TI store API suite - Authentication

Authentication

Because TI store APIs are secured using OAuth 2.0, you must pass an access token when sending a request. To obtain an access token, call the OAuth API at https://transact.ti.com/v1/oauth/accesstoken.

For a successful request, note that:

We use the client credentials flow.
The "Content-Type" must be "application/x-www-form-urlencoded".
The request should be sent to the appropriate URL above without any additional query parameters.
The request parameters (grant_type, client_id, client_secret) must be in the request body, sent in a string, separated by "&" without any further encoding.
For example: "grant_type=client_credentials&client_id=[CLIENT_ID]&client_secret=[CLIENT_SECRET]"
The access token is valid for 60 minutes. Before using the token in other APIs, check whether the access token has expired.

curl --request POST \   
       --url https://transact.ti.com/v1/oauth/accesstoken \   
       --header 'Content-Type: application/x-www-form-urlencoded' \   
       --data grant_type=client_credentials \   
       --data client_id=XXXXXXXXXXXXXXXXX \   
       --data client_secret=XXXXXXXXXXXXXXXXX

Response for a successful request:
