Ruby Whatsapp SDK

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.

Option 1) Use an initializer

# 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

Notes:

Optionally, you can specify the desired API version to use (defaults to the latest version if omitted). Available API version can be found here.
You can attach a logger. More Details on Faraday Logger Options are here.

Option 2) Create a `Client` instance :

# without
client = WhatsappSdk::Api::Client.new("<ACCESS TOKEN>") # replace this with a valid access token

# OR optionally use a logger, api_version and
logger = Logger.new(STDOUT)
logger_options = { bodies: true }
client = WhatsappSdk::Api::Client.new("<ACCESS TOKEN>", "<API VERSION>", logger, logger_options)

Set up a Meta app

1) Create a Meta Business app

2) Add Whatsapp to your Application

3) Add a phone number to your account

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

5) Use the GEM to interact with Whatsapp

Example:

Install the gem by running gem install whatsapp_sdk in the gem.
Open the irb terminal by running irb
require "whatsapp_sdk"
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

Configure the Client by running

WhatsappSdk.configure do |config|
  config.access_token = ACCESS_TOKEN
end

Try the Phone Numbers API or Messages API

Phone Numbers API

registered_number = client.phone_numbers.registered_number(SENDER_ID)

Messages API

message_sent = client.messages.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.

Sneak Peek

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

client.phone_numbers.register_number(SENDER_ID, 123456) # register the phone number to uplaod media and send message from.

# send a text and a location
client.messages.send_text(sender_id: SENDER_ID, recipient_number: RECIPIENT_NUMBER,message: "Hey there! it's Whatsapp Ruby SDK")

client.messages.send_location(sender_id: SENDER_ID, recipient_number: RECIPIENT_NUMBER, longitude: -75.6898604, latitude: 45.4192206, name: "Ignacio", address: "My house")

# upload a photo and send it
image = client.media.upload(sender_id: SENDER_ID, file_path: "test/fixtures/assets/whatsapp.png", type: "image/png")image = client.media.get(media_id: uploaded_media.id)
client.messages.send_image(sender_id: SENDER_ID, recipient_number: RECIPIENT_NUMBER, image_id: image.id)

# upload a sticker and send it
sticker = client.media.upload(sender_id: SENDER_ID, file_path: "test/fixtures/assets/sticker.webp", type: "image/webp")
client.messages.send_sticker(sender_id: SENDER_ID, recipient_number: RECIPIENT_NUMBER, sticker_id: sticker.id)

Errors

If the API returns an error then an exception WhatsappSdk::Api::Responses::HttpResponseError is raised. The object contains information returned by the Cloud API. For more information about the potential error check the official documentation.

Examples

Visit the example file with examples to call the API in a single file.

Whatsapp Cloud API

See the official documentation for the Whatsapp Cloud API.
For pricing, refer to the official documentation. As of today, Whatsapp offers have 1000 conversations free per month.

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.
