How to transfer the transaction id from the Bitrix 24 crm embedded application?

Question

1C-Bitrix

Hello everyone
Created a local embedded application in Bitrix CRM.
Built into a deal using the CRM_DEAL_LIST_MENU method The
question is how, when you click on the application button from a deal, pass the id of this deal? Get or Post doesn't matter

Answer 1

When the application is opened, $_REQUEST flies from the embedding place to the handler, which contains the PLACEMENT => CRM_DEAL_LIST_MENU (embedding location) and PLACEMENT_OPTION => {"ID":"123"} (element id) parameters.
More details here: https://dev.1c-bitrix.ru/learning/course/index.php...
There is also a method in the JS library BX24.placement.info() - it also returns the embedding place and ID.

Answer 2

Registered the field through "userfieldtype.add" unfortunately there is no PLACEMENT in $__REQUEST, and the BX24.placement.info() method returns null what could be the reason? anyone have a solution for this problem?
