Automate branching with GitHub Actions

Create and delete branches with GitHub Actions

Neon provides the following GitHub Actions for working with Neon branches, which you can add to your CI workflows:

tip

Neon supports a GitHub integration that connects your Neon project to a GitHub repository. The integration automatically configures a NEON_API_KEY secret and PROJECT_ID variable in your GitHub repository and provides a sample GitHub Actions workflow that utilizes Neon's Create branch and Delete branch actions. See Neon GitHub integration for more.

Create branch action

This GitHub Action creates a new branch in your Neon project.

info

The source code for this action is available on GitHub.

Prerequisites

  • Using the action requires a Neon API key. For information about obtaining an API key, see Create an API key.
  • Add your Neon API key to your GitHub Secrets:
    1. In your GitHub repository, go to Project settings and locate Secrets at the bottom of the left sidebar.
    2. Click Actions > New Repository Secret.
    3. Name the secret NEON_API_KEY and paste your API key in the Secret field
    4. Click Add Secret.

Example

The following example creates a branch based on the specified parent branch:
