Setting environment variables - AWS Amplify Hosting
Create a new backend environment with authentication parameters for social sign-in

Setting environment variables

Use the following instructions to set environment variables for an application in the Amplify console.

Note

Environment variables is visible in the Amplify console’s App settings menu only when an app is set up for continuous deployment and connected to a git repository. For instructions on this type of deployment, see Getting started with existing code.

To set environment variables

  1. Sign in to the AWS Management Console and open the Amplify console.

  2. In the Amplify console, choose Hosting, and then choose Environment variables.

  3. On the Environment variables page, choose Manage variables.

  4. For Variable, enter your key. For Value, enter your value. By default, Amplify applies the environment variables across all branches, so you don’t have to re-enter variables when you connect a new branch.

  5. (Optional) To customize an environment variable specifically for a branch, add a branch override as follows:

    1. Choose Actions and then choose Add variable override.

    2. You now have a set of environment variables specific to your branch.

  6. Choose Save.
