY)	The merchant backend failed to reach the specified exchange. This probably means that the exchange is currently down. Contact the exchange operator or simply retry again later.
MERCHANT_POST_ORDERS_ID_CLAIM_NOT_FOUND	2300	404 (NOT_FOUND)	The order could not be claimed because the backend is unaware of it.
MERCHANT_POST_ORDERS_ID_CLAIM_ALREADY_CLAIMED	2301	409 (CONFLICT)	The order could not be claimed because another client claimed it first.

MERCHANT_PRIVATE_POST_ORDERS_INSTANCE_CONFIGURATION_LACKS_WIRE	2500	404 (NOT_FOUND)	The merchant instance has no active bank accounts configured. However, at least one bank account must be available to create new orders.
MERCHANT_PRIVATE_POST_ORDERS_NO_LOCALTIME	2501	500 (INTERNAL_SERVER_ERROR)	The proposal had no timestamp and the merchant backend failed to obtain the current local time.
MERCHANT_PRIVATE_POST_ORDERS_PROPOSAL_PARSE_ERROR	2502	400 (BAD_REQUEST)	The order provided to the backend could not be parsed; likely some required fields were missing or ill-formed.

MERCHANT_PRIVATE_POST_ORDERS_REFUND_AFTER_WIRE_DEADLINE	2504	400 (BAD_REQUEST)	The order creation request is invalid because the given wire deadline is before the refund deadline.
MERCHANT_PRIVATE_POST_ORDERS_DELIVERY_DATE_IN_PAST	2505	400 (BAD_REQUEST)	The order creation request is invalid because the delivery date given is in the past.
MERCHANT_PRIVATE_POST_ORDERS_WIRE_DEADLINE_IS_NEVER	2506	400 (BAD_REQUEST)	The order creation request is invalid because a wire deadline of never is not allowed.
MERCHANT_PRIVATE_POST_ORDERS_PAY_DEADLINE_IN_PAST	2507	400 (BAD_REQUEST)	The order creation request is invalid because the given payment deadline is in the past.
MERCHANT_PRIVATE_POST_ORDERS_REFUND_DEADLINE_IN_PAST	2508	400 (BAD_REQUEST)	The order creation request is invalid because the given refund deadline is in the past.
MERCHANT_PRIVATE_POST_ORDERS_NO_EXCHANGES_FOR_WIRE_METHOD	2509	409 (CONFLICT)	The backend does not trust any exchange that would allow funds to be wired to a bank account of this instance using the wire method specified with the order. Exchange bank accounts with mandatory currency conversion are not currently supported. A likely cause is that the taler-merchant-exchangekeyupdate process is not running.
MERCHANT_PRIVATE_PATCH_ORDERS_ID_FORGET_PATH_SYNTAX_INCORRECT	2510	400 (BAD_REQUEST)	One of the paths to forget is malformed.
MERCHANT_PRIVATE_PATCH_ORDERS_ID_FORGET_PATH_NOT_FORGETTABLE	2511	409 (CONFLICT)	One of the paths to forget was not marked as forgettable.
MERCHANT_POST_ORDERS_ID_REFUND_EXCHANGE_TRANSACTION_LIMIT_VIOLATION	2512	451 (UNAVAILABLE_FOR_LEGAL_REASONS)	The refund amount would violate a refund transaction limit configured at the given exchange. The merchant should use another way to refund the customer and consult the exchange operator about the applicable regulations.
MERCHANT_PRIVATE_POST_ORDERS_AMOUNT_EXCEEDS_LEGAL_LIMITS	2513	451 (UNAVAILABLE_FOR_LEGAL_REASONS)	The total order amount exceeds the legal transaction limits of the available exchanges, so a customer could not legally make this payment. The merchant may increase its limits by completing legitimization checks with exchange operators.
MERCHANT_PRIVATE_POST_ORDERS_NO_EXCHANGE_FOR_CURRENCY	2514	409 (CONFLICT)	A currency specified to be paid in the contract is not supported by any exchange that this instance can currently use. Possible solutions include (1) specifying a different currency, (2) adding suitable exchange operators to the merchant backend configuration, or (3) satisfying the compliance rules of a configured exchange to begin using that provider’s service.
MERCHANT_PRIVATE_DELETE_ORDERS_AWAITING_PAYMENT	2520	409 (CONFLICT)	The order provided to the backend could not be deleted because the offer is still valid and awaiting payment. Deletion may work after the offer expires if it remains unpaid.
MERCHANT_PRIVATE_DELETE_ORDERS_ALREADY_PAID	2521	409 (CONFLICT)	The order provided to the backend could not be deleted as the order was already paid.
MERCHANT_PRIVATE_GET_STATISTICS_REPORT_GRANULARITY_UNAVAILABLE	2525	410 (GONE)	The client requested a report granularity that is not available at the backend. Possible solutions include extending the backend code and/or the database statistic triggers to support the desired data granularity. Alternatively, the client could request a different granularity.
MERCHANT_PRIVATE_POST_ORDERS_ID_REFUND_INCONSISTENT_AMOUNT	2530	409 (CONFLICT)	The requested cumulative Taler refund is inconsistent: it is lower than the amount already awarded, exceeds the amount paid through Taler, or would make the combined Taler and external refunds exceed the full order total.
MERCHANT_PRIVATE_POST_ORDERS_ID_REFUND_ORDER_UNPAID	2531	409 (CONFLICT)	Only paid orders can be refunded, and the frontend specified an unpaid order to issue a refund for.
MERCHANT_PRIVATE_POST_ORDERS_ID_REFUND_NOT_ALLOWED_BY_CONTRACT	2532	403 (FORBIDDEN)	The refund delay was set to 0 and thus no refunds are ever allowed for this order.
MERCHANT_PRIVATE_POST_ORDERS_TOKEN_FAMILY_SLUG_UNKNOWN	2533	404 (NOT_FOUND)	The token family slug provided in this order could not be found in the merchant database.
MERCHANT_PRIVATE_POST_ORDERS_TOKEN_FAMILY_NOT_VALID	2534	409 (CONFLICT)	A token family referenced in this order is either expired or not valid yet.
MERCHANT_PRIVATE_POST_ORDERS_ID_COLLECT_NOT_FREE	2535	409 (CONFLICT)	The order cannot be collected by the backend as it is not a genuinely free Taler payment: the Taler amount is not zero, or the selected choice has token inputs or outputs and thus requires a customer wallet.
MERCHANT_PRIVATE_POST_ORDERS_ID_COLLECT_ALREADY_CLAIMED	2536	409 (CONFLICT)	The order cannot be collected by the backend as it was already claimed by a customer wallet. The wallet owns the order and must execute the free payment itself.
MERCHANT_PRIVATE_DELETE_ORDERS_EXTERNALLY_PAID	2537	409 (CONFLICT)	The order provided to the backend could not be deleted as it has payments that were settled outside of Taler. Deletion requires an explicit force operation.
MERCHANT_PRIVATE_POST_ORDERS_ID_REFUND_EXTERNAL_INCONSISTENT_AMOUNT	2538	409 (CONFLICT)	The external refund could not be recorded as the cumulative externally refunded amount would exceed the full order total minus the amount already refunded through Taler.

