Multiple Content Types in single request

[API-Evangelist]

Hello there,

We need to post request with below parameters from apigee.

Here are the parameters for the POST request:

• Front: A file parameter containing the front image data in binary format.
• Back: A file parameter containing the back image data in binary format.
• Item: The Item parameter contains XML.

Front,Back in binary format & Item in XML are been extracted from prior response & need to construct the request to submit as a new request but how to add multiple types of content in single request?

This is to submit a check images(front/back & sample item details) to a vendor.
