Owner update in organization send many webhooks

Hello. I create webhook (organization update) and I catch the webhook with my symfony synchronization app. When I update organization owner, webhook sends me what i need but many times.
And the problem is: When the sales representative does not fill in everything we need in organization, Notes are inserted into the organization. But many send webhooks = many notes = mess on organization dashboard.
“many” mean 20x - 30x
and selecting according to the “retry parameter” will not help.
please help.
