Sabre PassengerDetailsRQ API创建2成人PNR遇业务错误求助

Hey there, let's dig into why your PassengerDetailsRQ call works for 1 adult but throws a business error when adding a second. Based on your SOAP snippet and common Sabre API pitfalls, here are the most likely fixes to check:

1. Ensure Complete & Consistent Passenger Nodes #

Sabre is strict about multi-passenger data structure. Every adult passenger needs a fully populated <Passenger> node that meets these requirements:

• Valid name prefix (MR/MS/etc.)
• Full given name and surname
• Correct passenger type code (ADT)
• A unique ID that aligns with the IDs you used in your prior AirBookRQ request

Here's a working example of a 2-adult passengers block:

<Passengers>
  <Passenger Type="ADT" ID="1">
    <PersonName>
      <GivenName>JOHN</GivenName>
      <Surname>DOE</Surname>
      <NamePrefix>MR</NamePrefix>
    </PersonName>
  </Passenger>
  <Passenger Type="ADT" ID="2">
    <PersonName>
      <GivenName>JANE</GivenName>
      <Surname>DOE</Surname>
      <NamePrefix>MS</NamePrefix>
    </PersonName>
  </Passenger>
</Passengers>

2. Fix the EndTransactionRQ Configuration #

Your snippet cuts off the <EndTransactionRQ> section, but this is a common failure point for multi-passenger bookings. Make sure:

• You're not missing required sub-nodes like <Email> (if including contact info) or <AutoCancel>
• The HaltOnError="true" setting isn't masking detailed error messages. Try temporarily setting it to false to get a full error response—this will tell you exactly which field or node is causing the issue.

3. Match Passenger IDs Across AirBookRQ and PassengerDetailsRQ #

This is an easy mistake to make: the passenger IDs in PassengerDetailsRQ must exactly match the IDs you defined in the AirBookRQ's <TravelerInfo> section. If you only declared 1 traveler ID in AirBookRQ but tried to pass 2 in PassengerDetailsRQ, Sabre will throw a business error immediately.

4. Check for Misaligned Special Requests #

If you're adding ancillary services (meals, baggage, seats) for the two adults, double-check that each service request is linked to the correct passenger ID. A missing or mismatched ID here will break the booking for multiple passengers.

If none of these fix the issue, grab the full error response from Sabre—look for the <ErrorInfo> node, which will include a specific error code and human-readable description. Codes like INVALID_PASSENGER_DATA or MISSING_REQUIRED_FIELD will point you straight to the problem.
