Webhook and WhatsApp Business Cloud integration
Save yourself the work of writing custom integrations for Webhook and WhatsApp Business Cloud and use n8n instead. Build adaptable and scalable Development, Core Nodes, and Communication workflows that work with your technology stack. All within a building experience you will love.
How to connect Webhook and WhatsApp Business Cloud
- Step 1: Create a new workflow
- Step 2: Add and configure nodes
- Step 3: Connect
- Step 4: Customize and extend your integration
- Step 5: Test and activate your workflow
Step 1: Create a new workflow and add the first step
In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.
Step 2: Add and configure Webhook and WhatsApp Business Cloud nodes
You can find Webhook and WhatsApp Business Cloud in the nodes panel. Drag them onto your workflow canvas, selecting their actions. Click each node, choose a credential, and authenticate to grant n8n access. Configure Webhook and WhatsApp Business Cloud nodes one by one: input data on the left, parameters in the middle, and output data on the right.
Step 3: Connect Webhook and WhatsApp Business Cloud
A connection establishes a link between Webhook and WhatsApp Business Cloud (or vice versa) to route data through the workflow. Data flows from the output of one node to the input of another. You can have single or multiple connections for each node.
Step 4: Customize and extend your Webhook and WhatsApp Business Cloud integration
Use n8n's core nodes such as If, Split Out, Merge, and others to transform and manipulate data. Write custom JavaScript or Python in the Code node and run it as a step in your workflow. Connect Webhook and WhatsApp Business Cloud with any of n8n’s 1000+ integrations, and incorporate advanced AI logic into your workflows.
Step 5: Test and activate your Webhook and WhatsApp Business Cloud workflow
Save and run the workflow to see if everything works as expected. Based on your configuration, data should flow from Webhook to WhatsApp Business Cloud or vice versa. Easily debug your workflow: you can check past executions to isolate and fix the mistake. Once you've tested everything, make sure to save your workflow and activate it.
WhatsApp Starter Workflow
This n8n workflow is designed for working with the WhatsApp Business platform. It allows to send custom replies via WhatsApp in response to incoming user messages.
💡 Take a look at the step-by-step tutorial on how to create a WhatsApp bot.
The workflow consists of two parts:
- The first Verify webhook sends back verification challenge string. You will need this part during the setup process on the Meta for Developers portal:
- Select your App
- Go to WhatsApp Configuration
- Click on the Edit button in the Webhook session
- Enter your production webhook URL, provide Verify token (can be any text string)
- Remember to activate the n8n workflow!
- Finally press "Verify and save"
- Once the webhook is verified, the Respond webhook receives various POST requests from Meta regarding WhatsApp messages (user messages and status notifications).
The workflow checks whether the incoming JSON contains a user message. If this is the case, it sends the text message back to the user. This is a custom message, not a WhatsApp Business template.

Build your own Webhook and WhatsApp Business Cloud integration
Create custom Webhook and WhatsApp Business Cloud workflows by choosing triggers and actions. Nodes come with global operations and settings, as well as app-specific parameters that can be configured. You can also use the HTTP Request node to query data from any app or service with a REST API.
Webhook and WhatsApp Business Cloud integration details
Webhook
Webhooks are automatic notifications that apps send when something occurs. They are sent to a certain URL, which is effectively the app's phone number or address, and contain a message or payload. Polling is nearly never quicker than webhooks, and it takes less effort from you.
