integrations
A webhook is an automatic notification a phone system sends to another app the instant something happens, like a call ending or a text arriving. This lets that other app react immediately without checking back for updates.
Instead of an app repeatedly asking "has anything new happened yet", a webhook works the opposite way. The phone system pushes a message to a specified web address the moment an event occurs, containing details about what happened.
For a small business, webhooks are usually invisible plumbing behind integrations. Examples include triggering a Slack notification when a call is missed, or kicking off a Zapier workflow that creates a task when a new text arrives.
Setting one up typically requires a destination URL from the receiving app (a CRM, Slack, or automation tool like Zapier), pasted into the phone system's settings. No coding is required.
Worked example
A 4-person business connects a webhook so every missed call posts a message into a shared Slack channel instantly.
The team sees and responds to missed calls within minutes, instead of discovering them hours later in the call log.
Why it matters to a small team
For a small team without a developer, webhooks (often set up through a no-code tool like Zapier) let call and text events trigger useful actions elsewhere automatically. This closes gaps that would otherwise need someone to notice and act manually.
Not usually for common setups; many phone systems connect to no-code tools like Zapier or Slack where a webhook is configured through a simple settings screen rather than custom code.
Common triggers include a missed call, a new voicemail, an incoming text, or a call ending, each of which can notify another app or start an automated workflow.
Not exactly; an API is a broader set of ways two systems can talk to each other, while a webhook is a specific, one-directional notification pattern often built using an API underneath it.
