# Documentation changes for November 5, 2026

As part of an ongoing effort to better align the documentation with the API, we've documented a boarding owner field. This change affects the documentation only; the API was already accepting and returning this data.

## Documented `primaryOwner` on boarding owner records

Documented `primaryOwner`, a nullable boolean on owner records (`ownership` items in requests, `ownerData` / `OwnerData` items in responses). Set it to `true` on one owner to mark them as the primary owner, the main principal that Payabli sends to the processor. If you flag more than one owner, the request fails with HTTP 400. If the application has one owner and you don't flag it, Payabli flags that owner. When you update an application and send `ownership`, set `primaryOwner` again.

This affects the following endpoints:

* [Create merchant application](/developers/api-reference/boarding/create-boarding-application)
* [Update app](/developers/api-reference/boarding/update-boarding-application)
* [Get boarding application by ID](/developers/api-reference/boarding/get-boarding-application-by-id)
* [Get application via auth token](/developers/api-reference/boarding/get-boarding-application-by-auth)
* [List applications for an organization](/developers/api-reference/boarding/get-list-of-applications-for-an-organization)
