Transaction and Trace IDs
The JSON Air APIs support transaction and trace IDs for both GDS Global Distribution System. A GDS aggregates and distributes air, hotel, and car rental content such as schedules, fares, and upsells. In the JSON APIs, GDS content is distributed from Travelport. and NDC
New Distribution Capability, an XML standard for exchanging data that supports airlines in distributing their content directly to online travel agencies. See the NDC Guide. content. These IDs can be used to assist in tracking and troubleshooting if you need Support Options.
Tracking IDs in the Request
The JSON APIs support two separate tracking IDs, one issued by Travelport by default (transactionId) and another that customers can send by choice (traceId). TraceId is sent in the message request header, and both transactionId and traceId are returned in the response header and/or response payload depending on transaction type.
-
transactionId is always returned and is unique to a single transaction.
-
traceId is returned only if sent by the customer. Can be sent in all transaction types to add the same common identifier to all transactions in a workflow.
Do not confuse traceId with the Open Telemetry TraceId header.
For more about headers, see Common Air Headers.

Tracking IDs in the Response
All JSON API responses return the system-generated transaction ID A tracking id returned in the transactionId object under the first top-level object of every response in the JSON APIs. This system-generated ID assists Travelport and customers with troubleshooting if needed. In addition, developers can send a custom traceId in the header as their own tracking number. See Transaction and Trace IDs on the General menu.. Most responses return the ID in the transactionId object in the first object of the response payload (object name varies by API) and in the e2etrackingid field in the response header, although some APIs return it only in the header.
If you send a trace ID in the header, the response returns that ID. Most responses return a traceId object with your traceID value in the first object in the response payload and in the TraceID field in the response header, although some APIs return it only in the header. If you do not send a trace ID, traceId is not returned.
The following example shows the transaction and trace IDs as returned in the headers and response payloads of different APIs.
