Webhook guides
The problems that show up once webhooks are in production, each with the reasoning and the code.
Your first delivery
Account, destination, publish, and the timeline that proves it arrived.
Verifying webhook signatures
The three headers, a verification function, and the mistake everyone makes once.
Retries and idempotency
What a retry preserves, and how a consumer stops processing the same event twice.
Dead letters and recovery
What happens when the schedule is spent, and how to get the events back.
Testing webhooks
How to exercise a consumer without waiting for real traffic.
Debugging a failing delivery
Reading the timeline: what each status code usually means and what to do about it.
Webhooks and SSRF
Why a delivery service is an SSRF machine by construction, and how to contain it.
