How toEvaluate Chains
Use API nodes within chains
Make external API calls at any point in your Prompt Chain to integrate with third-party services. The API node lets you validate data, log events, fetch information, or perform any HTTP request without leaving your chain. Simply configure the endpoint, method, and payload to connect your AI workflow with external systems.
Configuring API nodes
Create an API node
- Drag from the start node or any existing node to create a connection
- Select API from the node type menu
API node editor
Configure HTTP API requests with standard parameters and custom scripts. The editor provides a complete interface to set up your API endpoints.
Request configuration
- Select HTTP methods (GET, POST, PUT, DELETE)
- Add request headers
- Configure query parameters
- Define request body
Advanced options
- Write pre-request scripts to modify request parameters.
- Add post-response scripts to transform API responses.
- Test API calls directly from the editor.
Select output field (optional)
Click run to test your API endpoint. By default, the entire response body is set as the node output. To use a specific field from the response use the Select output field dropdown to choose the desired response field.
