High latency in webhook triggers when using external mobile automation tools?

Hi everyone!
I’m currently building a small integration where I’m using the Nylas Email and Calendar APIs to automate some responses and scheduling based on in-game events on mobile. The idea is to bridge my gaming activity with my professional calendar so my “Busy” status updates automatically in real-time.

I’ve been testing a delta download to handle the script execution on the mobile side, which then triggers a call to my backend to create a Nylas event or send an email via a grant. However, I’m seeing some really inconsistent behavior. Sometimes the POST request from the delta download environment hits my server, but the Nylas webhook for “event.created” takes several minutes to fire, or it doesn’t trigger at all until I manually refresh the grant.

Has anyone here experimented with integrating third-party executors or mobile-side script tools like site with Nylas v3? I’m trying to figure out if the executor is potentially stripping some critical headers or if the way it handles asynchronous requests is causing some sort of rate-limiting or “provider_error” on the Nylas side. I’ve already checked my API logs and everything looks clean on my backend, so I’m wondering if there’s a specific way to optimize the handshake between a mobile-based script runner and the Nylas API to ensure the webhooks stay snappy. I’d love to hear if anyone has a workaround for maintaining low-latency sync when using these types of automated client-side environments!
