This guide helps you bring secrets from Doppler into Infisical. Register a Doppler App Connection once, link it under External Migrations, then import secrets on demand — from the organization settings or directly from a project’s secret overview — into any Infisical project, environment, and folder you choose.
What you can migrate:
Store the token securely; you will paste it into Infisical in the next step.
Provide the token and complete the connection flow. The connection is reused anywhere Infisical needs to talk to Doppler for migration.
Under **In-Platform Migration Tooling**, click **Add configuration**. In the provider chooser, select **Doppler**.

Pick the **App Connection** you created (each row in the table is one linked connection).

<Note>
If you need several Doppler sources (for example different credentials), add multiple **Doppler** rows from **Add configuration**; each row can use a different App Connection.

The **In-Platform Migration Tooling** table lists all configured platforms (Vault and Doppler) together: **Platform**, **Namespace** (Vault shows the namespace path; Doppler shows **—**), and **Connection**.
When you are already in a Secret Manager project and have one environment selected (not “all environments”):
