What is changing?

During the webhook creation via API, all non-reserved fields were stored as part of the webhook “additional_data” object and sent in the API request response.

Starting from March 4th, this field will be removed from the webhooks API responses.

Why is it changing?

“additional_data” is a legacy field that isn’t used in the webhook payloads delivery, which slows down events processing. Removing it from the webhooks configuration body will improve system performance and stability.
