Repository Details

A lightweight, efficient Ruby gem for interacting with Whatsapp Cloud API.

Ruby Whatsapp SDK

Gem Version CircleCI

The SDK provides a set of operations and classes to use the Whatsapp API. Send stickers, messages, audio, videos, locations, react and reply to messages or just ask for the phone numbers through this library in a few steps!

Demo

MessageAPIDemo.mov

Check the Ruby on Rails Whatsapp example repository that uses this library to send messages.

Installation

Add this line to your application's Gemfile:

gem 'whatsapp_sdk'

And then execute:

$ bundle

Or install it yourself as:

$ gem install whatsapp_sdk

Quick Start

There are three primary resources, Messages, Media and PhoneNumbers. Messages allows users to send any message (text, audio, location, video, image, etc.). Media allows users to manage media, and Phone Numbers enable clients to query the associated phone numbers.

To use Messages, Media or PhoneNumbers, you need to initialize the Client that contains auth information. There are two ways to do it.

  1. Use an initializer

Note: Optionally, you can specify the desired API version to use (defaults to the latest version if omitted). Available API version can be found here.

# config/initializers/whatsapp_sdk.rb
WhatsappSdk.configure do |config|
  config.access_token = ACCESS_TOKEN
  config.api_version = API_VERSION
  config.logger = Logger.new(STDOUT) # optional, Faraday logger to attach
  config.logger_options = { bodies: true } # optional, they are all valid logger_options for Faraday
end

More Details on Faraday Logger Options are here.

OR 2) Create a Client instance and pass it to the Messages, Medias or PhoneNumbers instance like this:

Without Logger:

client = WhatsappSdk::Api::Client.new("<ACCESS TOKEN>") # replace this with a valid access token
messages_api = WhatsappSdk::Api::Messages.new(client)

With Logger:

logger = Logger.new(STDOUT)
logger_options = { bodies: true }
client = WhatsappSdk::Api::Client.new("<ACCESS TOKEN>", "<API VERSION>", logger, logger_options) # replace this with a valid access token
messages_api = WhatsappSdk::Api::Messages.new(client)

Each API operation returns a WhatsappSdk::Api::Response that contains data and error and a couple of helpful functions such as ok? and error?. There are three types of responses WhatsappSdk::Api::MessageDataResponse, WhatsappSdk::Api::PhoneNumberDataResponse and WhatsappSdk::Api::PhoneNumbersDataResponse. Each of them contains different attributes.

Set up a Meta app

1) Create a Meta Business app Screen Shot 2022-09-05 at 11 03 47 AM
2) Add Whatsapp to your Application Screen Shot 2022-09-05 at 11 05 43 AM
3) Add a phone number to your account Screen Shot 2022-09-05 at 11 09 22 AM

Try sending a message to your phone in the UI.

4) Copy the ACCESS_TOKEN, the SENDER_ID, the BUSINESS_ID and the RECIPIENT_NUMBER Screen Shot 2022-09-05 at 11 13 24 AM
5) Use the GEM to interact with Whatsapp

Example:

  1. Install the gem by running gem install whatsapp_sdk in the gem.
  2. Open the irb terminal by running irb
  3. require "whatsapp_sdk"
  4. Set up the ACCESS_TOKEN, the SENDER_ID, the BUSINESS_ID and the RECIPIENT_NUMBER in variables.
ACCESS_TOKEN = "EAAZAvvr0DZBs0BABRLF8zohP5Epc6pyNu"
BUSINESS_ID = 1213141516171819
SENDER_ID = 1234567891011
RECIPIENT_NUMBER = 12398765432
  1. Configure the Client by running
WhatsappSdk.configure do |config|
  config.access_token = ACCESS_TOKEN
end
  1. Try the Phone Numbers API or Messages API

Phone Numbers API

phone_numbers_api = WhatsappSdk::Api::PhoneNumbers.new
registered_number = phone_numbers_api.registered_number(SENDER_ID)

Messages API

messages_api = WhatsappSdk::Api::Messages.new
message_sent = messages_api.send_text(sender_id: SENDER_ID, recipient_number: RECIPIENT_NUMBER,
                                      message: "Hey there! it's Whatsapp Ruby SDK")

Check the example.rb file for more examples.

Operations

First, create the client and then create an instance WhatsappSdk::Api::Messages that requires a client as a param like this:

messages_api = WhatsappSdk::Api::Messages.new
phone_numbers_api = WhatsappSdk::Api::PhoneNumbers.new
medias_api = WhatsappSdk::Api::Medias.new
business_profile_api = WhatsappSdk::Api::BusinessProfile.new
templates_api = WhatsappSdk::Api::Templates.new

Note: Remember to initialize the client first!

APIs

Templates

# Get list of templates
templates_api.templates(business_id: BUSINESS_ID)

Phone numbers API

Get the list of phone numbers registered

phone_numbers_api.registered_numbers(123456) # accepts a business_id

Read a message

messages_api.read_message(sender_id: 1234, message_id: "wamid.HBgLMTM0M12345678910=")

Note: To get the message_id you can set up Webhooks that will listen and fire an event when a message is received.

Send a reaction to message To send a reaction to a message, you need to obtain the message id and look for the emoji's unicode you want to use.

messages_api.send_reaction(sender_id: 123_123, recipient_number: 56_789, message_id: "12345", emoji: "\u{1f550}")

messages_api.send_reaction(sender_id: 123_123, recipient_number: 56_789, message_id: "12345", emoji: "⛄️")

Reply to a message To reply to a message, just include the id of the message in the messages_api methods. For example, to reply to a text message include the following:

messages_api.send_text(sender_id: 123_123, recipient_number: 56_789, message: "I'm a reply", message_id: "wamid.1234")

contacts = [create_contact(params)]
messages_api.send_contacts(sender_id: 123123, recipient_number: 56789, contacts: contacts)

Alternatively, you could pass a plain json like this:

Send a template message WhatsApp message templates are specific message formats that businesses use to send out notifications or customer care messages to people that have opted in to notifications. Messages can include appointment reminders, shipping information, issue resolution or payment updates.

Before sending a message template, you need to create one. visit the Official API Documentation

Whatsapp Cloud API

Troubleshooting

If you try to send a text message directly without a message template created and approved in your Meta control panel, you can't start a chat with other people. But if you receive a message before, it's possible to send a message.

If the API response is still success, but the message is not delivered:

  • ensure the device you're sending the message to is using a supported Whatsapp version. Check documentation. Try also replying a message to the number you are registered on your Whatsapp.
  • Ensure your Meta App uses an API version greater than or equal to v.14.
  • Ensure that the Panel in the Facebook dashboard doesn't display any errors.

Note: Sometimes the messages are delayed; see Meta documentation.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests.

Run ' bundle exec rake install ' to install this gem onto your local machine. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Run all the tests

  • Unit tests: Run rake test
  • Sorbet Typecheck: run srb tc
  • Linters: bundle exec rubocop

To update the Cloud API version update the version in lib/whatsapp_sdk/api/api_configuration.rb. Check the Cloud API changelog for API udpates.
