Error codes and messages

When you make an API call to Adyen and there is an error, you will receive a response with HTTP status code different from 200. In this response, you get errorCode and message fields that help you diagnose and solve the error.

Depending on your integration type, there are a number of error codes you can receive. All integrations can receive Generic error codes.

There are also error codes specific for an integration type or payment method:

Generic error codes

000 - Unknown

This error can have multiple potential causes. Here are some examples:
Cause:

  • Validation 000: Lookup failed.
  • Unable to parse message.
  • Not Found.
  • paymentDetails not supplied: Check if the recurring details and the recurringDetailReference are being passed correctly.
  • Not allowed to change the shopperInteraction: The merchant recurring permission is missing.
  • The Account Updater connection is only supported for Visa & Mastercard.
  • CVC is required for OneClick card payments.

010 - Not allowed

Cause:

  • The web service user is missing the permissions API PCI role, HPP API Payments role, and/or API Payment RefundWithData role.
  • Incorrect user API.
  • In case of refundWithData, missing roles API Payment RefundWithData and Merchant Payout.

100 - Required object 'amount' is not provided.

101 - Invalid card number

Cause:

  • Incorrect card number or length.
  • Incorrect capitalization of PaRes.

  • Solution: URL-decode the PaRes and MD before submitting them in the /payments/details request.

  • Cause: The issuer returns the correct PaRes value, but the parameter name is different from PaRes, for example PaResponse or paRes.
  • Solution: Adyen only accepts this parameter as PaRes. If the issuer has returned something different, make sure that you change it to PaRes before submitting it in the /payments/details request.

  • Cause: The PaRes parameter is empty, or some other reason different from the above.
  • Solution: Ask your shopper to contact the issuing bank to report the error.

  • Internal Error.
  • Required field shopperEmail is 'null'.
  • Problem parsing request.

704 - Request already processed

Cause: The web service user is sending multiple authorised requests.
Solution: Check that you send in requests only once.

800 - Contract not found

Cause:

  • shopperReference does not exist.
  • The requestData is creating a contract and using the recurringDetailReference at the same time.

Solution: Check if the details were saved previously, check the shopperReference.

807 - Invalid combination of shopper interaction and recurring-contract

Cause: Recurring contract was not set up with shopperInteraction.

Cause:

14_003 - Invalid paymentData

14_004 - Missing payment method details

15_022 - invalid authenticationOnly field

15_023 - threeDS2RequestData is not supported for threeDS2InMDFlow
