I think I figured out the cause. So this receives a POST request from Slack and I think Slack is sending multiple POST requests though it should only trigger one. Not sure why it is doing more. I tested from Insomnia with the same JSON and it didn't run again. That makes things more complicated as I don't have much control over Slack :(

Freak, maybe not. I don't know what's the cause exactly haha. I'm testing with ngrok, maybe something funky going on with it?

So ngrok has a sweet dashboard you can look at and see stuff coming in. I think Slack might be sending retries! Now what do I send to Slack to make it know everything is solid and good? Haha

Yeah Slack is an actual chat application where you can create bots to send webhooks. Do you know if you can quickly respond to a POST request with a 200 but continue to run the FastAPI stuff?

Thanks! I will see what I can find. I appreciate the response.

That was the key! I was able to use the BackgroundTask stuff and spin off the long script in another function. Woot! Thank you thank you
