How to generate authentication token/signature for Aspose.Slides Cloud for cURL requests

how do i generate the signature in order to use the curl requests


Thank you for contacting Aspose Support.

We would recommend you use OAuth 2.0 protocol instead of URL Signing for APIs authentication. Following is a cURL example to get Access Token:

// cURL Example to get Access Token
// Get your App Key and App SID from
curl -v "" \
-d 'grant_type=client_credentials&client_id=0B17F60A-6D69-426B-9ABD-79F35A6E9F7B&client_secret=53b8b19adffa41a3e87dbbd8858977ae' \
-H "Content-Type: application/x-www-form-urlencoded" \
-H "Accept: application/json"

Then use received access_token to call any Aspose Cloud API:

// cURL example to upload file to Aspose Cloud Storage
curl -v "" \
-X PUT \
-T testfile.txt \
-H "Content-Type: multipart/form-data" \
-H "Accept: application/json" \
-H "Authorization: Bearer qyc9asneEZsTZtRro3Qd2ZH38jQdBLabtIi5nE3DPgdbGolk0K8RQwB1kC1umqfp4rAKeP8gFTIRSRhl6uShnbX70X-_ieDHPAK1cCAH1Kiq6fz8lnHZc-zXmHir_TxsXrjvsjMGDwRmhjncUDMPhEU4Ah8rq0XT-8Q_dz2lWCnJsrYMXp8S2jf0QRb3xmIT5Bw1lRxsDa9PeBQ9BxDPBNYBepAUKkjNCSywA4nnoAIBeKc6mt7cmIO3J3Kv4mYk_r2z1Mog_lgmFmzYrLLPTcKNUzFHOtSAjMlz8Tn2uyihbfXJVqu7pCDd6I1yIxvcHbNIgBd01tFTjQpHUh_Pr5sKyhXg0RYLZNOSrREuRqcR04mSfR_E9RsN5k1TReZxhfUY8oacfCeUIMysGOvGB-F9J5DR41DwkxrezAeYUPE8hGBm"

As an update, please note now Aspose Cloud APIs start a support of JSON Web Token(JWT) authentication as well. New API Version of Aspose.Slides Cloud only supports JWT authentication. However, old API Versions continue to support OAuth 2.0.
