The functions area of the API covers two related families: Functions (classic serverless Python functions) and Function Apps (function applications identified by external IDs, with calls, logs, and related operations).

​
Function Apps vs Functions APIs

  • Functions (/functions/...) — Deploy and manage function definitions, schedules, and calls using the traditional Functions resource model (function IDs, schedules, call history, and logs).
  • Function Apps (/function-apps/...) — Manage function applications by external ID, including calls, response and logs for a call, and Model Context Protocol (MCP) operations where exposed in the API reference.
Choose the Functions endpoints when you work with standard CDF functions and schedules. Choose Function Apps when you integrate with the Function Apps paths and external ID–based application flows described in the API reference.

​
APIs in this group

  • Functions — Deploy and manage serverless Python functions
  • Function calls — Invoke functions and track execution
  • Function schedules — Schedule recurring function invocations
  • Function Apps — List and manage function applications and their calls (/function-apps/...) as documented in the API reference for your calendar version