MERCHANT_PRIVATE_POST_TRANSFERS_CONFLICTING_REPORTS	2553	409 (CONFLICT)	The exchange gave conflicting information about a coin which has been wire transferred.
MERCHANT_PRIVATE_POST_TRANSFERS_BAD_WIRE_FEE	2554	502 (BAD_GATEWAY)	The exchange charged a different wire fee than what it originally advertised, and it is higher.
MERCHANT_PRIVATE_POST_TRANSFERS_ACCOUNT_NOT_FOUND	2555	404 (NOT_FOUND)	The backend did not find the account to which the transfer was made.
MERCHANT_PRIVATE_DELETE_TRANSFERS_ALREADY_CONFIRMED	2556	409 (CONFLICT)	The backend could not delete the transfer because the exchange already responded to the inquiry and the result was integrated.
MERCHANT_PRIVATE_POST_TRANSFERS_CONFLICTING_SUBMISSION	2557	409 (CONFLICT)	The backend could not persist the wire transfer due to the state of the backend. This usually means that a wire transfer with the same wire transfer subject but a different amount was previously submitted to the backend.
MERCHANT_EXCHANGE_TRANSFERS_TARGET_ACCOUNT_UNKNOWN	2558	0 (UNINITIALIZED)	The target bank account given by the exchange is not (or no longer) known at the merchant instance.

