Hey HunkyBill, thanks for your input. Considering my other problem with trying to respond as quick as possible to shopify, the first sniff would add time to processing. Even it only is 50 miliseconds, still added time :)
We did do that just as you suggested as I think you are ultimately correct. 24 calls later, they still come. However that's not a real issue since the calls are basically ignored from now on and just add bytes to our logs.
The other one though .... The order/create calls still come, we constantly respond with 200 in less then a second. I am very worried about them as I am sure the webhook will get deleted so I am now 100% I am missing something.
Should I add something more to my output then just "Allok" ? Should I output the content type to something specific? Content Encoding ?
The documentation on this issue simply says
"Your webhook acknowledges that it received data with a 200 OK response. Any response outside of the 200 range will let Shopify know that you did not receive your webhook. "
