Only some requests making it to callback url

[joeybab3]

I have a fulfillment service setup and a callback url waiting to receive requests and cancellation requests. I have it just logging the requests for now, but it seems to not really be sending requests for a lot of the events. 

So far I have previously received a few fulfillment requested and one cancellation requested. I know the endpoint works because I have received a few of these:

{"timestamp":"2024-09-11 15:51:58","storefront":"us","request":{"kind":"CANCELLATION_REQUEST"},"post_body":"{\"kind\":\"CANCELLATION_REQUEST\"}"}

But for whatever reason I can't get it to consistently send them. Any ideas?

HI， there

I guess there might be some reasons:

1. Verify that your endpoint is functioning correctly and ensure that your service is running smoothly.
2. If your endpoint is functioning properly, there might be an issue with the request-sending process. Review the logic of how requests are being sent.
3. Check if the URL callback is not changing.
4. Have you deactivated the fulfillment service location?

Did you ever get to the bottom of this? I'm consistently receiving FULFILLMENT_REQUEST webhook requests from Shopify, but have never received a CANCELLATION_REQUEST. Luckily I have a cron job that sweeps any assigned fulfillment cancellations up every 15 mins, so they're still processed after a delay.

I did not, it sort of started working for like ~45% of cancellation and fulfillment requests and I have a 10 minute cron to catch the rest as well.
