Call POST API in Flows (Webhooks)

With the Call POST API node inside Chatarmin Flows, you can send data from Chatarmin to external tools such as Make.com, Zapier, n8n, or any other system that supports webhooks / API endpoints.

This allows you to connect Chatarmin with other platforms and automate processes across multiple systems.

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}

Summary

The Call POST API node is the best option if you want to build advanced automations and connect Chatarmin with external systems.

It enables seamless communication between tools by sending structured JSON data and triggering webhooks in platforms like Make.com, Zapier, n8n, and more.
