Tags are one of the most useful tools Pushwoosh offers, enabling a range of sophisticated functionality. By using tags, you can segment your audience and send targeted push notifications to specific users based on their attributes.
Tags can contain any arbitrary data associated with a particular user or device. This data might include usernames, IDs, cities, favorite football teams, preferred news categories, or any other relevant information about your users.
Start by identifying your business needs and determining how you want to segment your audience. Consider factors such as age, location, in-app purchase history, or any other relevant criteria for targeting users.
Tag values can help you make your push campaigns smarter. Each tag is capable of storing nearly limitless number of values. Basically, this means that one tag would be enough to record a specific type of information about each end-user in your database.
There are only a few tags available for each account, but considering the nearly-infinite space for each tag, just a couple of tags are enough to gather an enormous amount of information about your users and set up very complex targeting patterns.
Integer — used for the integer data (amount of in-game cash acquired, level achieved, age).
String — used for string values (username, e-mail, identifiers).
List — the same as String type, but each user may have multiple values set simultaneously (music preferences, news categories, cuisine preferences).
Boolean — true / false type of Tag.
Date — used for calendar dates. Basically, this is an integer type tag which stores Unix Epoch timestamps (automatically converted from/into Gregorian date).
Price — allows to set values according to specified currency in the “*.XX” format Learn more.
Version — used for versioning. The example of allowed format is w.x.y.z (Major.Minor.Patch.Build). Max value for each version part is 9999, so the max version number cannot be greater than 9999.9999.9999.9999.
Each Tag type has a specific set of operators applicable. Tag operators define the relationship between the Tag and its values for segmentation purposes.
Integer Tag operators: is, is not, are, not in, not set, any
String Tag operators: is, is not, are, not in, not set, any
List Tag operators: in, not in, not set, any
Boolean Tag operators: is (true/false), not set, any
Date Tag operators: exactly on, on or after, on or before, between, not set, any
Price Tag operators: is, is not, greater or equals, less or equals, between, in, not in, not set, any
Version Tag operators: is, is not, greater or equals, less or equals, between, in, not in, not set, any
When creating a tag, you choose how its values are stored:
General (default, user_specific: false): the tag value is stored per device (HWID). Each device of the same user can hold a different value independently.
User-specific (user_specific: true): the tag value is stored per user (UserID). When set via UserID, the value is applied to all of the user’s devices at once. Useful for attributes that belong to the person, not a particular device: subscription tier, loyalty points, preferred language.
A user has both the iOS and Android versions of your app installed. Setting a subscription_tier tag to "premium" via their UserID applies it to both devices immediately. With a General tag you would need to set it per device separately.
These tags are available by Pushwoosh out-of-the-box, so you don’t have to (and, in fact, should not) set them manually. Most of them are set from the application and sent over to our server via registerDevice and other API calls, and some are set by the server itself.

This is where your creativity comes in to achieve your specific business goals. Custom tags can be created based on the segmentation logic or targeting pattern that is appropriate for your unique business needs. Collaborate with your marketing team to define the additional custom tags necessary for your campaigns.
When true, the tag value is stored at the user level and shared across all of a user’s devices when set by UserID. When false (default), the tag is device-level and set per HWID.
While in most cases (99%), tags are set from the application, you can also set tags via Pushwoosh API. Below is an example of a typical request to the /setTags endpoint:
Device’s location is determined based on its IP address at the moment your app was launched on that device for the last time. GeoIP submits the location data to Pushwoosh, and Pushwoosh saves the location received from GeoIP as a City tag value for a particular device.
In some cases, the location submitted by the GeoIP differs from the city name — for example, when it refers to an area of a city or other administrative unit. Please be careful when using the default City tag for segmentation purposes: make sure to select the proper values.
For example, if you’re going to target users from Munich, you have to cover it with a bunch of City tag values, including “Munich” itself (with all the corresponding values, such as different variants of spelling which could be returned by GeoIP and saved as tag values) and several nearby areas.
