Attaching Tools to Assistants

After creating a tool, attach it to an assistant to use it during calls. Manage tool assignments through the Assistant API:
  • Create Assistant - Use the tool_ids parameter to attach tools when creating an assistant
  • Update Assistant - Use the tool_ids parameter to add, remove, or replace tools on an existing assistant
