Error Codes from Account Aggregator

The following error codes are returned by the Account Aggregator to your FIU when the user is redirected back to your application. These codes help you understand what happened during the user’s consent journey on the AA platform.

Mandatory Error Codes

These error codes will always be returned in appropriate scenarios:

Error Code	Message	Status	Description
`0`	Success	S	The user has successfully accepted the consent request and linked their accounts
`1`	Consent is rejected	F	The user explicitly rejected the consent request on the AA platform
`2`	Consent not available	F	The consent request was not found on the Account Aggregator platform
`3`	Invalid request	F	The redirection request contained invalid or malformed data

Optional Error Codes

These error codes provide detailed information about specific failure scenarios:

Authentication and Session Errors

Error Code	Message	Status	Description
`4`	User authentication failed	F	The user was unable to authenticate themselves on the AA platform (e.g., wrong credentials, failed OTP)
`6`	Session timeout	F	The user did not take any action on the login page and the session expired

Account Discovery Errors

Error Code	Message	Status	Description
`7`	Account not discovered	F	A specific FIP ID was provided but accounts were not found at that FIP (404 error), and the user cancelled or went back from the AA page
`8`	Account not discovered	F	A specific FIP ID was provided but account discovery failed due to an error at the FIP (non-404 error), and the user cancelled or went back
`9`	Account not discovered	F	Multiple FIP IDs were provided (or none), and no accounts were discovered at any FIP due to errors or missing accounts

Account Linking Errors

Error Code	Message	Status	Description
`10`	Account not linked	F	Accounts were successfully discovered, but the user did not link any accounts and the session timed out
`11`	Account not linked	F	Accounts were successfully discovered, but the user chose to cancel instead of linking any accounts

Error Code	Message	Status	Description
`12`	Account link OTP not attempted	F	Accounts were discovered and the user clicked the link button, but did not enter the OTP and then cancelled the process
`13`	Account link OTP not attempted	F	Accounts were discovered and the user clicked the link button, but did not enter the OTP and the session timed out
`14`	OTP authentication failed	F	All account linking attempts failed because the user entered incorrect OTPs, and then cancelled the process
`15`	OTP authentication failed	F	All account linking attempts failed because the user entered incorrect OTPs, and the session timed out
`16`	Account link failed	F	The user entered a valid OTP, but all account linking attempts failed at the FIP level due to system errors

Partial Success/Failure Errors

These errors occur when dealing with multiple FIPs:

Error Code	Message	Status	Description
`17`	OTP failed (some accounts)	F	Multiple FIPs were involved; some account linking attempts failed due to incorrect OTPs, and the user cancelled
`18`	OTP failed (some accounts)	F	Multiple FIPs were involved; some account linking attempts failed due to incorrect OTPs, and the session timed out
`19`	Account link failed (partial)	F	Multiple FIPs were involved; some account linking attempts failed at the FIP level, and the user cancelled

General Error

Error Code	Message	Status	Description
`20`	Unknown error	F	The Account Aggregator was unable to send any valid error code due to an unexpected system error

Usage Notes

Handle All Error Codes: Implement proper error handling for all error codes in your application. The mandatory error codes (0-3) will always be returned, while optional codes (4-20) provide granular details about specific failure scenarios.
Success Status: A status of S and errorcode of 0 indicates successful consent approval and account linking. In this case, you can proceed to fetch financial data using the consent.
Failure Status: A status of F indicates that the consent was not successfully approved. Use the errorcode to determine the specific reason for failure and provide appropriate feedback to the user.
User Communication: Based on the error code, provide clear and actionable feedback to users. For example:
- Error code 1: Inform the user they rejected the consent and offer to retry
- Error codes 7-9: Suggest checking if the user has accounts at the specified FIP
- Error codes 12-15: Guide the user on OTP verification process
- Error code 20: Display a generic error message and suggest contacting support
Transaction Correlation: Use the txnid field to correlate the decrypted response with your original consent request. This is especially important in high-traffic applications where multiple consent flows may be in progress simultaneously.
VUA Storage: Store the userid (VUA) securely in your system as it uniquely identifies the user within the Account Aggregator ecosystem. You’ll need this for future consent requests and data fetching operations.
Security Considerations:
- Always validate the resdate to ensure the response is recent and not a replay attack
- Verify that the decrypted srcref matches your original consent handle
- Process the decrypted response immediately and do not store the encrypted ecres for extended periods
Partial Success Handling: Error codes 17-19 indicate partial success scenarios where some accounts were linked successfully. Consider implementing logic to handle these cases gracefully, allowing users to proceed with linked accounts or retry failed ones.
