How to authenticate Aspose.Slides Cloud API Requests using cURL

klubar · July 15, 2019, 5:21pm

Unfortunately I can’t get Aspose.Slides Cloud - API References to work, so I’m trying raw curl examples…

[Alternatively, do you have an packaged Postman [https://www.getpostman.com/] samples]?

What am I doing wrong here:

Step 1 get a token:

 curl -v "https://api.aspose.cloud/oauth2/token" \
 -X POST \
 -d 'grant_type=client_credentials&client_id=0000000-0000-0000-0000-80f904d730bf&client_secret=000000768f4e1f53e7fb4a8fab0108d' \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

(note, modified client_id and client_secret for public posting)

Got a response:

Then tried to execute call:

(putting in the bearer token from my get token CURL)

I get the following error:
{“error”:{“code”:“error”,“message”:“You must either set Authority or IntrospectionEndpoint”,“description”:“Operation Failed.”,“innerError”:{“requestId”:null,“date”:“2019-07-15T17:18:53.628759Z”}}}

What am I missing?

@klubar

Thanks for your inquiry. I am afraid we have not Postman samples but cURL samples. You can find sample cURL examples on each documentation page.

Please note API version 3.0 only supports JWT(JSON Web Token) authentication. Please check following sample cURL command to get JWT for authentication.

// First get JSON Web Token for authentication
// Get App Key and App SID from https://dashboard.aspose.cloud/
curl -v "https://api.aspose.cloud/connect/token" \
-X POST \
-d "grant_type=client_credentials&amp;client_id=[APP_SID]&amp;client_secret=[APP_KEY]" \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"
