Attachments Request v1

Summary API Attachments FAQ CHANGE LOG     


The Attachment Request API allows customers to request for additional medical documents in response to the medical claims. The Request API takes the request payload and delivers in a format understandable by the receiver.

An attachment, in the context of healthcare electronic data interchange, is an electronic rendition of medical documentation, such as an X-ray, lab report, or questionnaire, that supports a healthcare administrative transaction.

API Onboarding

See the Security and Authorization section in this portal to learn more about using our APIs. Most of our APIs are private and require credentials to gain access.

Getting Started

There are two easy ways to explore the data in our API's.


Start using our postman collection.

  • If you don't already have postman, you can download it here: Postman

  • Import our example collection: Run in Postman

  • Download the environment config: Postman Environment

  • Add your Client Id and Client Secret values to the MN-ClientId and MN-ClientSecret postman environment variables.

Why Postman?

Postman provides an easy UI for testing an API, as well as being the easiest way to start exploring Attachment Transform API. We recommend starting with our postman collection to understand what is available within the API.

What information needs to go in the request header?

In the header for an Attachment Request API request, you need to pass an authorization token. For more information on this please visit Security and Authorization This is a precursor to making an Attachment Request API call, which might have the following headers:

Content-Type: application/json \
Authorization: Bearer <Your-Access-Token>

When you're ready for production, simply remove sandbox from the URL.
