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

**Check the [Ruby on Rails Whatsapp example repository](https://github.com/ignacio-chiazzo/ruby_on_rails_whatsapp_example)** that uses this library to send messages.

## Installation

Add this line to your application's Gemfile:

```ruby
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

```ruby
# 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](https://developers.facebook.com/docs/graph-api/changelog/versions).
- You can attach a logger. More Details on Faraday Logger Options are [here](https://lostisland.github.io/faraday/#/middleware/included/logging?id=logging).


#### Option 2) Create a `Client` instance :

```ruby

# 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)
```

<details><summary>5) Use the GEM to interact with Whatsapp</summary>

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.

```ruby
ACCESS_TOKEN = "EAAZAvvr0DZBs0BABRLF8zohP5Epc6pyNu"
BUSINESS_ID = 1213141516171819
SENDER_ID = 1234567891011
RECIPIENT_NUMBER = 12398765432
```

5. Configure the Client by running

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

6. Try the Phone Numbers API or Messages API

Phone Numbers API

```ruby
registered_number = client.phone_numbers.registered_number(SENDER_ID)
```

Messages API

```ruby
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](https://github.com/ignacio-chiazzo/ruby_whatsapp_sdk/blob/main/example.rb) for more examples.

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")

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

### 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](https://developers.facebook.com/docs/whatsapp/cloud-api/support/error-codes/).

## Examples

Visit [the example file](/example.rb) with examples to call the API in a single file.

## Whatsapp Cloud API

- See the [official documentation](https://developers.facebook.com/docs/whatsapp/cloud-api) for the Whatsapp Cloud API.
- For pricing, refer to the [official documentation](https://developers.facebook.com/docs/whatsapp/pricing/). 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](https://developers.facebook.com/docs/whatsapp/cloud-api/support/troubleshooting#message-not-delivered). 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](https://developers.facebook.com/docs/whatsapp/on-premises/guides/send-message-performance#delays).

## 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](https://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](https://developers.facebook.com/docs/whatsapp/business-platform/changelog#api-error-response-behavior).
