Support for location triggered notifications can be achieved in the following ways.

📘

Radar and Plot Projects Integration

We have also partnered with Radar and Plot Projects if you want to integrate with their service.

Target By Country

Country is automatically tracked based on the IP Address. Use the country Data Filter in Segments or API Filters.

Target By City or Provided Location

OneSignal does not provide a way to track city or area codes. However, if your app/site collects this data, you can send it to OneSignal in the form of Data Tags.

Generally your app/site can collect this data in the following ways:

• User inputs a city or location into a field on your site/app.
• Prompt User for Location Tracking on Web and use Google Maps Reverse Geocoding API. Here is a great Medium Post about this.

Target By Latitude and Longitude

If your Mobile App collects location data, OneSignal will automatically update the latitude and longitude for the device. You can ask for location tracking permission through our Location Opt-In Prompt or use our promptLocation SDK Method.

Once location is set, messages can be sent based on a radius around the location point using the location Data Filter in Segments or API Filters.

Web Push Latitude and Longitude Tracking

OneSignal does not automatically collect location points on web push. You can setup your site to prompt users for Location Tracking and add Data Tags to set it within OneSignal. Here is a great Medium Post about this.

If getting and setting the location points with OneSignal sendTags method, assign "longitude" and "latitude" tags. For example, you could set "long"="37.160" and "lat"="-117.773".

Then you can send a message to users in a segment based on these tags.

For example, define a segment with tags "long" > 37, "long" < 38, "lat" > -118, "lat" < -117 to create a square target region containing users with location tags in that range.

You can do this manually via the New Messages Page, automatically via the Server REST API, or automatically via the Automated Messages Page.

FAQ

How often does the OneSignal SDK update location points?

Depending on the location permissions you set in the app, the location will get updated when the app is open in the Foreground/background or continuously when the app is closed.

For iOS location settings, see the Apple Developer Guide for Choosing the Location Authorization Level

For Android location settings, see the Android Developer Guide on Location Permissions

Starting with android 8, they limit background updates to "a few times every hour", in our tests, this appears to be 4 times per hour.

On our end, we might change how often we update this information from time to time for optimization reasons but currently we check the user's location around every 5 minutes.
