  Hi,

  I am using WordPress cloud website hosted on WordPress.com. i am able to execute the Rest API through the developer console browser(https://developer.wordpress.com/docs/api/console/) but was unable to execute them through postman.
  These are the steps i followed.

  1. Created an application for the WordPress site on the application manager (https://developer.wordpress.com/apps)
  2. Gave same callback url both on postman and the application.
  3. The application manager generated client id (which is a numeric value) , Client secret (alphanumeric value) , redirect url , token url , auth url.
  4. in postman i followed the following steps:
     • Clicked on OAUTH 2.0 and selected the following:
     • Token Name: name for my token.
     • Grant Type: Authorization Code.
     • Auth URL: https://public-api.wordpress.com/oauth2/authorize.
     • Access Token URL: https://public-api.wordpress.com/oauth2/token.
     • Client ID: From my WordPress app.
     • Client Secret: From my WordPress app.
     • Callback URL: Same as the one configured in my app.
     • Client Authentication: Send as basic Auth Header.

  • When i click on Get New Access Token , i was redirected to my website and was able to approve the request , then it redirected me back to the postman where i am getting this error
    Error: invalid_client, Description: The required “client_id” parameter is missing.

  I am providing the client id but it is giving the same error again and again , i tried – clearing previous cookies , created a new application connection , checked the redirect url , still it is giving me the same error.
  Please help me in setting this connection , and update if there’s some another way to connect the API though postman.

  Please Note, I want the solution for the cloud hosted instance i.e., wordpress.com
