Prerequisites:

  1. Navigate to Project > Integrations and select the Secret Syncs tab. Click on the Add Sync button.

  2. Select the Heroku option.

  3. Configure the Source from where secrets should be retrieved, then click Next.

    • Environment: The project environment to retrieve secrets from.
    • Secret Path: The folder path to retrieve secrets from.

If you need to sync secrets from multiple folder locations, check out secret imports.

  1. Configure the Destination to where secrets should be deployed, then click Next.

    • Heroku App Connection: The Heroku App Connection to authenticate with.
    • Heroku App: The Heroku application to sync secrets to.
  2. Configure the Sync Options to specify how secrets should be synced, then click Next.

    • Initial Sync Behavior: Determines how Infisical should resolve the initial sync.
      • Import - Prefer values from Infisical: Import secrets from Heroku to Infisical; if a secret with the same name already exists in Infisical, do nothing. Afterwards, sync secrets to Heroku.
      • Import - Prefer values from Heroku: Import secrets from Heroku to Infisical; if a secret with the same name already exists in Infisical, replace its value with the one from Heroku. Afterwards, sync secrets to Heroku.
      • Overwrite Destination Secrets: Removes any secrets at the destination endpoint not present in Infisical.
    • Key Schema: Template that determines how secret names are transformed when syncing, using {{secretKey}} as a placeholder for the original secret name and {{environment}} for the environment.

    We highly recommend using a Key Schema to ensure that Infisical only manages the specific keys you intend, keeping everything else untouched.

    • Auto-Sync Enabled: If enabled, secrets will automatically be synced from the source location when changes occur. Disable to enforce manual syncing only.
    • Disable Secret Deletion: If enabled, Infisical will not remove secrets from the sync destination. Enable this option if you intend to manage some secrets manually outside of Infisical.
  3. Configure the Details of your Heroku Sync, then click Next.

    • Name: The name of your sync. Must be slug-friendly.
    • Description: An optional description for your sync.
  4. Review your Heroku Sync configuration, then click Create Sync.

  5. If enabled, your Heroku Sync will begin syncing your secrets to the destination endpoint.
