# n8n Workflow

> Build n8n automations that call Z.AI GLM models

n8n lets you orchestrate API workflows without code. This guide shows how to call Z.AI's GLM models inside any n8n workflow using the OpenAI node.

<Warning>
  When you are subscribed to the **GLM Coding Plan**, switch the base URL to `https://api.z.ai/api/coding/paas/v4` instead of the general API endpoint used below.
</Warning>

## Prerequisites

* An n8n deployment (desktop, self-hosted, or n8n Cloud)
* Basic familiarity with n8n nodes

## QuickStart

<Steps>
  <Step title="Get API Key">
    * Access [Z.AI Open Platform](https://z.ai/model-api), Register or Login.
    * Create an API Key in the [API Keys](https://z.ai/manage-apikey/apikey-list) management page.
    * Copy your API Key for use.
  </Step>

  <Step title="Configure n8n Credentials">
    * In the n8n UI, go to **Credentials → + New**.
    * Select **OpenAI** (use the OpenAI node to call Z.AI's Inference API).

    * Configure the credential:
      * **Name**: `ZAI Account`
      * **API KEY**: `YOUR_ZAI_API_KEY`
      * **Base URL**: `https://api.z.ai/api/paas/v4`
    * If you use the GLM Coding Plan, use the `https://api.z.ai/api/coding/paas/v4` as the base URL.
    * Save the credential and will auto test the credential to make sure it works.
