Could you help me or if you can share how to connect from the Meta Business to be able to make the connection. I have tried several ways, generate the API in Meta, connect it to a number to receive messages and when I send messages nothing arrives to N8N to the On message trigger.
It looks like your topic is missing some important information. Could you provide the following if applicable.
- n8n version:
- Database (default: SQLite):
- n8n EXECUTIONS_PROCESS setting (default: own, main):
- Running n8n via (Docker, npm, n8n cloud, desktop app):
- Operating system:
Thanks for posting here and welcome to the community! 
There could be a factor of things to check to debug this. Have you checked that your workflow is active and you’re using the prod webhook url? If you’re self-hosting, have you set up your URL with WEBHOOK_URL ?
Can you please share your workflow to see your config? Are you getting any errors?
Tip for sharing your workflow in the forum
Pasting your n8n workflow
Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.
```
<your workflow>
```
Make sure that you’ve removed any sensitive information from your workflow and include dummy data or pinned data as much as you can!
