Why use Call POST API?
You can use this node to:- Trigger workflows in Make, Zapier, or n8n
- Send customer data to CRMs
- Create tasks or tickets in external tools
- Sync contact data between systems
- Track events (e.g. conversions, support escalations, booking requests)
How it works
The Call POST API node sends a POST request to any URL you define (e.g. a webhook URL from Make.com). Inside the request body, you can send data in JSON format, such as:- Customer phone number
- Name
- Ticket ID
- Tags
- Custom fields
Sending data via JSON
In the node configuration, you can define a JSON body and include dynamic variables (properties) from Chatarmin. Example JSON payload:{ "phone": "{{contact.phone}}", "firstname": "{{contact.firstname}}", "tags": "{{contact.tags}}" }
Available contact properties
When setting up the JSON body, you can click the info (i) icon inside the node. There you will find a list of standard Chatarmin contact properties that can be used directly in flows, such as: Contact properties:Phone → {contact.phone} Email → {contact.email} Firstname → {contact.firstname} Lastname → {contact.lastname} Date Added → {contact.added} Tags → {contact.tags} Source → {contact.source} Consent → {contact.consent} Buttons clicked → {contact.clicked} Chat messages → {chat.messages} Previous message → {chat.previousMessage}
