Cannot Fetch Access Token

I have tried requesting the access token via both the Postman library found here: https://devcommunity.ringcentral.com/ringcentraldev/topics/postman-collection

as well as via a CURL request. In each case I get a different error but still cannot generate an access token.


I am using my Client ID and Client Secret found under the credentials area (Are these right?).


Any who,


CURL Request:


curl -X POST "

Hi Jordan,

Could you please check the application type, login to developer portal (  https://developer.ringcentral.com ) and click on the application and under settings you should see the "Platform Type". If the platform type is any one of below :
  • Browser-Based
  • Server-Web
  • Server-Only
Then you would need to follow the OAuth 2.0 Code flow for authentication. 

Please look up this discussion  https://devcommunity.ringcentral.com/ringcentraldev/topics/unauthorized-for-this-grant-type-error for more information.

Let us know if you have any question.

Hello to any future readers,
Thanks to the help of Anil @ RingCentral, I realized I was just making a dumb mistake by not reading documentation properly!

In the developer site there was a top level account phone number, I was trying to authenticate with this number and extension as opposed to my developer number (not this is a test account). 

I do feel the error message that was returned could be improved as it did not necessarily address the case I was running into. 

Issue is resolved however by using the right darn phone number!

@Jordan,

I agree with you on the error message that we should provide for this particular 'use case'. I will convey this to my team. Thanks for the feedback!

Happy Coding!

First you need to go through using OAuth with Authorization code grant_Type and need to know how to put Authorization header .

Please check here:
