Hi Community, I am currently in the process of creating a Webhook and the app I am accessing uses immediate confirmation which requires me to return a 200 code to confirm I want to receive Webhook notifications. How do i go about returning this 200 code? The app I am using sent a POST request to me with a random secret included in the header. It then wants me to return this secret as a header in a 200 code response. I do not understand how I return this 200 response code, do I need to use a HTTP request? Any help would be much appreciated! Thanks Everyone!

You need the webhook node using Response Mode: Last Entry. Connect the webhook node to a set node and return the secret in the format needed. You can also use a function node but the set node should be just fine. [image]

Hi Ricardo, Could I not use the header response option built into the webhook node? Or is that for something else Thanks

Ahh, on the header, I missed that. Sadly that is not possible. [image] Webhook - how to respond with data from incoming GET and POST Questions Ok … still struggling with this. Webhook comes in and has header param xxxxx with value"9885792nkdjnfskdj0395". I need to capture that value and pass it back in the response-header as parameter yyyyy. I can pass it back in the body but how do I set the header param and value in the response ?

I thought this was updated in the latest update of n8n

Do not see it in the changelog. Where did you see that? Release notes | n8n Docs Release notes detailing new features and bug fixes for n8n.

Yes, you can respond with a header but cannot reference the header dynamically, which is what you need to do. If the header were a fixed value, this would work.

Ahhh i understand. So currently there is no way for me to respond with a dynamic header?

Is there a way for me to send back the header in a different node? The webhook is open for 72 hours before becoming inactive so I wouldn’t need to send a response immediately.

Sadly not. At least not using only n8n.
