Bargain Finder Max API请求报错：No Pax types given 求解决方案

Hey there! That error is straightforward—your API request is missing required passenger (Pax) type details, which the Bargain Finder Max API needs to process your search. Here's how to fix it step by step:

1. Add the Pax Type Section to Your Request Dictionary #

The API requires explicit details about the number of passengers by type (adults, children, infants, etc.). You’ll need to include this as a key-value pair in your request dictionary. For example:

request_dict = {
    # Your existing fields (origin, destination, dates, etc.)
    "Origin": "SFO",
    "Destination": "ORD",
    "DepartureDate": "2024-11-15",
    # Add the required Pax section
    "Pax": {
        "AdultCount": 1,  # Required minimum is usually 1
        "ChildCount": 0,
        "InfantCount": 0
    }
}

Double-check the exact field names against the API documentation—some variants might use Passengers instead of Pax, but the error message confirms it’s looking for Pax-related data.

2. Verify Nested Structure and Spelling #

Make sure the Pax section is correctly nested in your main request dictionary. Common mistakes include:

• Typing errors (e.g., lowercase pax instead of uppercase Pax)
• Forgetting to nest the count fields under the Pax key (e.g., putting AdultCount directly in the root dictionary)

3. Confirm JSON Conversion Preserves the Structure #

When using json.dumps() to convert your dictionary to JSON, ensure the Pax section isn’t accidentally excluded. You can debug by printing the converted JSON to check:

import json

json_payload = json.dumps(request_dict)
print(json_payload)  # Check if the "Pax" key and its values are present

If the Pax section shows up here but you still get the error, double-check that your request headers include Content-Type: application/json to ensure the API parses the payload correctly.

Example Full Request #

Here’s a complete snippet to reference:

import json
import requests

# Build the full request payload with Pax details
payload = {
    "Origin": "JFK",
    "Destination": "MIA",
    "DepartureDate": "2024-10-20",
    "ReturnDate": "2024-10-27",
    "Pax": {
        "AdultCount": 2,
        "ChildCount": 1
    },
    # Include other required API parameters (e.g., carrier preferences, cabin class)
}

# Convert to JSON and send request
headers = {"Content-Type": "application/json", "Authorization": "Your_API_Key"}
response = requests.post(
    "https://api.bargainfindermax.example.com/search",
    data=json.dumps(payload),
    headers=headers
)

# Check response
print(response.json())
