Custom Functions
Write and deploy custom functions to extend how Transcend connects to your internal systems.
Custom Functions let you run your own TypeScript inside Transcend. Your code executes on your Sombra gateway as part of a workflow, which means it can reach systems that Transcend's cloud cannot, and the credentials it needs never leave your infrastructure.
Use them to respond to access and erasure requests from systems without a prebuilt integration, run preflight checks, or sync data between Transcend and your own services. The guides in this section cover the runtime, environment variables, testing, and common recipes.
Getting Started with Custom Functions
Manage your Custom Functions in the centralized Custom Functions page under Developer Settings.
