Disable notifications when updating a card.

Question

I made an app using the Mirror API and my idea was to allow the user to pin a card then send changes using the update option once a minute. It works great, but each update makes a noise which is very annoying.

Is there a way to disable the notification? I feel like with updates you should have the option.

Thanks!

Answer 1

If you are using timeline.update, then the new card you send should just leave out the notification field. You don't indicate what language you're using, but the representation would be something like

{
  "text": "hello world"
}

(You can set the notification field, as shown below, but it isn't necessary.)

If you're using timeline.patch, then you should make sure you explicitly set the notification field to NULL.

{
  "text": "hello world",
  "notification": null
}

Answer 2

When you're generating the /timeline/insert JSON, don't send a "notification" object and it will be sent to Glass without a noise.

Controls how notifications for this item are presented on the device. If this is missing, no notification will be generated.
