Salesforce Functions Developer Guide
A Function is your code, run on demand, in Salesforce Functions elastic trusted compute environments. Upload your complex business logic code, written using your preferred languages and frameworks, and Salesforce Functions takes care of everything else necessary to invoke your code in a secure and self-scaling environment.
Use this guide to understand the full developer workflow for developing and invoking Functions.
