Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

credentials*array<string>

This array includes a list of identifiers for mDocs credential configurations that will be included in the credential offer. These identifiers are the id elements returned in the response when you create a credential configuration. Providing the identifier of a non-mDocs credential configuration will result in an error.

userId?string

Unique system generated identifier to reference the user for this offer. This can be obtained by searching for a user. If not provided, a new user entity will be created.

transactionCodeConfiguration?

Configure whether a second-factor transaction code is required for this offer. If a configuration is provided, a code will be generated for the offer, and the end user must submit it during credential retrieval. If an incorrect transaction code is entered three times by the holder, the credential offer is permanently invalidated and the wallet can no longer claim the credential.

claims?object

Additional user claims that are available during credential issuance for this offer.

claimsToPersist?array<string>

This array includes a list of claims that will be persisted against the user object in the MATTR VII database. These claims are then available for any future credential offers or issuance operations for this user. By default no claims are persisted, and it is recommended to consider carefully which claims to persist, if any, as this has implications for data privacy and security.

expiresIn?

Specifies when the offer will expire. Once the offer expires, the user can no longer use it to claim a credential, and a new offer must be generated. The expiration period can include any combination of minutes and seconds. By default, the offer expires in 5 minutes, and the maximum allowed duration is 10 minutes.

In: header

Header Parameters

DPoP?string

DPoP proof JWT. A signed JWT that demonstrates proof-of-possession of a private key.

DPoP is offered as a closed beta preview feature and is not generally available yet. If you are interested in trying this feature, please contact us

When to use:

Token endpoint: Required when dpop_jkt was provided in the authorization request
Credential endpoint: Required when using DPoP-bound access tokens (Authorization header must use format: Authorization: DPoP <access_token>)

The DPoP proof must be a signed JWT with the following structure:

Header:

alg: Must be ES256
typ: Must be dpop+jwt
jwk: Public key (JWK format)

Payload:

htu: HTTP URI of the target endpoint
htm: HTTP method (e.g., POST)
jti: Unique identifier for this DPoP proof
iat: Unix timestamp when the DPoP proof was created
ath: Optional base64url-encoded SHA-256 hash of the access_token. Required when authenticating with the resource server.
htcd: Optional base64-encoded SHA-256 hash (content digest) of the HTTP request payload used to validate integrity.

Each DPoP proof must be unique and cannot be reused across requests.
