  'endpoint' => '...',
  'credential_key' => '...',
  'credential_secret' => '...',
  'notification_service_url' => '...',
  'method_add_trigger' => 'api/trigger',
  

Events

Usage

• Import the Notification class

  use GetPhoto\Notification;

• Pass the data to the method to push events

  (new Notification)->pushEvent($data);

• Examples

  • User Login

    $data = [
        'eventTypeId' => 'User.Login',
        'dateTime' => '20170117 232900',
        'userId' => '1',
        'photographerId' => '1',
    ];
    (new Notification)->pushEvent($data);

  • New Contactsheet

    $data = [
        'eventTypeId' => 'Contactsheet.Created',
        'dateTime' => '20170115 080005',
        'userId' => '5',
        'photographerId' => '2',
        'contactsheetId' => 'a0shfd0a9shf9',
    ];
    (new Notification)->pushEvent($data);

Triggers

Usage

• Import the Trigger class

  use GetPhoto\Trigger;

• Instantiate a new object, add the options and save

  //Trigger ID => Unique name for your trigger
  //Trigger type => EventBased, Scheduled, TimeBased or Manual
  //Trigger action => Action to be executed
  $trigger = new Trigger('trigger id', 'trigger description', 'trigger type', 'trigger action');
  
  //optional methods
  $trigger->addSubscriptionKey('value');
  $trigger->addDelay('value');
  $trigger->addWhen('value');
  
  //auxiliar methods
  $trigger->createActionParameterConstant('constant', 'value');
  $trigger->createActionParameterVariable('variable', 'value');
  $trigger->createActionParameterMethod('variable', 'method', ['arguments', ...]);
  
  //optional methods that can be used multiple times
  $trigger->addActionParameter($parameter);
  $trigger->addParameter(['data key' => 'data value', ...]);
  
  $trigger->save();

Samples

Manual Trigger

Triggers that are executed via api request

• Return a json with all login from an user

  Problem: We need a trigger to feed the user's config page with all of his logins. The config page will make an api request whenever the user request the login data.

  Solution: We have the method returnEvents which filter events based on given arguments. In this case, we want to filter by EventTypeId and UserId. We can obtain the UserId from the subscription, so it is a variable. Since we already know the EventTypeId, we define a constant.

  $trigger = new Trigger('UserLogins.v1', 'Shows all logins from an user', 'Manual', 'method::returnJson');
  $trigger->addSubscriptionKey('UserId');
  
  $userId = $trigger->createVariable('userId', 'userId');
  $eventTypeId = $trigger->createConstant('eventTypeId', 'User.Login');
  $eventsMethod = $trigger->createMethod('returnJson', [$userId, $eventTypeId]);
  $events = $trigger->createVariable('events', $eventsMethod);
  
  $trigger->addActionParameter($events);
  $trigger->save();

  Result:

  • Trigger ID: UserLogins.v1
  • Trigger Description: Shows all logins from an user
  • Type: Manual
  • Subscription Key: UserId
  • Action: method::returnJson
  • Action Parameters: events::{{returnEvents||userId::[[userId]]||eventTypeId::User.Login}}
