How to integrate 2 Bitrix without transferring common users and BP, only sending tasks?

Question

Bitrix24

The accountant and HR will be one for the 2nd company. And BP will be started in Portal1, and an employee of Portal2 should receive a task / task.
How can I implement the synchronization of 2 portals, sending tasks / tasks from the BP of Portal1 to Portal2?

Answer 1

First of all, let's deal with the terminology: Task and task are different entities in the system.
A task is a specific step of a business process that is generated when a business process is started, i.e. apart from the business process, the task does not exist. Even two identical business processes do not generate the same task. Therefore, it is impossible to "rummage" tasks between portals.
From the point of view of the problem being solved, there are the following ways to achieve it
: if portal users will be external users. In this case, between two cloud portals, this scheme can work.
The Bitrix24 product (boxed version) does not provide such features. That is: you cannot set cross-portal tasks if at least one of the portals is boxed. To implement "sharing" of tasks, you can use the API, but with limitations:
- In the REST-api, you cannot transfer files and you will have to support mapping tables on one of the boxed sides
- If we are talking about php code, then you can implement everything there, but the mechanic will have to implement a sufficiently large number.
We tried to make task synchronization between the box and the cloud, but nothing good came of it. Too few api features and too many pitfalls and mechanics.

Answer 2

there is an API for such solutions
