Why webhooks matters more than it looks

Teams tend to reach for this after something has already gone wrong. Webhooks is easy to treat as a detail, and that is exactly why it is worth a few minutes of attention.

Code gets read far more often than it gets written, and usually by someone with less context than the author had. It is the sort of thing that looks like polish right up until it costs you an enquiry.

Why this earns attention

Webhooks replace polling with something closer to real time. This is the sort of thing that compounds, quietly, in both directions. The practical test is whether someone new to the project could tell, in a minute, that it had been handled.

Always verify the signature before trusting a payload. None of that requires a large budget, only a decision and someone to own it. Doing this properly once is usually cheaper than doing it approximately three times.

What to watch for

Assume delivery can repeat and design for it. The teams that handle this well are rarely the ones with the biggest budgets. Assume whoever inherits this will have half your context and none of your patience.

In practice

Most development decisions are really maintenance decisions wearing a different hat. Three things worth confirming about webhooks before you move on:

• Someone can say what the current setup is without going to look
• Assume delivery can repeat and design for it — and you know whether that is true here
• There is a way to tell whether the last change to this helped

Worth checking on your own setup before it becomes someone else's problem to fix.
