Amadeus flights API error: carrier code is a 2 or 3 alphanum except YY and YYY - json

Question

I am using the following SDK to search for and purchase flights via Amadeus:
https://github.com/autotune/amadeus/pull/1/files
This was a previously abandoned project I have decided to take on and make work. As part of that project I am trying to purchase a ticket in the sandbox environment and getting the following error:
{
"errors": [
{
"code": 477,
"title": "INVALID FORMAT",
"detail": "carrier code is a 2 or 3 alphanum except YY and YYY",
"source": {
"pointer": "/data/flightOffers[0]/itineraries[1]/segments[0]/operating/carrierCode",
"example": "AF"
},
"status": 400
}
]
}
Here is the json data being sent:
{
"type": "flight-order",
"travelers": [
{
"id": "1",
"dateOfBirth": "1990-02-15",
"name": {
"firstName": "Foo",
"lastName": "Bar"
},
"gender": "MALE",
"contact": {
"emailAddress": "foo#bar.com",
"phones": [
{
"deviceType": "MOBILE",
"countryCallingCode": "33",
"number": "5555555555"
}
]
}
}
],
"ticketingAgreement": {
"option": "DELAY_TO_CANCEL",
"delay": "6D"
},
"remarks": {},
"operating": {
"carrierCode": "UA"
}
}
Any help appreciated!

Answer 1

The error suggests that the sent payload is invalid. I'd advice you use a tool like Curl or Postman to verify you're using the right API documentation, before debugging actual code.

Answer 2

After further reading your PR and checking the API reference at :
https://developers.amadeus.com/self-service/category/air/api-doc/flight-create-orders/api-reference
I think you need to confirm that the Carrier code being passed is available in the segments under:
flightOffers > itineraries > segments
Although the API reference doesn't have operating > carrierCode like you used in the data sent, my guess after seeing the API error response you shared is that they are performing a check against the flight offers passed.
I suggest you check the results gotten when you call the flightOffers and also add it to the payload sent to the sandbox.
