How to use

a11y.sectionLink How to use

1. Start by creating a new function.
   • Specify the API Endpoint
     • Enter the full URL of the API
     • Choose the correct HTTP method (GET, POST)
   • Define the inputs
     • Define all required inputs for the API, including
       • Query parameters
       • Headers
       • Body
     • For each input, specify:
       • Name
       • Input type (static, input, function parameter)
         • For any input marked as a function parameter, be sure to add a clear description — this is what the LLM sees when deciding how to fill in values.
         • If it’s a body field, also specify the type (e.g., text, whole number, etc.)

2. Run a Test Execute to validate the function.
   • Make sure the LLM is collecting the correct information from the conversation (e.g., query parameters, headers, or body fields) needed to make the API call.
   • Note: This works alongside other functions such as Internet Search.

3. Verify that the function is called successfully.
   • Once the function is triggered, a collapsed section will appear in the chat showing the function call details.
   • In the input section, you should see the function name and all provided inputs.
   • In the output section, you should see the API response.
