We are changing how deals, leads and projects can be linked to activities.

What is changing?

At the moment when creating or updating an activity via Public API it is possible to link it with a deal, lead and a project at the same time.

After the changes are applied, it will only be possible to link an activity to one of the mentioned entities at once. The change affects the following 2 endpoints:

• POST /v1/activities
• PUT /v1/activities/{id}

It means that an activity can only be linked either to a deal, lead or a project.

If passing several of the mentioned entities in the payload the following hierarchy for linking will be used:

• If deal_id is passed together with lead_id or project_id the activity will be only linked to the deal
• If lead_id is passed together with project_id the activity will be only linked to the lead

What is changing?

Activities have always been intended to work like this but this limitation has never been implemented in our public API. This brings confusion for our users because Pipedrive UI has been built considering this limitation.
