Integration between Salesforce and Adobe

Hi,

I'm doing integration between Adobe PDF Service and Salesforce using APIs. Our main goal is to convert HTML file (i.e. stored in one of salesforce standard object 'ContentDocument') to PDF and stored that generated PDF file back to salesforce. I have performed below steps in my apex class:

1. Generate access token using client_id, client_secret and jwt_token
2. POST method to convert HTML file to PDF, Here I need some guidance. So, here which url I can use from salesforce and pass it as a value of inputUrl. Here is the SS of postman and i'm doing same steps in my apex class:

I really appreciate your help in advance..!

Thanks,

Hetal
