The `facebook` notification platform enables sending notifications via Facebook Messenger, powered by [Facebook](https://facebook.com).
|
|
|
|
To use this notification platform in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
notify:
|
|
- name: NOTIFIER_NAME
|
|
platform: facebook
|
|
page_access_token: FACEBOOK_PAGE_ACCESS_TOKEN
|
|
```
|
|
|
|
Configuration variables:
|
|
|
|
- **page_access_token** (*Required*): Access token for your Facebook page. Checkout [Facebook Messenger Platform](https://developers.facebook.com/docs/messenger-platform/guides/setup) for more information.
|
|
- **name** (*Optional*): Setting the optional parameter `name` allows multiple notifiers to be created. The default value is `notify`. The notifier will bind to the service `notify.NOTIFIER_NAME`.
|
|
|
|
### {% linkable_title Usage %}
|
|
|
|
With Facebook notify service, you can send your notifications to your Facebook messenger with help of your Facebook page. You have to create a [Facebook Page and App](https://developers.facebook.com/docs/messenger-platform/guides/quick-start) for this service. You can control it by calling the notify service [as described here](/components/notify/). It will send a message on messenger to user specified by **target** on behalf of your page. See the [quick start](https://developers.facebook.com/docs/messenger-platform/guides/quick-start) guide for more information.
|
|
The phone number used in **target** should be registered with Facebook messenger. Phone number of the recipient should be in +1(212)555-2368 format. If your app is not approved by Facebook then the recipient should by either admin, developer or tester for your Facebook app. [More information](https://developers.facebook.com/docs/messenger-platform/send-api-reference#phone_number) about the phone number.
|
|
|
|
```yaml
|
|
# Example automation notification entry
|
|
automation:
|
|
- alias: Evening Greeting
|
|
trigger:
|
|
platform: sun
|
|
event: sunset
|
|
action:
|
|
service: notify.facebook
|
|
data:
|
|
message: 'Good Evening'
|
|
target:
|
|
- '+919413017584'
|
|
- '+919784516314'
|
|
```
|
|
|
|
You can also send messages to users that do not have stored their phone number with Facebook, but this requires a bit more work. The Messenger platform uses page specific user IDs instead of a global user ID. You will need to enable a webhook for the "messages" event in Facebook's developer console. Once a user writes a message to a page, that webhook will then receive the user's page specific ID as part of the webhook's payload. Below is a simple PHP script that reacts to the message "get my id" and sends a reply containing the user's ID:
|
|
|
|
```php
|
|
<?php
|
|
|
|
$access_token = "";
|
|
$verify_token = "";
|
|
|
|
if (isset($_REQUEST['hub_challenge'])) {
|
|
$challenge = $_REQUEST['hub_challenge'];
|
|
$hub_verify_token = $_REQUEST['hub_verify_token'];
|
|
|
|
if ($hub_verify_token === $verify_token) {
|
|
echo $challenge;
|
|
}
|
|
}
|
|
|
|
$input = json_decode(file_get_contents('php://input'), true);
|
|
$sender = $input['entry'][0]['messaging'][0]['sender']['id'];
|
|
$message = $input['entry'][0]['messaging'][0]['message']['text'];
|
|
|
|
if (preg_match('/get my id/', strtolower($message))) {
|
|
$url = 'https://graph.facebook.com/v2.10/me/messages?access_token=' . $access_token;
|
|
$ch = curl_init($url);
|
|
$jsonData = '{
|
|
"recipient":{
|
|
"id":"' . $sender . '"
|
|
},
|
|
"message":{
|
|
"text":"Your ID: ' . $sender . '"
|
|
}
|
|
}';
|
|
|
|
$jsonDataEncoded = $jsonData;
|
|
curl_setopt($ch, CURLOPT_POST, 1);
|
|
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);
|
|
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
|
|
|
|
if (!empty($input['entry'][0]['messaging'][0]['message'])) {
|
|
$result = curl_exec($ch);
|
|
}
|
|
}
|
|
|
|
```
|
|
|
|
### {% linkable_title Rich messages %}
|
|
You could also send rich messing (cards, buttons, images, videos, etc). [Info](https://developers.facebook.com/docs/messenger-platform/send-api-reference) to which types or messages and how to build them.

|
