Integrating your Application using AffinitiQuest Touchpoints

The AffinitiQuest Credential Orchestration system provides an abstraction called "TouchPoint" (TP). TouchPoints provide easy integration for 3rd-party applications. A touchpoint is configured through the AffinitiQuest administration portal.

There are three primitive touchpoint types that can be configured:

Issue
- used to issue a credential and is bound to a particular credential design and issuer
- the 3rd-party may provide a webhook that can be used to fetch the attribute values that should be used in the credential
- the 3rd-party may provide a webhook that can be used to notify that a credential has been successfully issued.
Verify
- used to verify a credential and is bound to a particular proof design
- the 3rd-party may provide a webhook that can be used to notify that a credential has been successfully verified.
Revoke
- used to revoke a credential and is bound to a particular credential design and issuer

Each configured touchpoint is assigned a unique identifier.

TouchPoint Web APIs

GET /api/touchpoint/:touchpointId/auth

Requests a JWT token to be used with as a auth_jwt attribute with any of the touchpoint web components. HTTP Basic Auth Header:

Authorization: Basic <your-base-64-encoded-tenantId:api-key>

200 OK Response Body

access-token-in-the-form-of-a-jwt-string

GET /api/touchpoint/{touchpointId}/open

Kicks off the invocation of a TouchPoint.

HTTP Basic Auth Header:

Authorization: Basic <your-base-64-encoded-tenantId:api-key>

Query Parameter	Default	Notes
lang	"en-ca"	Optional: locale/language preference
format	"none"	Optional: enumeration: ["none", "html-tag", "html-page"]
layout		Optional: enueration: ["none", "minimal", "compact", "full"]
appContext	""	Optional: string representing the application context

Response is the touchpoint Configuration:

{
  "threadId": "<uuid>",
  "touchpoint": {
    "id": "<uuid>",
    "type": "<issue|verify|revoke>",
    "name": "touchpoint Name",
    "description": "description of touchpoint",

  }
}

If format is html-tag, then it can be injected into the browser DOM.

GET /api/touchpoint/{touchpointId}/open

render	"none"	Optional: enumeration: ["text/html", "none"]. Default "none" in which case the render property in the response will be null

}

ResponseBody with Content-Type: /application/json See ClaimsJwt Format For Issuance. See ClaimsJwt Format For Verification

TouchPoint Webhooks

TouchPoint Issue Attributes Request Webhook

If a TouchPoint entity includes a issueAttributesWebhookUrl then, upon TouchPoint open, the webhook will be invoked by issuing an HTTP GET to the specified url with any specified headers. An optional query parameter app_context may be provided if the open request on the webhook provided an app_context.

The invocation will be something like GET ?touchpointId=&jwt=&app_context=

This should return a JSON payload that describes the attributes to be populated in the credential. This should reflect the attributes described in the Credential Design created in the AffinitiQuest admin portal. The validFrom value defaults to the time of issuance. The validUntil value defaults to the time of issuance plus the expiry in the credential design. The format of the claims should reflect the values expected by the type of credential. For example, if it is a verified credential, it should contain the attribute values expected for that credential design schema. If it is an mdoc, it should match the expected mdoc format..

Attribute Name	Description
validFrom	optional - string indicating the mdoc validFrom date for the credential. Default is the time of issuance
validUntil	optional - string indicating the mdoc validUntil date for the credential. Default is the valueFrom date added with the expiry value defined in the credential design
claims	an object indicating the credential attributes or mdoc values

            "personalAttributeName2": "personalAttributeValue2",
          }
        }
      ]
  }
}

TouchPoint Success Webhook

If a TouchPoint entity includes a successWebhookUrl then, upon TouchPoint success the webhook will be invoked by executing an HTTP POST to the specified url with any specified headers.

Webhook Request Body
{
  "touchpoint": {
    "id": "touchpointid",
    "name": "the name of the touchpoint",
    "description": "Description of the TouchPoint",
    "type": "<issue|verify>"
  },
  "brand": {
    "id": "brandid",
    "name": "Name of Brand",
  },
  "appContext": "<Whatever app_context string was provided in the open request",
  "claimsJwt": "the JWT containing claim attributes that were issued or verified",
  "revocationHandle": "This will only be supplied on issuance for revokable credentials"
}

If the webhook consumer wishes to validate the received JWT, it must have access to the public key. This can either be provisioned in the webhook consumer app or it can retrieve it dynamically using the previously described web API GET /api/touchpoint/{touchpointId}/publickey/{kid}

Methods	Description
decodeJwt(jwtToDecode)	can be called from success event handler as `event.currentTarget.decodeJwt(event.detail.claimsJwt)`
asyncGetPublicKey()	can be called from success event handler as `const publicKey = await event.currentTarget.asyncGetPublicKey()`

<!-- example -->
<aq-touchpoint auth_url="/api/authenticate" tp_id="a uuid for a touchpoint" lang="en-ca" success_redirect_url="/membership-issued" />

The component will utilize the afore mentioned APIs. It further will change it's visual appearance and behaviour based on the TouchPoint Type that it receives as part of the response to the GET /api/touchpoint/{touchpointId}/open request.

Key Management

When claim attributes (either issued or verified) are being delivered to a 3rd-party application, they are provided in the form of a JWT asymmetrically signed using RS256.

As a result there is a need to generate and manage RSA keys used for this purpose.

Key Generation

When a new brand is created a 2048 bit RSA key pair will be generated and stored.

Signing JWT

When a touchpoint success event is being generated the RSA private key associated with the brand to which the TouchPoint belongs will be retrieved and used to sign the claimsJwt.
