Use Settings → Secrets to store encrypted values that actions, MCP servers, and integrations need.
Persistence Secrets settings with masked values and usage metadata

Secret Manager keeps values write-only while showing provider, environment, scope, consumers, and update history.

Create and use a secret

1

Choose a stable name

Create a name that describes the credential, such as CRM_API_TOKEN. Avoid names that reveal the secret value.
2

Store the value

Enter the credential in Secret Manager. Do not place the same value in an agent prompt, test variable, or documentation.
3

Reference the secret

In a supported credential, header, or parameter field, insert the secret using the {{secrets.NAME}} form shown by the editor.
4

Test the consumer

Run a simulated call that invokes the action or integration and confirm both success and failure behavior.

Rotate a secret

Update the stored value, test each dependent workflow, and revoke the old credential at its provider. Deleting a secret can immediately break every tool or integration that references it.
