Publish flows

Langflow provides several ways to publish and integrate your flows into external applications. Whether you want to expose your flow as an API endpoint, embed it as a chat widget in your website, or share it as a public playground, this guide covers the options available for making your flows accessible to users.

API access​

The API access pane presents code templates for integrating your flow into external applications.

The JavaScript API tab displays code to interact with your flow in JavaScript.

  1. Copy and paste the code into a JavaScript file.
  2. Run the script.

_10
node test-script.js "tell me about something interesting"

The response content depends on your flow. Make sure the endpoint returns a successful response.

Temporary overrides​

The Temporary overrides tab displays the available parameters for your flow. Modifying the parameters changes the code parameters across all windows. For example, changing the Chat Input component's input_value changes that value across all API calls to the /run endpoint of this flow.

Send files to your flow with the API​

For information on sending files to the Langflow API, see API examples.

Shareable playground​

The Shareable playground exposes your Langflow application's Playground at the /public_flow/{flow-id} endpoint.

You can share this endpoint publicly using a sharing platform like Ngrok or zrok.

If you're using Datastax Langflow, you can share the URL with any users within your Organization.

Embed into site​

The Embed into site tab displays code that can be inserted in the <body> of your HTML to interact with your flow.

For more information, see Embedded chat widget.
