This gist explains how to integrate ServiceNow with Tanzu Application Platform Supply Chain

Problem Statement

Tanzu Application Platform leverages Cartographer's Supply chain to orchestrate the CI/CD Process. However TAP works with tools installed within the TAP Cluster like Tekton, Flux, Grype etc. In this Gist, we will look at integrating TAP with external tools like ServiceNow.

Note

For the purpose of this Demo - We took the liberty to integrate TAP Supply chain with the Snow's Incident module. However integrating with other modules like ChangeRequest, RITM, Task follows the same pattern. The only change would be to update the API call to point to the other modules.
