Hello,
I recently documented the process of connecting an authenticated external REST API to Salesforce Flow, including the exact configuration and troubleshooting steps along the way.
I've published a guide covering:
o Quick installation of a working example
o Building the integration from scratch using Salesforce's credential and HTTP Callout configuration
o Adapting the Flow to an existing record-triggered workflow
o Modifying the configuration to work with other REST APIs
The goal is to make the process easier to reproduce, particularly for developers who want to call external APIs without writing Apex.
I'd appreciate feedback from people who have built similar integrations: Is this approach useful as a general recipe, and are there any important steps or edge cases I should cover?
The guide details are available here:
https://github.com/ezchx/Salesforce-IndieML-Flow-Integration/blob/main/README.md
The working example uses my IndieML Substance API, but the guide also explains how to adapt it to other APIs.
Thank you for your consideration.
