Problems assigning tokens to users: "User has no push tokens registered."

I’m trying to utilise the Push service, and using the new push.saveToken(token) for the current 2.0 API.

In my inspector, I can see that the request is going out ok:

Request URL:
Request Method:POST
Status Code:201 CREATED

And it contains the correct data for that endpoint:


However, when I log in to, and view my apps Users, the user that matches the user_id given above states that “User has no push tokens registered.”

In order to send notifications to users instead of devices, I need these tokens assigned, but cannot for the life of me work out why the token isn’t persisted.

Any ideas anyone?
