Webhooks and APIs: how your tools actually talk to each other
A non-technical explanation of the plumbing behind automation — webhooks, APIs and integration platforms — and why it matters for your project.
Every automation is really just moving information between systems at the right moment. Two mechanisms do almost all of that work: webhooks and APIs.
Webhooks: "tell me when something happens"
A webhook is a system pushing a message the instant an event occurs — a form is submitted, a payment clears, a deal changes stage. Your automation listens for that message and reacts. It's real-time and efficient because nothing is constantly checking.
APIs: "let me ask or do something"
An API lets one system request data from another ("what's this customer's order history?") or make a change ("create this appointment"). Automations use APIs to look things up and take action.
Integration platforms
- Tools that sit in the middle, catching webhooks and calling APIs without custom code.
- Good for standard connections and quick wins.
- Custom code still wins when logic is complex, volume is high, or you need tight control.
Why you should care
When scoping a project, the key question is whether the tools you use expose the webhooks and API endpoints you need. If they don't, that constrains what's possible — better to know on day one.
