Extract PDF -> Upload PDF put method is returning 403 from within SAP ERP

Hi community,

would really appreciate the swarm knowledge to help me solve my riddle. I want to use Adobe Extract PDF API from within a SAP ERP report I am currently coding. I implemented all steps as I have tested them in Postman, all working fine there.

In SAP I encountered the problem during the put method to upload the PDF (as binary data), that the response was always the below 403 Forbidden. I installed a certificate in STRUST for *s3-accelerate.amazonaws.com, but that may be wrong according to the error? 

Thanks,
André
