Using the Tokenized Deposit Application Wrapper APIs

The tokenized deposit application scenario supports issuance and distribution of funds with minimal governance overhead.

See: Tokenized Deposit Application

Authentication

Secured endpoints require a bearer token in the authorization header:

Authorization: Bearer <access_token>

The proxy validates the token in accordance with the deployment configuration (for example, following command to generate a bearer token by using the access token endpoint that is available in the Blockchain Platform Manager.

curl -sS -X POST \
  "<Access Token Endpoint – fetched from Blockchain Platform Manager>" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=password" \
  -d "client_id=<CLIENT_ID>" \
  -d "client_secret=<CLIENT_SECRET>" \
  -d "username=<USERNAME>" \
  -d "password=<PASSWORD>"

The following text shows an example response. You then use the value of access_token as the bearer token for subsequent calls.

{
  "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9....",
  "expires_in": 300,
  "token_type": "Bearer"
    ...
}

Authorization

WCBDC uses role-based access control. See:

Quick Start

Execute your first cURL call and validate your configuration by using the following example which retrieves readiness of the application.


curl -X GET \
  "<Wrapper_API_URL>/V1/ready" \
  -H "Accept: application/json"
