# About the Custom Trigger API

The Custom Trigger API allows you to run automations on a Wix site from your code.

Automations created as part of an app or on a site have a set [trigger](https://dev.wix.com/docs/rest/business-management/automations/triggers/about-triggers.md) that causes them to run. The trigger is typically a business event like a member login or invoice payment. An automation only runs for that specific event.

Using the Custom Trigger API, you can run an automation without tying it to a single specific event or creating a trigger in the app dashboard. This gives you greater control and flexibility over when your automations execute.

The API includes a single method, [Run Trigger](https://dev.wix.com/docs/rest/business-management/automations/triggers/custom-trigger/run-trigger.md), that you can call anywhere in your code.

## Before you begin

- You must have the [trigger ID](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/automations/about-custom-triggers.md#the-trigger-id) of any automations you want to run.
- If the custom trigger includes a [payload schema](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/automations/about-custom-triggers.md#the-payload-schema), you need to know the fields it contains.

## Use cases

- Create a contact on a button click.
- Update a Google sheet when a user inputs a value.
