# List domains in redirect_uri whitelist

`GET /projects/{project_id}/branches/{branch_id}/auth/domainsbeta`

Lists the trusted domains in the redirect URI whitelist for the specified branch. Only domains in this list are permitted as redirect targets after authentication.

```bash title="REST API - curl"
curl "https://console.neon.tech/api/v2/projects/$PROJECT_ID/branches/$BRANCH_ID/auth/domains" \
  -H "Authorization: Bearer $NEON_API_KEY"
```

Every field below is optional. An empty body works too.

Tool: `get_neon_auth_config`

Read full Neon Auth configuration for a branch. Do not use when you need to update config (use `configure_neon_auth` instead). Requires Neon Auth to be provisioned first (use `provision_neon_auth`). Returns Neon Auth (Better Auth) for a branch as one JSON object: integration metadata (base\_url, jwks\_url, db\_name, auth\_provider, branch\_id, created\_at, owned\_by, transfer\_status, auth\_provider\_project\_id), branch\_name from the Neon branch API, project\_id and resolved branch\_id, plus the same configurable fields as configure\_neon\_auth (trusted\_origins, allow\_localhost, auth\_methods.email\_password with enabled, allow\_sign\_up, verify\_email\_on\_sign\_up, verify\_email\_on\_sign\_in, email\_verification\_method, require\_email\_verification, auto\_sign\_in\_after\_verification, oauth\_providers (id, type, client\_id, client\_secret), email\_provider (discriminated by type)). Top-level base\_url, jwks\_url, and db\_name duplicate integration for quick copy. Optional \_errors records partial fetch failures for configurable slices. Secrets — OAuth client\_secret and the SMTP password — are NEVER returned. When the upstream config indicates a secret is set, this endpoint surfaces it as the literal sentinel "_**redacted**_"; when no secret is set the field is null. Use the matching configure\_neon\_auth operations to write or rotate these values.

- `projectId` (string, required)
  Neon project ID
- `branchId` (string, optional)
  Branch ID. If omitted, the project default branch is used (same as provision\_neon\_auth).

## Errors

default

General error

This endpoint can return the standard Neon API error response.

Response fields

- `message` Required. Human-readable error message.
- `code` Required. Machine-readable error code.
- `request_id` Optional. Request identifier for debugging. You can provide one with the `X-Request-ID` header.

Retry guidance

If no response is returned, the request may still have reached the server. This is why retry safety depends on the method and status code.

Idempotent methods (`GET`, `HEAD`, `OPTIONS`) are generally safe to retry after a network error or timeout. Non-idempotent methods (`POST`, `PATCH`, `DELETE`, `PUT`) can change state, so avoid automatic retries unless your workflow can tolerate duplicate effects.

Responses with `423 Locked` or `503 Service Unavailable` are safe to retry. `423 Locked` means the resource is temporarily locked, usually because another operation is in progress.
