APIM policy editor

What this editor does

An APIM policy is inbound/backend/outbound/on-error XML applied at a scope — JWT validation, rate-limit, cache, transform, mock. In Loom you load the policy XML for a scope, it validates well-formed XML client-side, and Save issues a real PUT.

Getting started

  1. Pick a scope — Choose the global, product, API, or operation scope whose policy you want to edit.
  2. Edit the XML — Author inbound/backend/outbound/on-error sections; the editor checks the XML is well-formed.
  3. Add common policies — Insert JWT validation, rate-limit, cache, transform, or mock policies.
  4. Save — Save PUTs the policy to the chosen APIM scope.
