使用Shippo API创建新地址时出现500错误，请求排查问题

Hey there, let's figure out why you're hitting that 500 error with the Shippo API. Server-side 500 errors can feel vague, but they often trace back to small issues in your code or setup. Let's break down the fixes step by step:

1. Fix the Critical Syntax Error #

First off, I spotted a big issue in your code: you're using => instead of PHP's valid array arrow syntax =>. Those are HTML entities (used for displaying arrows in web content), not proper PHP syntax. This is almost certainly causing a fatal PHP error that's leading to the 500 response.

Here's your code with the corrected arrow syntax:

require_once ABSPATH . '/shippo/shippo/lib/Shippo';
Shippo::setApiKey("test_token"); // Ensure this is your full valid test token (starts with shippo_test_)

$address = Shippo_Address::create(
    array(
        'object_purpose' => 'QUOTE',
        'name' => 'John Smith',
        'company' => 'Initech',
        'street1' => '6512 Greene Rd.',
        'city' => 'Woodridge',
        'state' => 'IL',
        'zip' => '60517',
        'country' => 'US',
        'phone' => '773 353 2345',
        'email' => 'jmercouris@iit.com',
        'metadata' => 'Customer ID 23424'
    )
);

var_dump($address);

2. Verify Your Test API Token #

Double-check that your test token is complete and correctly formatted. Shippo's test tokens always start with shippo_test_—if yours is missing that prefix or has typos, it could trigger unexpected server errors.

3. Enable PHP Error Reporting #

To see exactly what's going wrong (instead of just a generic 500), add these lines at the very top of your script:

error_reporting(E_ALL);
ini_set('display_errors', 1);

This will reveal any PHP fatal errors, warnings, or notices that might be hidden otherwise.

4. Simplify Your Request #

If fixing the syntax doesn't resolve the issue, try stripping down the address to only required fields to rule out parameter-related problems. For example:

$address = Shippo_Address::create(
    array(
        'object_purpose' => 'QUOTE',
        'name' => 'John Smith',
        'street1' => '6512 Greene Rd.',
        'city' => 'Woodridge',
        'state' => 'IL',
        'zip' => '60517',
        'country' => 'US'
    )
);

If this works, add back optional fields one by one to pinpoint which one might be causing the issue.

5. Check Shippo Library Version #

Outdated versions of the Shippo PHP library might have compatibility issues with the latest API endpoints. Make sure you're using the most recent version—you can update it via Composer or by downloading the latest files from Shippo's official repo.
