OOTB36: Salesforce External Client App Tutorial Step-By-Step OAuth Client Credentials & Postman Demo
Salesforce External Client Apps (ECA) are the modern replacement for Connected Apps, built with stronger security, better packaging support, and full metadata portability.
In this video, we walk through External Client Apps step by step, starting from settings and creation, all the way to generating access tokens and fetching Salesforce records using Postman. You’ll learn how ECAs support 2GP, how they differ from Connected Apps, and why Salesforce recommends them for new integrations.
This tutorial is ideal for developers, architects, and admins working on API integrations, OAuth authentication, or AppExchange-ready solutions.
