envs add customerio/apiThis declares the keys below in your catalog and sets none of them. A template is a schema for keys; it never carries a value.
| Key | Needed | Kind | Notes |
|---|---|---|---|
CUSTOMERIO_SITE_ID |
required | secret | Half of the basic auth pair the Track API takes. Despite the name this is not a public site identifier.. where to get it |
CUSTOMERIO_API_KEY |
required | secret | The other half of that pair.. where to get it |
CUSTOMERIO_APP_API_TOKEN |
optional | secret | For the App API, which is bearer rather than basic and carries its own scopes.. where to get it |
CUSTOMERIO_WRITE_KEY |
optional | secret | The CDP key. Customer.io's browser and server SDKs take the same value, and it says nothing about publishing it, so it stays secret: putting it in a bundle exposes the credential the server uses too.. where to get it |