MERCHANT_PRIVATE_POST_INSTANCES_BAD_AUTH	2601	400 (BAD_REQUEST)	The merchant backend cannot create an instance because the authentication configuration field is malformed.
MERCHANT_PRIVATE_POST_INSTANCE_AUTH_BAD_AUTH	2602	400 (BAD_REQUEST)	The merchant backend cannot update an instance’s authentication settings because the provided authentication settings are malformed.
MERCHANT_PRIVATE_POST_INSTANCES_PURGE_REQUIRED	2603	409 (CONFLICT)	The merchant backend cannot create an instance under the given identifier, the previous one was deleted but must be purged first.
MERCHANT_PRIVATE_POST_INSTANCE_AUTH_BAD_OLD_PASSWORD	2604	401 (UNAUTHORIZED)	The merchant backend cannot update an instance’s authentication settings because the required current password was missing or did not match.
MERCHANT_PRIVATE_PATCH_INSTANCES_PURGE_REQUIRED	2625	409 (CONFLICT)	The merchant backend cannot update an instance under the given identifier, the previous one was deleted but must be purged first.
MERCHANT_PRIVATE_ACCOUNT_DELETE_UNKNOWN_ACCOUNT	2626	404 (NOT_FOUND)	The bank account referenced in the requested operation was not found.

The exchange either does not support the wire method or does not support another property of the account. Check the exchange account constraints and specify a different bank account if necessary.
MERCHANT_PRIVATE_POST_PRODUCTS_CONFLICT_PRODUCT_EXISTS	2650	409 (CONFLICT)	The product ID exists.
MERCHANT_PRIVATE_POST_CATEGORIES_CONFLICT_CATEGORY_EXISTS	2651	409 (CONFLICT)	A category with the same name exists already.
MERCHANT_PRIVATE_PATCH_PRODUCTS_TOTAL_LOST_REDUCED	2660	409 (CONFLICT)	The update would have reduced the total amount of product lost, which is not allowed.
MERCHANT_PRIVATE_PATCH_PRODUCTS_TOTAL_LOST_EXCEEDS_STOCKS	2661	400 (BAD_REQUEST)	The update would have mean that more stocks were lost than what remains from total inventory after sales, which is not allowed.
MERCHANT_PRIVATE_PATCH_PRODUCTS_TOTAL_STOCKED_REDUCED	2662	409 (CONFLICT)	The update would have reduced the total amount of product in stock, which is not allowed.
MERCHANT_PRIVATE_PATCH_PRODUCTS_TOTAL_SOLD_REDUCED	2663	409 (CONFLICT)	The update would have reduced the total amount of product sold, which is not allowed.
MERCHANT_PRIVATE_POST_PRODUCTS_LOCK_INSUFFICIENT_STOCKS	2670	410 (GONE)	The lock request is for more products than we have left (unlocked) in stock.
MERCHANT_PRIVATE_DELETE_PRODUCTS_CONFLICTING_LOCK	2680	409 (CONFLICT)	The deletion request is for a locked product. The product cannot be deleted until the existing offer expires.
MERCHANT_PRIVATE_PRODUCT_GROUP_CONFLICTING_NAME	2690	409 (CONFLICT)	The proposed name for the product group is already in use. The client should select a different name.
MERCHANT_PRIVATE_MONEY_POT_CONFLICTING_NAME	2691	409 (CONFLICT)	The proposed name for the money pot is already in use. The client should select a different name.
MERCHANT_PRIVATE_MONEY_POT_CONFLICTING_TOTAL	2692	409 (CONFLICT)	The total amount in the money pot is different from the amount required by the request. The client should fetch the current pot total and retry with the latest amount to succeed.

MERCHANT_PRIVATE_POST_REWARD_AUTHORIZE_RESERVE_EXPIRED	2750	410 (GONE)	The reserve that was used to fund the rewards has expired.
MERCHANT_PRIVATE_POST_REWARD_AUTHORIZE_RESERVE_UNKNOWN	2751	503 (SERVICE_UNAVAILABLE)	The reserve that was used to fund the rewards was not found in the DB.
MERCHANT_PRIVATE_POST_REWARD_AUTHORIZE_INSUFFICIENT_FUNDS	2752	0 (UNINITIALIZED)	The backend knows the instance that was supposed to support the reward, and it was configured for rewardping. However, the funds remaining are insufficient to cover the reward, and the merchant should top up the reserve.
MERCHANT_PRIVATE_POST_REWARD_AUTHORIZE_RESERVE_NOT_FOUND	2753	503 (SERVICE_UNAVAILABLE)	The backend failed to find a reserve needed to authorize the reward.
MERCHANT_PRIVATE_GET_ORDERS_ID_AMOUNT_ARITHMETIC_FAILURE	2800	200 (OK)	The merchant backend encountered a failure in computing the deposit total.

