Introduction

In this tutorial, you'll learn how to send messages to phone numbers stored in a CSV file using Ruby and the PulpoChat API. We will read the phone numbers and messages from the CSV file, and then send them using the PulpoChat API.

This article is just a small taste of all the API features. Explore dozens of use cases and ready-to-use code examples here.

Prerequisites

Install required packages

First, create a new directory for your project and navigate to it in your terminal. Then, run the following command to install the necessary libraries:

gem install httparty csv

Create the CSV file

Create a new file named numbers.csv in your project directory with two columns:

  1. First column: phone number in E164 format with the country prefix.
  2. Second column: text message to send to the target phone number.

The spreadsheet document should look like this:

Phone number Message body
+1234567890 👋 Welcome to {{your-business-name}}! Thanks for signing up. We are just a message away!
+1234567890 💐 Your order has been shipped. Tracking number is {{tracking-number}}. Don't hesitate to reach out to if you need help! 🤗

The equivalent spreadsheet document exported as CSV should look like this:

+1234567890,"👋 Welcome to {{your-business-name}}! Thanks for signing up. We are just a message away!"
+1234567890,"💐 Your order has been shipped. Tracking number is {{tracking-number}}. Don't hesitate to reach out to if you need help! 🤗"

Create a file with the code

Create a new file named send_messages.rb in your project directory and add the following code:

require 'httparty'
require 'csv'

csv_file = 'numbers.csv'

# Replace this with your PulpoChat API token
# Get your API token here: https://app.pulpo.chat/apikeys
api_token = 'ENTER API KEY HERE'

# Optionally specify the target WhatsApp device ID connected to PulpoChat
# you want to use for messages delivery (24 characters hexadecimal value)
device = 'DEVICE ID GOES HERE'

headers = {
  'Content-Type': 'application/json',
  'Authorization': api_token
}

url = 'https://api.pulpo.chat/v1/messages'

def send_message(phone, message)
  body = {
    phone: phone,
    message: message,
    device: device
  }
  response = HTTParty.post(url, body: body.to_json, headers: headers)
  if response.code == 200
    puts "=> Message created: #{phone}"
  else
    puts "Failed to create message to #{phone}: #{response.body}"
  end
end

CSV.foreach(csv_file) do |row|
  phone, message = row
  send_message(phone, message)
end

Replace the API token

In the send_messages.rb file, make sure you have defined the API token of your actual PulpoChat account:

# Replace this with your PulpoChat API token
api_token = 'ENTER API KEY HERE'

Optionally, if you have multiple WhatsApp numbers connected in your PulpoChat account, you can specify which WhatsApp number you want to use for the messages delivery by specifying the PulpoChat unique device ID (24 characters hexadecimal value) in the following line:

// Optionally specify the target WhatsApp device ID connected to PulpoChat
// you want to use for messages delivery (24 characters hexadecimal value)
device = 'DEVICE ID GOES HERE'

Run the program

Before running the program, if you plan to send hundreds of messages in a row, we recommend to define a lower messages delivery speed per minute no more than 2-3 messages per minute to prevent ban issues due to anti-spam policies by WhatsApp. Learn more about best practices and how to reduce risk here.

Open a terminal in your projectdirectory and run the following command to execute the send_messages.rb script:

ruby send_messages.rb

If everything is set up correctly, you should see output indicating the messages have been created successfully:

=> Message created: +1234567890
=> Message created: +1234567890
=> Message created: +1234567890

Note messages will be added to your number's message delivery queue and delivered asynchronously in background over time based on your number's subscription message delivery speed per minute limit or the manually configured delivery speed you have defined in your number's settings.

Messages may take several minutes or hours, depending on how much you have created, to be effectively delivered to the target phone numbers via WhatsApp. You can monitor the progress of the messages delivery in the web panel or automatically by using webhook events.

Conclusion

In this tutorial, you learned how to send messages to phone numbers stored in a CSV file using Ruby, the httparty library, and the PulpoChat API.

You can update the numbers.csv file and run the program again anytime you want to send new messages through your PulpoChat connected WhatsApp number.

You can further customize the script to handle additional columns, create different types of messages, or integrate it with your own software as needed.
