Authentication with Thrust Services Free Trial cannot get Core content API's connected

Poojitha

I am trying to get core content storage services using free trail and access it via API's

I have added core content management free trail in tenant.

I have created service key for the same in the tenant and tries this keys to authenticate with CSS API's, unable to get bearer token instead getting 401 unauthorized

also extended the same core content app and got the client id and client secret, still facing same issue.

Is there anything still missing?

@Poojitha , to be able to use the CSS API to access the files you uploaded in Core Content you best use an Extension App.
Use the following steps to test this:

1. Open https://developer.opentext.com/
2. Login with your free trial account
3. Open Admin Center for your organization
4. Under App management open Apps
5. Create extension app !! still on organization level !!
6. Fill in details
   
7. Be sure to copy service client, this is what you need
8. Now open https://developer.opentext.com/services/products/content-storage-service/apis/information-storage-css-3-0-0
   or on https://developer.opentext.com/ navigate to APIs and then in the side menu to CORE APPS → Apps → Core Content Management → APIs → Core Content - Storage
9. Click Authorize
   
10. Fill in the tenantId, client_id and client_secret and be sure to do this for the section where the url is that of the region your organization is created, for example us. Then click Authorize.
    When this was successful the button changed to Logout. Click Close to close this dialog.
11. Click on the GET /v3/files endpoint and then click the Try it out
    
12. Click Execute to send the request
    
13. Response is 200 OK. The files of files is empty as this endpoint only shows files uploaded by the requestor. Use the CMS service to discover the files that are uploaded into Core Content.
    Response 200 OK for the GET /v3/files endpoint
    In case you retrieved the fileId via CMS then you can use that to get the file details.
    Response 200 OK for the GET /v3/files/<fileId> endpoint

This shows how to use the CSS service.

Important things to check are the url endpoints and service client details.
The url endpoints show match the environment where you organization is created.
The service client should be created or used from organization level only. It is not possible to use a tenant level service client and mix that with the organization level endpoints.