MERCHANT_POST_USING_TEMPLATES_WRONG_TYPE	2864	409 (CONFLICT)	The selected template has a different type from the one specified in the client request. This may happen if the template was updated since the client last fetched it. The client should refetch the current template and send a request with the correct type.
MERCHANT_POST_USING_TEMPLATES_WRONG_PRODUCT	2865	409 (CONFLICT)	The selected template does not allow one of the specified products to be included in the order. This may happen if the template was updated since the client last fetched it. The client should refetch the current template and send a request with the correct type.

CHALLENGER_TOO_MANY_ATTEMPTS	9757	429 (TOO_MANY_REQUESTS)	Too many attempts have been made, validation is temporarily disabled for this address.
CHALLENGER_INVALID_PIN	9758	403 (FORBIDDEN)	The TAN code provided is incorrect.
CHALLENGER_MISSING_ADDRESS	9759	409 (CONFLICT)	Deprecated since protocol v8, no longer returned by any endpoint; see CHALLENGER_NO_CHALLENGE_TRANSMITTED. The value stays reserved and must not be reused. Was: the token cannot be valid as no address was ever provided by the client.
CHALLENGER_CLIENT_FORBIDDEN_READ_ONLY	9760	403 (FORBIDDEN)	The client is not allowed to change the address being validated.
CHALLENGER_NO_CHALLENGE_TRANSMITTED	9761	409 (CONFLICT)	No challenge was ever transmitted for this validation, so it cannot be solved yet. The user must provide their address first.
CHALLENGER_ADDRESS_RESTRICTION_VIOLATED	9762	400 (BAD_REQUEST)	An address field does not match the regular expression configured for it. The detail names the offending field.
CHALLENGER_ADDRESS_RESTRICTION_MALFORMED	9763	500 (INTERNAL_SERVER_ERROR)	The address restriction configured for this field is missing its regular expression or the expression failed to compile. This is a server misconfiguration.

CHALLENGER_ADDRESS_UNUSABLE	9769	400 (BAD_REQUEST)	The transmission helper rejected the address the user provided: it is malformed, of the wrong length, not a mobile subscription, unallocated, or blocked. The user should correct the address and try again.
CHALLENGER_ADDRESS_UNREACHABLE	9770	503 (SERVICE_UNAVAILABLE)	The address is valid but the recipient could not be reached: the handset is switched off or out of coverage, or the message expired before delivery. Retrying later may succeed.
CHALLENGER_HELPER_MISCONFIGURED	9771	500 (INTERNAL_SERVER_ERROR)	The transmission helper is misconfigured: a required credential is absent, the configured credentials were refused by the provider, or the provider account has insufficient balance. The operator should check the logs and the service configuration.
PAIVANA_PAYMENT_MISSING	9800	409 (CONFLICT)	The request is invalid as the specified order is unpaid. The client should only call this endpoint after paying the order.
PAIVANA_BACKEND_REFUSED	9801	502 (BAD_GATEWAY)	The merchant backend refused the request to check the payment status. The backend is either unavailable or Paivana is misconfigured. The system administrator should check the logs.

PAIVANA_BACKEND_ERROR	9803	500 (INTERNAL_SERVER_ERROR)	The merchant backend returned an unexpected status code. This is probably a protocol incompatibility that should be reported to the developers.
PAIVANA_GET_ORDER_FAILED	9804	500 (INTERNAL_SERVER_ERROR)	Paivana failed to initialize the request to check the payment status. This should never happen. The system administrator should consult the logs.
PAIVANA_WRONG_ORDER	9805	409 (CONFLICT)	The specified order does not match the specified Website or nonce and thus the order is invalid for the given request. Clients should pay for the correct order for access to the resource.
PAIVANA_TOO_LATE	9806	410 (GONE)	The specified expiration time for the cookie is longer than what the purchase allows. The request may succeed with a shorter expiration time. Alternatively, the user may need to purchase access again.
PAIVANA_TEMPLATE_UNKNOWN	9807	404 (NOT_FOUND)	The payment template specified in the request is unknown to the backend.
PAIVANA_PAYWALL_DISABLED	9808	501 (NOT_IMPLEMENTED)	The paywall functionality is currently disabled. Thus, proofs of payment are unnecessary and also not supported.
PAIVANA_INVALID_TARGET	9809	409 (CONFLICT)	The website specified in the request is not acceptable for this backend. Somehow the client must have specified an invalid website which is not configured for this Paivana reverse proxy and thus not eligible as a target for the redirect. A developer should check how the client computed the fulfillment_url of the order and fix it.
END	9999	0 (UNINITIALIZED)	End of error code range.
