Hi everyone,

I’m trying to replicate a working Postman API request inside my Pega application using a Connect REST rule.

In Postman, my request configuration is as follows:

• Method: POST

• Body Type: form-data

• Fields:

  •  

  • file: (actual file upload, e.g., PDF or text file)

• Postman automatically sets:
  Content-Type: multipart/form-data; boundary=----WebKitFormBoundary12345

This setup works fine in Postman and successfully uploads the file.

Now I’m trying to do the same in Pega, but I’m unsure about the exact configuration steps for:

1. The Request tab (how to map multipart/form-data parts correctly)

2. Mapping the file content (should I use .pyAttachStream?)

3. Whether I need to convert the file into binary or Base64

4. Whether I should manually set the Content-Type header, or let Pega handle it automatically

Can someone please explain or share a sample Connect REST configuration that matches a Postman form-data request with a file upload?
Screenshots or best practices would be very helpful.
