The APIs defined here establish a blueprint for how the Building Block will interact with other Building Blocks. Additional APIs may be implemented by the Building Block, but the listed APIs define a minimal set of functionality that should be provided by any implementation of this Building Block.
In common for all services of the Identity Building Block, the API expects the calling Partner has been already authenticated and authorized to access the service. For detailed specifications of APIs with input/output formats please refer to API specifications defined in YAML in the corresponding GitHub repository.
The GovStack non-functional requirements document provides additional information on how 'adaptors' may be used to translate an existing API to the patterns described here. This section also provides guidance on how candidate products are tested and how GovStack validates a product's API against the API specifications defined here.
The tests for the Identity Building Block can be found in this GitHub repository.
The microservice interfaces are defined as per OPENAPI Ver3.0 standards.
For implementation purposes, it is suggested to refer TMF630_REST_API_Design_Guidelines.
The Identity usage APIs are a set of OpenAPI specifications exposed by the Identity Building Block to other building blocks and applications for user verification.
The Identity usage APIs are based on the following principles:
Verification APIs are inspired by OpenID Connect protocol which simplifies integrations using pre-existing libraries
Only secure options in OpenID connect should be supported to ensure the user data is handled securely
All biometric capture for user verification should be done using Secure Biometrics Interface standards
For Identity Building Block implementations that support mobile wallet integration, the following API spec should also be implemented.
Detailed API schemas written in YAML that define REST API endpoints for each of the services mentioned above are available on GitHub located at the Identity-Provider YAML.
The GovStack non-functional requirements document provides additional information on how 'adaptors' may be used to translate an existing API to the patterns described here.
The Enrollment APIs are a set of OpenAPI specifications exposed by the Identity Building Block ‘Enrollment Server’ service to any enrollment client.
The Enrollment APIs are based on the following principles:
When enrollment is done in one step, the CreateEnrollment can contain all the data and an additional flag (finalize) to indicate all data was collected.
During the process, the enrollment structure can be updated. Only the data that changed need to be transferred. Data not included is left unchanged on the server. In the following example, the biographic data is not changed.
Images can be passed by value or reference.
Existing standards are used whenever possible, for instance, the preferred image format for biometric data is ISO-19794. The underlying data should be of open mime types that offer good compression without loss of data (for example JPEG2000 for images).
These Credential Management APIs are a set of OpenAPI specifications exposed by the Identity Building Block to service identity credential requests by credential partners such as printing and QR code partners.
The Credential Management APIs are based on the following principles:
The credential request API is asynchronous for the identity holder i.e., the call to share credentials is responded with an event ID. Then the identity holder later uses the event ID to retrieve the details using the API '/events/{eventId}'.
The '/share-credential' API is used to convey the format of the credential information. The format allows the credential information to be masked/unmasked. The API also conveys the consent of the identity holder.
The API '/download/personalized-card' is used to download the identity card in PDF format.
Systems for Voter ID, Tax ID, Card printing etc. receive internal notifications from IDBB.
Wallet applications will receive the identity credentials as per pre-authorized flow.
The APIs '/block', '/unblock' and '/updateIdentity' can only be called by systems with administrative permissions given by the IDBB.
The Subscription Management APIs follow the APIs from these standards - WebSub and WebHooks.
This Services APIs is not yet specified, but it should be the purpose of a next iteration of the Identity Building Block Specification.
API to add new open ID connect (OIDC) clients, it can be invoked by other modules which manages the relying parties / partners.
Each relying party can associate to one or multiple OIDC client Ids.
On create, OIDC client status will be by default set to "active".
/client-mgmt/oidc-client
Current date and time when the request is sent
API to update existing Open ID Connect (OIDC) client, it can be invoked by other modules which manages the relying parties / partners when there any updates on the fields accepted in this API.
Authentication and authorization is based on a valid JWT issued by a trusted IAM system including "update_oidc_client" scope.
/client-mgmt/oidc-client/{client_id}
Client Identifier
785b806d0e594657b05aabdb30fff8a4
Current date and time when the request is sent
This is the authorize endpoint of Open ID Connect (OIDC). The relying party applications will do a browser redirect to this endpoint with all required details passed as query parameters.
This endpoint will respond with a HTML page / JS application to be loaded in the browser.
All the validations on the query parameter values will be performed, in case of any failures respective error message will be sent along with browser redirection back to relying party application.
/authorize
Specifies what access privileges are being requested for Access Tokens. The scopes associated with Access Tokens determine what resources will be available when they are used to access OAuth 2.0 protected endpoints. OpenID Connect requests MUST contain the OpenID scope value.

