store non- mobile user Login tokens in clientData and fetch tokens whenever required in mobilefirst

Question

I Want to test MFP adapter 8.0 using Postman

Steps followed -

1. Registered the confidential client in MobileFirst Operations Console.
2. Using Postman, Obtained access token from MobileFirst Server token endpoint.

I am able to get access token using url - /mfp/api/az/v1/token

3. And used the access token received from MobileFirst Server token endpoint to make requests to the desired resources.

Now can I know how to store Login tokens in clientData and fetch tokens whenever required using -

clientData.getProtectedAttributes().get("");

Currently getting null pointer exception while getting clientId from clientData

String clientId = (String) clientData.getProtectedAttributes().get("clientId");

Update : Attached snapshot of Request parameter passed for Token step https://i.stack.imgur.com/XVhLV.png

Answer 1

The observed behaviour is expected and by design.

A confidential client does not have a clientId and no associated clientData.Client Data is populated only when using mobile SDK to do registration and subsequent operations.
