Summary: Managed Better Auth REST API operations for enabling (POST), retrieving (GET), updating (PATCH), and disabling (DELETE) auth on a per-branch basis, with curl examples and a full response field reference. Use this page when automating auth provisioning or teardown: the enable response is the only call that returns pub_client_key and secret_server_key, and the delete_data flag on DELETE controls whether the neon_auth schema is permanently removed. Also covers related branch-scoped endpoints for OAuth providers, email configuration, domains, users, plugins, and webhooks, plus equivalent MCP tools for AI-editor workflows.

Enable, configure, and disable Managed Better Auth using the Neon API

You can manage Managed Better Auth programmatically using the Neon API, or from the terminal with the Neon CLI (neon neon-auth), which wraps these same operations. You can also enable and configure Managed Better Auth from an AI editor using the Neon MCP server (provision_neon_auth, update_auth_config, add_auth_oauth_provider, get_neon_auth_config). See Set up with your AI editor.

Note: Managed Better Auth operates at the branch level. Each branch can have its own independent auth configuration, which means preview and development branches can have separate auth state from your production branch.

• A Neon API key
• A Neon project with at least one branch

All requests use the base URL https://console.neon.tech/api/v2 and require the Authorization: Bearer $NEON_API_KEY header. The project_id and branch_id values are returned when you create a project or list branches via the API.

Send a POST request to enable Managed Better Auth on a branch:

curl -X POST 'https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth' \
  -H 'Authorization: Bearer $NEON_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"auth_provider": "better_auth"}'

Response (201 Created):

{
  "auth_provider": "better_auth",
  "auth_provider_project_id": "cab6949a-10e3-4d25-a879-512beed281e3",
  "pub_client_key": "",
  "secret_server_key": "",
  "jwks_url": "https://ep-example.neonauth.us-east-1.aws.neon.tech/neondb/auth/.well-known/jwks.json",
  "schema_name": "neon_auth",
  "table_name": "users_sync",
  "base_url": "https://ep-example.neonauth.us-east-1.aws.neon.tech/neondb/auth"
}

The response includes:

Important: The enable response is the only time the API returns pub_client_key and secret_server_key. Store them securely. Subsequent GET requests do not include these fields. For client initialization examples that combine Neon Auth and the Data API from a single Neon URL, see createClient() in the JavaScript SDK reference.

If Managed Better Auth is already enabled on the branch, this call returns an error.

Tip: Using a non-default database

By default, Managed Better Auth uses the branch's default database. To target a different database, add database_name to the request body: {"auth_provider": "better_auth", "database_name": "my_other_db"}

Retrieve the current Managed Better Auth configuration for a branch:

curl -X GET 'https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth' \
  -H 'Authorization: Bearer $NEON_API_KEY'

Response (200 OK):

{
  "auth_provider": "better_auth",
  "auth_provider_project_id": "cab6949a-10e3-4d25-a879-512beed281e3",
  "branch_id": "br-example-abc123",
  "db_name": "neondb",
  "created_at": "2026-02-26T04:29:05Z",
  "owned_by": "neon",
  "jwks_url": "https://ep-example.neonauth.us-east-1.aws.neon.tech/neondb/auth/.well-known/jwks.json",
  "base_url": "https://ep-example.neonauth.us-east-1.aws.neon.tech/neondb/auth",
  "name": "My App"
}

Update auth settings for a branch. Currently supports changing the application name shown in user-facing auth messages. Applies to Managed Better Auth integrations only. Defaults to the Neon project name.

curl -X PATCH 'https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth/config' \
  -H 'Authorization: Bearer $NEON_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"name": "My App"}'

Response (200 OK):

{
  "name": "My App"
}

Each branch manages its own application name independently. You can also update this from the Auth page > Configuration tab > Project Info panel in the Neon Console.

Send a DELETE request to disable Managed Better Auth on a branch:

curl -X DELETE 'https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth' \
  -H 'Authorization: Bearer $NEON_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"delete_data": true}'

Response (200 OK): Empty body.

The delete_data field controls whether the system removes the neon_auth schema from your database:

• true: Deletes the neon_auth schema and all auth tables (users, sessions, accounts).
• false (default): Disables the auth service but leaves the schema and data intact. You can re-enable later without losing user data.

Warning: Setting delete_data to true permanently removes all auth data from the database. You cannot undo this.

The Neon API also provides endpoints for managing auth configuration at the branch level. These are available at https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id}/auth/...:

For full request/response details on these endpoints, see the interactive API Reference.

Tip: TypeScript SDK

You can also manage Managed Better Auth using the Neon TypeScript SDK.
