Using the pdfservices-sdk-samples for Java.

Added the credentials to environment.


Not able to connect to Adobe API, issue appears to be about SSL certificate.

This was definitely not mentioned in the Get Started Guide.

    For what it’s worth, I find the SDKs more cumbersome than helpful. Consider calling the API directly through HTTP. You can use the Postman collection to automatically generate the Java code for each step in the process.
