We can also perform the conversion of JPG to PDF using cURL commands. As a pre-requisite, we need to execute the following command to generate the JWT access token.

curl -v "" \
-d "grant_type=client_credentials&client_id=bbf94a2c-6d7e-4020-b4d2-b9809741374e&client_secret=1c9379bb7d701c26cc87e741a29987bb" \

Once the JWT is generated, please execute the following command to generate a blank PDF document and save it in cloud storage.

curl -v -X PUT "" \
-H  "accept: application/json" \
-H  "authorization: Bearer <JWT Token>"

Now we need to execute the following command to place the JPG image inside a PDF document.
