# Using n8n with LangBot

Source: https://langbot.app/docs/en/usage/pipelines/n8n

Integrate n8n with LangBot to drive AI bot workflows and automations across messaging platforms.

[n8n](https://n8n.io/) is an open-source workflow automation platform that allows you to create, schedule, and execute various automated tasks.

LangBot currently supports triggering workflows and receiving responses through the `Webhook` node in n8n workflows.

## Using n8n as the runner

Please open the configuration page of an existing pipeline or create a new pipeline (recommended) and open the configuration page. Select `n8n Workflow API` as the runner in `AI`.

Then configure and fill in the other settings according to the content below.

Select `Webhook` or `On chat message` as the trigger and configure as follows:

Configure the node that calls the AI model as `AI Agent`, following the setup below:

> For streaming responses, add the items highlighted in the red box. If you don't need streaming, you can skip this.

For the workflow response content in n8n, please use the `Respond to Webhook` node and configure it according to the image below (if you choose streaming responses with the `AI Agent` node, you do not need this step):

The response content key name in `Response Body` needs to match the `output key name` in LangBot's pipeline configuration.

After completing the n8n workflow configuration, please click `Active` at the top to enable the workflow.
