Bitrix24 Bot Platform

When installing and updating the application, 2 events are used: ONAPPINSTALL and ONAPPUPDATE. Both events has the same set of data, with only one different parameter - [PREVIOUS_VERSION] => 1, where old version of the app is specified.

ONAPPINSTALL event for installation of the application

[data] => Array(
  [LANGUAGE_ID] = com // Account basic language
  [VERSION] = 1 // Application version
)
[auth] => Array(
    [access_token] => lh8ze36o8ulgrljbyscr36c7ay5sinva // Key to send request to REST service
    [scope] => imbot // Permitted access levels 
    [domain] => b24.hazz // Bitrix24 domain account, on which the application is installed
    [application_token] => c917d38f6bdb84e9d9e0bfe9d585be73 // Application token will help you to "fend off" redundant requests to event handler; this field is available in all events

    [expires_in] => 3600 // Token expiration period, after which new token will have to be requested
    [member_id] => d41d8cd98f00b204e9800998ecf8427e // Unique account ID, required to extend authentication
    [refresh_token] => 5f1ih5tsnsb11sc5heg3kp4ywqnjhd09 // Key to extend authentication
)
