Errors

The API uses standard HTTP status codes and returns JSON error bodies.

HTTP Status Codes

Error Response Format

The API returns errors in the following format:

1
{
2
  "message": "Checkout Inválido",
3
  "errors": {
4
    "items": ["can't be blank"]
5
  }
6
}

The message field is always present. The errors object is optional and contains field-level validation details.

Common Errors

Error Handling

Always check the HTTP status code before processing the response:

1
if (response.status >= 400) {
2
  const error = await response.json();
3
  console.error('API Error:', error.message);
4
  
5
  // Handle specific validation errors
6
  if (error.errors) {
7
    Object.keys(error.errors).forEach(field => {
8
      console.error(`${field}: ${error.errors[field].join(', ')}`);
9
    });
10
  }
11
}
