How to Send WhatsApp API using Ruby

Introduction to WhatsApp API with Ruby

In this tutorial, we will create simple examples to send messages using WhatsApp API using Ruby.

Initially, you must make sure that the net/http library is ready Because we will use this library In this article to send messages to the Ultramsg Gateway.

First WhatsApp message using Ruby

require 'uri'
require 'net/http'
require 'openssl'

url = URI("https://api.ultramsg.com/instance1316/messages/chat")

http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Post.new(url)
request["content-type"] = 'application/x-www-form-urlencoded'
request.body = "token=5v941eyo9eqixrsi&to=14155552671&body=WhatsApp API on UltraMsg.com works good&priority=10&referenceId="

response = http.request(request)
puts response.read_body

When the previous code is executed, and if the message is sent successfully, the response will be like this:

{"sent":"true","message":"ok","id":47}

require 'uri'
require 'net/http'
require 'openssl'

http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Post.new(url)
request["content-type"] = 'application/x-www-form-urlencoded'
request.body = "token=5v941eyo9eqixrsi&to=14155552671&image=https://file-example.s3-accelerate.amazonaws.com/images/test.jpg&caption=image Caption&referenceId="

response = http.request(request)
puts response.read_body
