</AccordionGroup>

## Examples

<Tabs>
  <Tab title="Basic GTM">
    Add the client GTM container ID and enable the standard checkout events they need.
  </Tab>

  <Tab title="Custom trigger">
    Add a custom event name when the client GTM workspace listens for a custom page-load trigger.

  <Tab title="Cleanup">

</Tabs>

## Before saving

* Validate container IDs with the client GTM workspace.
* Keep custom event names simple and consistent with the client trigger names.
* Avoid duplicate GTM IDs across GTM Events and Pixels.
