Callback events

The Truvity EUDIW Connector delivers a Presented Credentials Event to your callback endpoint at the end of each presentation flow. The status field indicates the outcome.

Event statuses

Status	Description
FULFILLED	Verification succeeded and credentials are available in the event payload
REJECTED	The wallet declined the presentation request
EXPIRED	The session expired before the wallet responded
PROCESSING_ERROR	Internal processing failure (decryption, state validation)
VERIFICATION_FAILED	Credential verification failed (invalid signatures, revoked credentials, DCQL mismatch)

Payload fields by status

The event payload contains different fields depending on the status value.

Field	FULFILLED	REJECTED	EXPIRED	PROCESSING_ERROR	VERIFICATION_FAILED
state	Always	Always	Always	Always	Always
credentials	Present	Absent	Absent	Absent	Absent
credentialsRaw	Present	Absent	Absent	Absent	Absent
errorDetails	Absent	Present	Absent	Present	Present
responseCode	Same-device only	Absent	Absent	Absent	Absent

errorDetails field

The errorDetails field provides context for non-success statuses.

Status	errorDetails contents
REJECTED	The wallet's OAuth 2.0 error code and optional description (for example, access_denied or access_denied: User canceled)
PROCESSING_ERROR	A human-readable description of the internal error (for example, decryption errors or state validation failures)
VERIFICATION_FAILED	Credential verification failure details (for example, invalid signatures, revoked credentials, or DCQL mismatches)

responseCode field

For same-device flows, the event includes a responseCode field. The wallet redirects the user's browser back to your app with this code as a query parameter, allowing you to correlate the browser redirect with the callback event.
