BizTalk Server 2020: End-to-end Scenario – Receiving messages through the HTTP adapter whitepaper

The role of an adapter is to enable communications between BizTalk Server and external systems and trading partners. Users configure adapters by creating send ports and receive locations that define the properties for given instances of the adapter. Most adapters support both send and receive operations, whereas other adapters support communication in only one direction.

The HTTP Adapter is one of the adapters that support two-way communications, but unlike other adapters, this adapter has two characteristics that define it:

  • The HTTP “Receive” Adapter that is responsible for delivering messages to BizTalk is, in fact, a DLL that runs inside Internet Information Services (IIS)
  • And for that reason, it must be configured in IIS – it is not there out-of-the-box.

In this whitepaper, we will describe the step-by-step process of installing and configuring the HTTP Adapter in order to receive messages.

Some of you may think that the HTTP adapter is deprecated, but that is not true. The only adapters that were deprecated were the old SAP adapter (removed) and the SOAP and SQL adapter (that still are present in the Administration Console). The HTTP adapter is a classic but is not deprecated and is still very used today.

The idea for this whitepaper was partly out of a real need and at a customer’s request. Because it is a strange adapter with a peculiar configuration unlike any other adapter in BizTalk Server, when I was giving a training course, the attendees struggled to understand and put it working correctly. By coincidence, a week later, I needed to put this adapter working at another client.  As a result of that request and that client’s need, I end up creating this step-by-step guide on how to install and configure the HTTP adapter to receive messages through HTTP requests. I think this is a good whitepaper about a classic adapter in BizTalk Server.

There is a similar whitepaper that I wrote in the past: BizTalk Server 2016: Receiving messages through the HTTP Adapter installation whitepaper focus on BizTalk Server 2016 as the name describes. This new one is just a small update on the BizTalk Server versioning and is to be updated with the latest version of the BizTalk Server.

What’s in the Whitepaper for you?

This whitepaper will give you a detailed understanding of the following:

  • Prerequisites
  • Configure the HTTP Receive Adapter in IIS
  • Configure the HTTP Adapter Receive and Send Handlers
    • Receiving messages using the HTTP Adapter
    • Testing our solution