The value set here determines the authorization processing flow. To use the Authorization Code Flow, the value should be configured to "code".
code
Valid OAuth 2.0 Client Identifier in the Authorization Server.
Redirection URI to which the response would be sent. This URI must match one of the redirection URI values during the client ID creation.
Opaque value used to maintain state between the request and the callback. Typically, Cross-Site Request Forgery (CSRF, XSRF) mitigation is done by cryptographically binding the value of this parameter with a browser cookie.
String value used to associate a Client session with an ID Token, and to mitigate replay attacks. The value is passed through unmodified from the Authentication Request to the ID Token.
ASCII string value that specifies how the Authorization Server displays the authentication and consent user interface pages to the end user.

, popup
, touch
, wap
Space delimited case-sensitive list of ASCII string values that specifies whether the Authorization Server prompts the End-User for re-authentication and consent.

Maximum Authentication Age. This specifies the allowable elapsed time in seconds since the last time the end user was actively authenticated by the OP. If the elapsed time is greater than this value, then the OP MUST attempt to actively re-authenticate the end user. The max_age request parameter corresponds to the OpenID 2.0 PAPE [OpenID.PAPE] max_auth_age request parameter. When max_age is used, the ID Token returned MUST include an auth_time claim value.
End user's preferred languages and scripts for the user interface, represented as a space-separated list of BCP47 [RFC5646] language tag values, ordered by preference. For instance, the value "fr-CA fr en" represents a preference for French as spoken in Canada, then French (without a region designation), followed by English (without a region designation). An error SHOULD NOT result if some or all of the requested locales are not supported by the OpenID Provider.
Requested Authentication Context Class Reference values. Space-separated string that specifies the acr values that the Authorization Server is being requested to use for processing this Authentication Request, with the values appearing in order of preference. The Authentication Context Class satisfied by the authentication performed is returned as the acr Claim Value, as specified in Section 2. The acr Claim is requested as a Voluntary Claim by this parameter.

End-User's preferred languages and scripts for Claims being returned, represented as a space-separated list of BCP47 [RFC5646] language tag values, ordered by preference. An error SHOULD NOT result if some or all of the requested locales are not supported by the OpenID Provider.
This parameter is used to request specific claims to be returned. The value is a JSON object listing the requested claims. The claims parameter value is represented in an OAuth 2.0 request as UTF-8 encoded JSON.
No body
Once the client / relying party application receives the authorization code through redirect, this OIDC complaint endpoint will be called from the relying party backend application to get the ID Token and Access Token.
The JWT MUST contain the following REQUIRED Claim Values and MAY contain few additional OPTIONAL Claim Values:
iss<span style="color:#FF0000">*</span> (Issuer): This MUST contain the client_id of the OIDC / OAuth Client.
sub<span style="color:#FF0000">*</span> (Subject): This MUST contain the client_id of the OIDC / OAuth Client.
aud<span style="color:#FF0000">*</span> (Audience): Value that identifies the IDBB server as an intended audience. The IDBB server MUST verify that it is an intended audience for the token. The audience SHOULD be the URL of the IDBB's token endpoint.
exp<span style="color:#FF0000">*</span> (Expiration): Time on or after which the ID token MUST NOT be accepted for processing.
iat<span style="color:#FF0000">*</span>: Time at which the JWT was issued.</p>
Note: The Client Assertion JWT can contain other Claims. Any Claims used that are not understood WILL be ignored.</p>

Once the access token is received via the token endpoint, relying party backend application can call this OIDC compliant endpoint to request for the user claims.
Consented user claims will be returned as a JWT. This JWT will be a nested JWT which is signed using JWS and then encrypted using JWE.
Example: Assuming the below are the requested claims by the relying party
name : { "essential" : true }
phone: { "essential" : true }
Response 1: When consent is provided for both name and phone number:
{ "name" : "John Doe", "phone" : "033456743" }
Response 2: When consent is provided for only name:
{ "name" : "John Doe" }
Response 3: When Claims are requested with claims_locales : "en fr"
{ "name#en" : "John Doe", "name#fr" : "Jean Doe", "phone" : "033456743" }
