Hi @kakar thanks for the screenshots, what I don't see in there is the base 64 encoding of your Client ID and Secret before you send the postman auth request. Add this code to do the same inside of "Pre-request Script". Note that you need to have those as environment variables or you can just hard code those values inside of this script.
Give it a shot and let me know the result.
// Populate the Postman environment with: // RC_SERVER_HOSTNAME, RC_APP_KEY, RC_APP_SECRET, // RC_USERNAME, RC_EXTENSION, RC_PASSWORD var appKey = environment["RC_APP_KEY"]; var appSecret = environment["RC_APP_SECRET"]; var apiKey = encodeBasicAuthHeader(appKey, appSecret); postman.setEnvironmentVariable("basic_auth_header", "Basic ".concat(apiKey)); function encodeBasicAuthHeader(appKey, appSecret) { var apiKey = appKey + ':' + appSecret; return btoa(apiKey); }
Hello all,
i am trying to use rest api for devtest password based authorization. but i am get error "Unsupported grant type" with error code "OAU-250"
Hi @kakar
Request you to remove the attachment and re-upload it with your password blurred out.
To answer the question, the content type you are using seems to be incorrect form-data in the body tab of postman
Please refer to the API docs here
The correct content type for oauth request should be "application/x-www-form-urlencoded".
Could you please try that?
Hope this is helpful
I see you're trying to hit the Production API Endpoint URI: https://platform.ringcentral.com/restapi/oauth/token are your keys being used for that environment or are they for the Sandbox API Endpoint URI: https://platform.devtest.ringcentral.com/restapi/oauth/token ?
Are the user credentials being used associated with the appropriate environment?
