> 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.

# Manage Managed Better Auth via the API

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

You can manage Managed Better Auth programmatically using the [Neon API](/guides/ai-agents-on-neon-reference-api), or from the terminal with the [Neon CLI](/guides/apis-sdks-cli-neon-auth) (`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](/guides/postgres-ai-neon-mcp-server#available-tools) (`provision_neon_auth`, `update_auth_config`, `add_auth_oauth_provider`, `get_neon_auth_config`). See [Set up with your AI editor](/guides/auth-index#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.

## Prerequisites

- A [Neon API key](/guides/manage-operate-manage-api-keys)
- 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](/guides/manage-operate-manage-projects#create-a-project-with-the-api) or [list branches](/guides/manage-operate-manage-branches#list-branches-with-the-api) via the API.

## Enable Managed Better Auth

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

```bash
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):

```json
{
  "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:

| Field                      | Description                                                                                               |
| -------------------------- | --------------------------------------------------------------------------------------------------------- |
| `auth_provider`            | The configured provider (`better_auth`)                                                                   |
| `auth_provider_project_id` | Unique ID for the auth provider instance                                                                  |
| `pub_client_key`           | Public client key (shown once at creation, may be empty for `better_auth`)                                |
| `secret_server_key`        | Secret server key (shown once at creation, may be empty for `better_auth`)                                |
| `jwks_url`                 | JWKS endpoint for JWT verification                                                                        |
| `schema_name`              | Database schema created for auth tables (`neon_auth`)                                                     |
| `table_name`               | Table name for synced user data (`users_sync`)                                                            |
| `base_url`                 | Base URL of the auth service, used for SDK configuration and the interactive API reference (`/reference`) |

**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](/guides/postgres-reference-javascript-sdk#initialize-the-client).

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"}`

## Get Auth configuration

Retrieve the current Managed Better Auth configuration for a branch:

```bash
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):

```json
{
  "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 configuration

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.

```bash
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):

```json
{
  "name": "My App"
}
```

| Field  | Description                                                    |
| ------ | -------------------------------------------------------------- |
| `name` | The name shown in user-facing auth messages (1-256 characters) |

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.

## Disable Managed Better Auth

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

```bash
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.
