This text provides an impression of API-led structure utilizing Mule4 APIs to be able to give a transparent understanding of the event means of an API-led strategy. It covers all 3 of the API layers (System, Course of, and Expertise) utilizing Salesforce and FIRST.org because the supply. Moreover, we cowl making use of finest practices in every layer of improvement.

- Reusable traits, library, and response code in RAML
- Outline respective APIs with correct error dealing with,
international connectors
,logging
,munit testcases
