@AnandBhagwatSame exact thing here. For sure there was something going on with the system that was delaying or impeding webhooks from hitting endpoints. It is extremely rare. There has hardly been a week go by for the past 9 months that I don’t run at least one test transaction, and in my development phase I will often run dozens in one day to test new functionality. I run all my test on a remote server that is configured to receive webhooks. I cannot count how many times I have deleted all the records of my customers, orders, items, etc tables due to the list being too massive to deal with. I’m at over 1,500 webhooks received, and 99.5% come back within 5 seconds of hitting the pay button.
I was working with a different and newer client when this issue first came up. So after a while I switched to my heavily vetted preexisting test site url. I ran two transactions and it took over an hour for them to come back. That was at about 8 pm yesterday. After those 2 came back, things started being business as usual immediately, with instant responses.
The day before they were “down” intermittently. On and off again you would get an instant response. Like I say, first issue like this ever in going on 9 or 10 months of continuous testing.
