Describe the problem/error/question

Hello guys,
Im using a webhook node. When I send the request to it (Production or test) it receives the body twice or 3 times on 1 click.
How can I fix it so that It receives the data only once?

What is the error message (if any)?

@Nazih_Saba , I wonder if the service that sends the request to your webhook expects some specific response. As it does not get it, it might be re-sending the request assuming the webhook did not receive it.

@Nazih_Saba If you refresh the frontend, can you still reproduce the issue?
I’m wondering if this is an issue of the frontend listening to backend messages multiple times.

I think that was the issue. I modified the webhook to send response immediately, and so far the problem did not appear.

I thought the issue was with the frontend. But My worfklow posts data at specific places, and It was posting them multiple times on 1 click.
