使用Amadeus航班搜索API Explorer时持续返回400 Bad Request错误的技术咨询

I’ve run into similar hiccups testing Amadeus APIs before, so let’s walk through the most likely fixes for the 400 errors you’re hitting:

• Refresh your authentication token: Test environment tokens expire after 30 minutes, and even the API Explorer can hold onto expired ones. Head to the "Authorize" button in the Explorer, re-authenticate, and try your requests again—this is the #1 fix for random 400s.
• Double-check date validity: Make sure your departureDate follows the strict YYYY-MM-DD format (yours look correct) and that it’s not a past date. Amadeus rejects any search for flights that have already departed.
• Validate airport codes: Confirm your originLocationCode and destinationLocationCode are valid 3-letter IATA codes. Your examples (SYD/BKK, TLV/DBX) are correct, but typos here are super easy to miss.
• Audit parameter values:
  • nonStop needs to be a lowercase boolean (true/false)—no uppercase letters or extra spaces allowed.
  • The max parameter’s upper limit is 250 for this API, which you’re using correctly, but if you ever tweak that number, don’t go over the limit.
• Dig into the error response details: The 400 error will include a detail field in the JSON response that spells out exactly what’s broken. For example, it might say "Invalid departure date" or "Missing required parameter". Check this first—it’s the fastest way to pinpoint the issue.
• Test a minimal request: Start with only the required parameters: originLocationCode, destinationLocationCode, departureDate, adults. If that works, add back nonStop and max one at a time to isolate the problem.
• Avoid pre-encoded URLs: Your first link uses & instead of &—while the Explorer should handle this, try building the request directly in the Explorer’s parameter form instead of pasting the URL to rule out encoding issues.
