The Pebble timeline is a system-level display of chronological events that apps can insert data into to deliver user-specific data, events, notifications and reminders. These items are called pins and are accessible outside the running app, but are deeply associated with an app the user has installed on their watch.
Every user can view their personal list of pins from the main watchface by pressing Up for the past and Down for the future. Examples of events the user may see include weather information, calendar events, sports scores, news items, and notifications from any web-based external service.

To push pins via the Pebble timeline API, a first version of a new app must be uploaded to the Developer Portal. This is required so that the appstore can identify the app's UUID, and so generate sandbox and production API keys for the developer to push pins to. It is then possible to use the timeline web API in sandbox mode for development or in production mode for published apps.
In the Developer Portal, go to the watchapp's details page in the 'Dashboard' view and click the 'Enable timeline' button.
To obtain API keys, click the 'Manage Timeline Settings' button at the top-right of the page. New API keys can also be generated from this page. If required, users with sandbox mode access can also be whitelisted here.
The sandbox mode is automatically used when the app is sideloaded using the SDK. By default, sandbox pins will be delivered to all users who sideload a PBW.
The production mode is used when a user installs the app from the Pebble appstore. Use the two respective API key types for these purposes. If whitelisting is enabled in sandbox mode, the developer's account is automatically included, and they can add more Pebble users by adding the users' email addresses in the Developer Portal.
If preferred, it is possible to enable whitelisting to limit this access to only users involved in development and testing of the app. Enter the email addresses of users to be authorized to use the app's timeline in sandbox mode on the 'Manage Timeline Settings' page of an app listing.
When whitelisting is enabled, the
Pebble.getTimelineToken()will return an error for users who are not in the whitelist.
