About a whatsapp automation.
When it's the other way around, it's easy with an external request and a webhook, but in this case, I can't find any useful trigger in ManyChat.
How can I make n8n trigger an automation for whatsapp messaging?

Hi,
For that, you’ll have to use Manychat’s API to send a specific flow to a new or existing contact = https://api.manychat.com/swagger
But there’s a catch... 😂
The /sendFlow endpoint needs the subscriber_id. To get it, you need to search for existing contacts before creating a new one (if the contact already exists, you get an error message). And the only way to get it done with a WhatsApp ID is creating a custom field and an extra automation that populates this field with the contact’s WhatsApp phone number. Then you use the /findByCustomField endpoint to get the subscriber_id if it already exists.
That requires to create the custom field and an extra automation to populate the field once a new contact is created in Manychat.
On n8n’s side, it will just need 3 nodes to do all the work:
- Tries to create a new Subscriber.
- If there’s no contact with that WhatsApp number, it creates a new contact and returns the subscriber_id in the response.
- If a contact with the WhatsApp number already exists, you get an error
- If you get an error, the next node searches for the contact with that WhatsApp Number and gets the subscriber_id as response.
- Uses the /sendFlow endpoint to send the automation with the messages you selected to the new/existing contact.
If you need some help with that, feel free to send me a message. 😉

In ManyChat, n8n cannot directly trigger WhatsApp automations because ManyChat only supports triggers from incoming messages or user actions. To work around this, I would use ManyChat’s API or an external webhook. From n8n, I can send a request to ManyChat’s API to start the automation for the user or segment I want.
