ANNEX: Additional options in Messages

In this annex you will learn how to send messages from your templates. WhatsAPP templates allow you to send more elaborate messages than text messages, allowing you to attach files, as well as include buttons in your messages.

Options

The options allow you to send interactive messages, attach images, videos, documents and share locations via WhatsApp. To do this, here you will learn how to customize the "options" parameter. The "options" parameter must be a string in JSON format following the following specifications:

Main parameters
header Details about the message header (optional)
params Values to the different values of the template (optional)
Example
{"header":"", "params": ""}
