In this chapter, we have looked at the API underpinning BizTalk Services. We've seen how to leverage the API from the humble web browser and how to use PowerShell cmdlets and write our own code to invoke it. We've looked at the different types of APIs, capabilities, and the cmdlets that wrap all of them, and hopefully you've seen how you can make use of the capabilities of the BizTalk Services API to create, manage, maintain, and more importantly, automate your BizTalk Services instances. In the next chapter, we will look at troubleshooting your integration solutions and how to use the tracking capabilities of WABS.
