How to unsubscribe webhooks with http response status?

Our integration is receiving webhooks from Brevo users, who have stopped using our app long time ago. We dont have anymore access tokens to make requests to Brevo API on their behalf. So we cant delete the webhook subscriptions via API.

Is there any possibility to force those webhooks to unsubscribe by responding with specific http response code, like 400, 404, 410?

Hi there, thanks for your message!

Do you have a Brevo account? If so, and as your question is quite specific, could you please create a support ticket by sending an email to contact@brevo.com?

Thanks!
