Webhooks, explained without the jargon

The gap between knowing this and actually doing it is where most teams lose ground. Here is webhooks without the vocabulary that usually surrounds it.

Most development decisions are really maintenance decisions wearing a different hat. The practical test is whether someone new to the project could tell, in a minute, that it had been handled.

The short version

Webhooks replace polling with something closer to real time. Where this goes wrong is almost never a lack of knowledge. The version that survives contact with a real deadline is the simple one.

Why people complicate it

Most of the confusion comes from tooling rather than from the idea itself. There is a version of this that is over-engineered, and it is worth avoiding.

Always verify the signature before trusting a payload. In practice this is a scheduling problem more than a technical one. The version that survives contact with a real deadline is the simple one.

A reasonable first step

Assume delivery can repeat and design for it. Small and consistent beats large and occasional here. If two people in the business would answer this differently, that gap is the actual problem.

How to tell if yours is fine

Code gets read far more often than it gets written, and usually by someone with less context than the author had. Three things worth confirming about webhooks before you move on:

• Someone can say what the current setup is without going to look
• Webhooks replace polling with something closer to real time — and you know whether that is true here
• There is a way to tell whether the last change to this helped

If you want a second opinion on how yours is set up, ask.
