https://waha.devlike.pro/blog/waha-n8n/

---

Here's how you can start developing your WhatsApp automation with using n8n and WAHA in pair so you can create
your own no-code or low-code WhatsApp automation:

Installation

Here's a quick docker-compose we have prepared for you to start using n8n with WAHA:

wget https://raw.githubusercontent.com/devlikeapro/waha/core/docker-compose.n8n.yaml
mv docker-compose.n8n.yaml docker-compose.yaml

• If you're using WAHA Plus (donation version) - kindly go to https://portal.devlike.pro and docker pull the image with your credentials:

docker login -u devlikeapro -p <dckr_pat_1111111111>
docker pull devlikeapro/waha-plus
docker logout

• If you're using WAHA Core (free version) - you can use the image from Docker Hub:

sed -i 's/devlikeapro\/waha-plus/devlikeapro\/waha/g' docker-compose.yaml

Now you're ready to run:

docker compose up 
# to run in background:
# docker compose up -d

After that, open:

1. n8n at https://localhost:5678 and set up your email/password
2. WAHA at https://localhost:3000/dashboard (waha/waha)

Install WAHA n8n node

We provide WAHA Node, which you can install at your n8n installation.

Go to your n8n => Settings => Community nodes and install:

@devlikeapro/n8n-nodes-waha

First WhatsApp workflow

We'll build simple workflow - when your WhatsApp account got any message,
it responds with "Hi there" message

Step 1: Add WAHA API credentials

Before starting using the node, you need to add WAHA API credentials.

1. Go to your n8n => Home => Credentials => Add first credential
2. Find WAHA API in dropdown
3. Host URL - http://waha:3000 or use your domain
4. API Key - 321 or your API key set in docker-compose.yaml
5. Click Save - it'll check the connection and save the credentials

If you need help with that, check the
Create credentials

Step 2: Create a new workflow

1. Go to n8n => Home => Workflows => Create new workflow.
2. Remove Manual trigger

Step 3: Add WAHA Trigger

Add WAHA Trigger node.

Step 4: Add Send a text message action

Add Send a text message WAHA Action and connect it to message WAHA Trigger output:

Step 5: Activate the workflow

Click Save and Activate the workflow:

Step 6: Start a new session

Open the WAHA Trigger and expand Webhook URLs => Production URL

Go to http://localhost:3000/dashboard/ (waha/waha) and
Start New session with the URL you got from the WAHA Trigger:

Scan QR and wait till session in WORKING state:

Step 7: Send a message
