Getting Error while obtaining an access token in HMS Push Kit API

Question

When I use this api to get access token:

https://oauth-login.cloud.huawei.com/oauth2/v3/token?grant_type=client_credentials&client_id=****&client_secret=****

it always returns

{
    "sub_error": 20001,
    "error_description": "missing required parameter: client_id",
    "error": 1102
}

although I send client_id parameter

Answer 1

To solve the issue, Please make sure the below points

1. You are doing post request to the server

2. Make sure that the POSR URL is “https://oauth-login.cloud.huawei.com/oauth2/v3/token”.

3. Do not include post parameters in the URL, Add below parameters in body of POST request(If you use postman tool you can find the feilds for adding parameters)

   grant_type=client_credentials

   client_id= Your Client ID

   client_secret= Your Client secret
