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.

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.

Prerequisites

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

QuickStart

1. Get API Key

   • Access Z.AI Open Platform, Register or Login.
   • Create an API Key in the API Keys management page.
   • Copy your API Key for use.
2. 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.

   

3. Create an n8n Workflow

   • In the n8n UI, go to Workflows → + New.
   • Add openai chat node in your workflow, and select ZAI Account as the credential.
   • Configure the openai chat node:
     • Model: glm-4.7

   

4. Run the Workflow

   • Click Execute Workflow to run the workflow.
   • The response will be available in the Output tab.
