API Request | Langflow Documentation

The API Request component constructs and sends HTTP requests using URLs or curl commands:

URL mode: Enter one or more comma-separated URLs, and then select the method for the request to each URL.
curl mode: Enter the curl command to execute.

You can enable additional request options and fields in the component's parameters.

Returns a Data object containing the response.

For provider-specific API components, see Bundles.

Some parameters are hidden by default in the visual editor. You can modify all parameters through the Controls in the component's header menu.
