We’ve released an update to the Uptime Terraform Provider that adds support for our Secure Vault service. You can now securely assign Vault secrets to checks using service variables during check creation or updates—without exposing the actual secret values.

To do this, create a Vault item to store your secret, then link it to the check using a service variable (using the $VAR_NAME$ format).

This release also introduces a new credentials data source, allowing you to fetch a list of Vault secrets to help select the right one programmatically. 

Full documentation is available in the Terraform Registry for both service variables and the new credentials data source.
