POST method

[sergeyse]

When adding a card with a POST method or editing with PUT
TrelloClient.post('/cards?idList=xxxxxxxxxxxxxxxxxxxxx'').then(function (response) {.....}
returns invalid key 401 -
neither KEY no TOKEN are concatenated to request URL, in the Network tab in a browser it shows https://api.trello.com/1/cards?idList=xxxxxxxxxxxxxxxxxxxxxxxx

GET and DELETE are working fine
would you please let me know if this is my local problem , or it can be fixed and possible solution.
Thanks in advance.
