Create a Pledge Gift

I am trying to create pledge gifts, for which I use the following service https://developer.sky.blackbaud.com/docs/services/gft-gifts/operations/CreateGift.
However I am getting the following error message:

[{"message":"The requiered argument 'addGift' was not asigned a value","error_name":"RequiredArgumentNoAssigmentValue","error_code":2,"raw_message":"The required argument '{
0}' was not assigned a value","error_args":["addGift"]}]

Send the following data structure:

"value": 1

• Do I need to add more information to my data structure?
• Is there misconfigured data?
