How it integrates

An API built to integrate with real processes

Gama CRM exposes an integration layer so your applications can trigger sends, use templates and check results without depending on a human interface for every operation.

1

Authenticate

Use an API Key associated with the account that will send the message.

2

Send

Post text, a template, or compatible content to the relevant endpoint.

3

Check status

Retrieve the message status to feed into your own business flow.

Sending a template Sample request
POST /api/public/messages
x-api-key: YOUR_API_KEY
Content-Type: application/json

{
  "to": "50688888888",
  "type": "template",
  "template": {
    "name": "confirmacion_solicitud",
    "language": "en",
    "components": [
      { "type": "body", "parameters": [
        { "type": "text", "text": "Mauricio Ulate" }
      ]}
    ]
  }
}

Use cases

Useful whenever WhatsApp is part of a bigger process

The integration becomes valuable when a message turns into a business action: notifying, reminding, confirming, requesting or logging an interaction.

  • Payment or due-date reminders from an administrative system.
  • Invoice, order or payment confirmations from a billing platform.
  • Alerts, follow-up or support from a CRM, ERP or internal portal.

Typical flow

Internal event
Your system detects a condition, for example an invoice issued or an upcoming due date.
API request
The system calls the Gama CRM API with the account and message type to use.
Follow-up
Your application checks the message status to log evidence or continue the process.
