A little slow to respond here, so maybe this is no longer applicable... I just ran a test and no issues on my end with webhooks. I have a post call analysis webhook that sends caller details over to Airtable. It's working for me...

Good to know it's working on your end. It makes me wonder if the issue is tied to a specific webhook configuration or environment rather than Retell itself.
Have you noticed any delays or failed deliveries under heavier call volumes? @Jason

Yeah, maybe that's the case.
I haven't done any high volume performance testing. It's a good thought though, i should look at doing that. My agent serves as a lead capture for my own agency and I'm pretty new, so the volumes are not there yet. @Podziemski

That’s actually a good time to test before traffic picks up. I'd start with small batch load tests, monitor webhook response times and retries, then verify every payload reaches Airtable without duplicates or missed records. That way you'll know exactly where the bottleneck is before you start getting real lead volume.

Yeah...Great tip @Podziemski , Thanks. I'm going to work on that this week. I had another little issue I was working on, but will get on that soon.
