If you want to change an existing booking the parameter fltnr needs to be provided. It is not possible to change the date, courseloops or teetime of an existing booking. IN that case you need to cancel the booking first and make a new booking immediately afterwards. Parameters you can change to an existing booking are:
|players	|the nr of players (min 1 max 4)|
|relnr1	|the id of the 1st golfer in the flight (the owner of the booking) (mandatory)|
|relnr2	|the id of the 2nd golfer in the flight if players>1. |
|relnr3	|the id of the 3rd golfer in the flight if players>2. |
|relnr4	|the id of the 4th golfer in the flight if players>3. |
|name2	|name of the 2nd golfer if players>1 and relnr2=0|
|name3	|name of the 3rd golfer if players>2 and relnr3=0|
|name4	|name of the 4th golfer if players>3 and relnr4=0|
|cirnr2	|id of invitation option for player 2 (relnr2 and name2 are ignored)|
|cirnr3	|id of invitation option for player 3 (relnr3 and name3 are ignored)|
|cirnr4	|id of invitation option for player 4 (relnr4 and name4 are ignored)|
|buggy	|if 1 a buggy or handicap will be booked|

the parameter relnr is used to register who made the booking or who made the cange to an existing booking. Often it will be equal to relnr1, but it doesn’t have to be. However, it is good practise not to allow anyone else change a booking, so relnr will probably always be equal to relnr1, relnr2, relnr3 or relnr4.

example: https://backend.ikgagolfen.nl/igg/bookteetime?auth=<your authorisation code>crsnr=1&date=20121001&teetime=600&crlnr1=6&crlnr2=22&players=2&relnr1=701160&name2=Henk&testonly=1

result (if succesful):
<code>{
  "bookteetime": [
    {
      "fltnr": 3058329,
      "errormsg": "",
      "helpurl": ""
    }
  ]
}</code>


or if the bookings fails:
<code>{
  "bookteetime": [
    {
      "fltnr": 0,
      "errormsg": "probleem met beschikbaarheid 10:00, rood (2 spelers)",
      "helpurl": ""
    }
  ]
}
</code>
if a wrong authorisation code is provided, the backend will return “no authorisation”
