Document Management Solution GroupDocs.Conversion Cloud API Authentication Issue

Hello, I have created my first app and stored file in it, now trying to test conversion API, when I attempted to test at https://apireference.groupdocs.cloud/conversion/, I have entered App SID and AppKey provided in the dashboard, but I keep receiving Auth Error Error: Bad Request, error: invalid_client.

Please help me to solve this issue.


Please double check your credentials from GroupDocs Dashboard. Please click on the lock icon to view your App Key. The credentials should be like as follows. Hopefully it will resolve the issue.

//dummy values
APP_SID = “7b854efb-6e7c-678e-b89b-e89d78e13456”
API_KEY = “89fb43e80f2345d022a567888136e041”

@tilal.ahmad, yep I am using the same, but receiving an error.

what is the CURL request to get the Oauth Token, I can try the same from Postman tool


My postman request

The Postman is working fine at my end with my credentials. Please share your credentials in a private message (click on my username in the post and use message tab for private message). We will look into it and will guide you.

Hay, I have to switch to corporate account for further POC. I have solved Auth issue. instead of sending client_id and client_secret, i was sending it AppSID and AppKey.

Now testing storage and conversion function, here is what I have

App Name : First App
Stroage: FirstStorage

I have authenticated with API successfully, and playing with storage calls but getting a different response


But API version 1.1 is working fine.


“isExist”: true,
“code”: 200,
“status”: “OK”

Could you please help me what I am doing wrong?


Please note API Version V2 uses JSON Web Token(JWT) for API request authentication. However, API Version 1.1 uses OAuth 2.0. Hopefully it will help to resolve the issue.

// Get JWT Access Token
// Get App Key(client_secret) and App SID(client_id) from https://dashboard.groupdocs.cloud/
curl -v "https://api.groupdocs.cloud/connect/token" \
-d "grant_type=client_credentials&client_id=xxxx-xxxx-xxxx-xxxx-xxxxxxxxx&client_secret=xxxxxxxxxxxxxxxxxxxxxxxxxxx" 
-H "Content-Type: application/x-www-form-urlencoded" 
-H "Accept: application/json"

// Check If storage Exists
curl -X GET "https://api.groupdocs.cloud/v2.0/conversion/storage/First Storage/exist" 
-H "accept: application/json" 
-H "authorization: Bearer [JWT_Access_Token]" 
-H "x-aspose-client: Containerize.Swagger"

I am doing exactly the same from postman as described in the documentation, got the token successfully sending token through HTTP Authorization header.

Note : My storage space name is “FirstStorage” not “First Storage”, I have renamed it

Here is postman log
