Introduction to Custom Endpoints

Custom endpoints allow you to extend the functionality of your workspace by writing hosted C# functions that handle incoming HTTP requests.

Creating Endpoints: Defining paths, authorization, and execution modes.
Endpoint Tokens: Managing authorization for external calls.
Calling Endpoints: How to invoke your code from external apps or the front-end.
Execution Scopes: Built-in objects and methods available in your code.
Importing Endpoint Code: Sharing helpers across endpoints and AI tools with //ImportEndpoint.
Auto-generated Helpers: Using strongly typed helpers to access node types and fields.
Searching from Endpoints: Running indexed search with CreateSearchAsUserAsync and CreateSearchAndFacetsAsUserAsync.
Similarity & Vector Search: Vector indexes, Similar(), StartAtSimilarTextAsync(), and the multi-signal similarity engine.
Security Best Practices: Protecting your data and endpoints.
Graph Query Language: The full IQuery interface reference for endpoints, shell, and data connectors.
Debugging: Tips for testing and troubleshooting endpoint logic.
