# CustomerErrorCode

Possible error codes that can be returned by customer mutations. These errors help developers understand what went wrong during customer authentication, registration, or account operations.

## Enum Definition

```graphql
enum CustomerErrorCode {
  INVALID_CREDENTIALS
  UNIDENTIFIED_CUSTOMER
  TOKEN_EXPIRED
  TOKEN_INVALID
  TOO_MANY_ATTEMPTS
  EMAIL_TAKEN
  INVALID_EMAIL
  INVALID_PASSWORD
  PASSWORD_MISMATCH
  LOGIN_DISABLED
  REGISTRATION_DISABLED
  BLANK
}
```

## Values

| Value | Description |
|-------|-------------|
| INVALID_CREDENTIALS | The email or password is incorrect |
| UNIDENTIFIED_CUSTOMER | The customer could not be identified |
| TOKEN_EXPIRED | The access token has expired |
| TOKEN_INVALID | The access token is invalid |
| TOO_MANY_ATTEMPTS | Too many login attempts. Please try again later. |
| EMAIL_TAKEN | The email address is already registered |
| INVALID_EMAIL | The email address is invalid |
| INVALID_PASSWORD | The password does not meet requirements |
| PASSWORD_MISMATCH | The password and password confirmation do not match |
| LOGIN_DISABLED | Customer login is disabled for this store |
| REGISTRATION_DISABLED | Customer registration is disabled for this store |
| BLANK | A required field is blank |

## Example

```graphql
mutation LoginCustomer {
  customerLogin(email: "user@example.com", password: "password123") {
    customer {
      id
      email
    }
    errors {
      code
      message
    }
  }
}
```

In this example, if the login fails, the `errors` field may contain a `code` value of type `CustomerErrorCode`, such as `INVALID_CREDENTIALS` or `TOO_MANY_ATTEMPTS`.
