Error Response Formats

Each Envia API has its own error response shape. This page documents the real formats returned by the Shipping, Queries, and Geocodes APIs so you can handle them correctly in your integration.

Error response formats

Each Envia API returns errors in its own format. Your error-handling code should account for these differences.

Shipping API

The Shipping API wraps errors inside a meta / error object:

{
  "meta": "error",
  "error": {
    "code": 400,
    "description": "Invalid Option",
    "message": "The origin.postalCode field is required."
  }
}

⚠️

Important: Some Shipping API errors return HTTP 200 with "meta": "error" in the body instead of a 4xx status code. Always check the meta field in the response — do not rely solely on the HTTP status code.

Authentication errors on the Shipping API return a plain-text string instead of JSON:

"Authentication error."

Handle this case in your code by checking the Content-Type header or wrapping JSON parsing in a try/catch.

Queries API

The Queries API uses a different structure:

{
  "statusCode": 401,
  "error": "Unauthorized",
  "message": "Invalid or expired token."
}

Geocodes API

The Geocodes API follows the same structure as the Queries API:

{
  "statusCode": 404,
  "error": "Not Found",
  "message": "Postal code not found for the given country."
}

Handling all three formats

Since each API has its own error shape, a robust integration should normalize errors into a common internal format. Here is a simple approach:

function parseEnviaError(response, body) {
  // Shipping API — plain-text auth error
  if (typeof body === "string") {
    return { code: response.status, message: body };
  }
  // Shipping API — meta/error wrapper
  if (body.meta === "error") {
    return { code: body.error?.code, message: body.error?.message };
  }
  // Queries & Geocodes API
  if (body.statusCode) {
    return { code: body.statusCode, message: body.message };
  }
  return { code: response.status, message: "Unknown error" };
}

💡

Tip: Some carrier-level errors include an additional carrier_message field with the carrier's own error text — useful when debugging carrier-specific rejections.

Getting help

If an error persists after checking the response format:

1. Capture the full JSON error response including carrier_message if present
2. Note the endpoint URL, HTTP method, and timestamp
3. Open a support ticket with these details
