Credentials

Revoke Credential

Permanently revoke an active credential. Flips status to INACTIVE, records inactiveAt and inactiveReason, and appends a signed REVOKE event to the credential’s chain. Optionally include a reason (max 200 chars) in the request body to record why the credential was revoked; it is stored as the credential inactiveReason, prefixed as revoked:<reason>, and included in the REVOKE event. Subsequent /vp and /verify calls for this credential are denied with reason credential_revoked (credential_inactive for an API version before 2026-11-02).

Headers

API-Version

string

Pin request, response, and webhook shapes to a specific dated API version (YYYY-MM-DD). Omit to use the version pinned to your API key (set when the key is created; new keys default to the latest version). New integrations should target the latest version.

Pattern: ^\d{4}-\d{2}-\d{2}$

Example:

"2026-11-02"

Path Parameters

credentialId

string

required

URN of the credential to revoke

Example:

"urn:via:credential:550e8400-e29b-41d4-a716-446655440000"

Body

application/json

reason

string

Free-text reason for revocation, recorded on the credential as inactiveReason, prefixed as revoked:<reason>. It is signed into the mandate's REVOKE event for good, so it says why, never who: no names, emails or other personal data (v0.3 §2). Recommended values from VIA protocol v0.2-new §5.5.1: "user_initiated", "organization_policy", "system_expiry".

Maximum string length: 200

Example:

"user_initiated"

Response

Credential revoked. The revocation is recorded as a REVOKE proof on the credential.

credentialId

string

required

URN of the revoked credential

Example:

"urn:via:credential:550e8400-e29b-41d4-a716-446655440000"

status

enum<string>

required

Always REVOKED on a successful response (v0.3 §0.10.1); the REVOKE event on its chain records it. An API version before 2026-11-02 receives INACTIVE.

Available options:

REVOKED

Example:

"REVOKED"

revokedAt

string

required

When the credential was revoked (ISO 8601)

Example:

"2026-05-02T10:15:30.000Z"
