Send custom booking field values

​

Workflow

1. Call GET /apiv1/bookingdetails/{productPricesDetailsId} to retrieve the booking requirements for the selected fareprice.
2. Read the optional field IDs returned for that fareprice.
3. Send each answer in POST /apiv1/validateCart under redeemers[].products[].optionalFields[].

​

Required request shape

• optionalFieldId: the field ID returned by GET /apiv1/bookingdetails/{productPricesDetailsId}
• fieldText: the user-entered value for that field

{
  "redeemers": [
    {
      "firstName": "Alex",
      "lastName": "Lee",
      "products": [
        {
          "productPricesDetailsId": 12345,
          "redeemerQty": 1,
          "optionalFields": [
            {
              "optionalFieldId": 811109,
              "fieldText": "2:35"
            },
            {
              "optionalFieldId": 811110,
              "fieldText": "QF123"
            }
          ]
        }
      ]
    }
  ]
}

Notes

• Use the field IDs returned for the same fareprice and booking setup you are validating.
• Send one optionalFields entry per answer.
• If the fareprice does not return optional booking fields, you can omit optionalFields.
