Hi ,

Thanks for your response. I have resolved the issue. However, to answer your questions:

I was developing a block of code using Python which returned a pdf to Appian.

When doing this, we do not have to actually write the code for document to base64 conversion, just need to pass the file path to the request object. As done below:

As for Postman, we can test the API by uploading the file from your local storage to Postman under the BINARY sub-section in BODY section.

Hopefully, this information is of use for someone else in the future. Thanks for your response though.

Frist, there is only a single variant of base64 encoding.

Can you share the configuration and the code of that web API?

Can you try to use curl to call that API? That might remove some of the uncertainties of Postman.

Hello ,

I actually found the issue. I do not have to convert the files into its base64, rather just use the 'binary' option under the BODY in Postman, upload the required file and voila, it worked.

The same needs to be done in the code block at the external system's API endpoint.

Highly appreciate your time and replies though. Cheers!
