Nuki Web API: problem when creating an authentication code for the Keypad

Hello, We made a request from the web API for asking the creation of a new keypad code:


“name”: « TEST »

“smartlockIds”: [



“remoteAllowed”: false,

“smartActionsEnabled”: true,

“type”: 13,

“code”: 565656


Returns 204,

So ok.

But we have the error pop up (see screenshot) and in the end no code is created.

This problem only happens on a single Smart Lock / Keypad

Have you ever experienced this problem?

Some help would be greatly appreciated!
