Send WhatsApp Templated Messages Using Ruby


This guide shows how to send a templated WhatsApp message to any destination WhatsApp number. Templated messages are crucial to your WhatsApp messaging experience, as businesses can only initiate WhatsApp conversations using templated messages. 

You can start sending templated WhatsApp messages using our APIs. Follow these instructions.


To get started, you need a Plivo account — sign up with your work email address if you don’t have one already. If this is your first time using Plivo APIs, follow our instructions to set up a Ruby development environment.

Once you have a Plivo account, follow our WhatsApp guide to onboard your WhatsApp account, register a number against your WABA, and have a template in an approved state.

If your phone number is in connected state and a template is in approved state, you can send your first message.

Create the send WhatsApp application

Create a file called WhatsappMessageCreate.rb and paste into it this code.

"require "plivo"
include Plivo

api ="<auth_id>","<auth_token>")

            "name": "sample_purchase_feedback",
            "language": "en_US",
            "components": [
                    "type": "header",
                    "parameters": [
                            "type": "media",
                            "media": ""
                    "type": "body",
                    "parameters": [
                            "type": "text",
                            "text": "Livpure Water Purifier"

response = api.messages.create(
        src: "+14151112221",
        url: "https://<yourdomain>.com/sms status/",
puts response
#Prints only the message_uuid
puts response.message_uuid"

Replace the auth placeholders with your authentication credentials from the Plivo console. Replace the phone number placeholders with actual phone numbers in E.164 format (for example, +12025551234). src should be your phone number registered against your WhatsApp Business Account. dst should be the destination WhatsApp number that you want to receive the message. 

WhatsApp templates support four components: header, body, footer, and buttons. When you send messages, the template object you see in the code acts as a way to pass the dynamic parameters. header  can accommodate text or media (images, video, documents) content. body  can accommodate text content. footer  cannot have any dynamic variables. Plivo does not support sending dynamic parameters in buttons yet. 

Note: We recommend that you store your credentials in the auth_id and auth_token environment variables to avoid the possibility of accidentally committing them to source control. If you do this, you can initialize the client with no arguments and Plivo will automatically fetch the values from the environment variables. You can use process.env to store environment variables and fetch them when initializing the client.


Save the file and run it.

$ WhatsappMessageCreate.rb
Note: If you’re using a Plivo Trial account, you can send messages only to phone numbers that have been verified with Plivo. You can verify (sandbox) a number by going to the console’s Phone Numbers > Sandbox Numbers page.
