Oauth2 Authentication



I created a profile. Put my client_id and client_secret into POSTMAN along with the parameter "grant_type" and the value "client_credential". All I can get from Caspio is 


    "error": "invalid_client"
What other information do I need to include with the request?
I've read the documentation. 
grant_type=client_credentials&client_id=<Client Key>&client_secret=<Client Secret>
That list of URL Parameters is exactly what I'm sending.
I've gone back into Caspio Access Permissions and refreshed my client_id and client_secret and saved the changes. With the new id and secret, I'm getting exactly the same error message.
Please Help

Hi cflanagan,


Welcome to Caspio Forum!


I have found the following information on the page:

"Caspio Authentication server supports only “client credentials†flow at the moment, so only confidential clients, clients capable of maintaining the confidentiality of their credentials (e.g., client implemented on a secure server with restricted access to the client credentials), or those capable of secure client authentication using other means are supported."


Please make sure that your authentication is supported at the moment.
