Core metrics
Core metrics are the criteria that define a mini app's active users and core target actions. Based on these metrics, we find and recommend users who are likely to like our app. The better the core metrics are set up, the greater the chance the app has to be shown to more suitable users.
Why set key metrics
Exposure and recommendation optimization: Find users similar to active users, and expose and recommend our app to users who are likely to like it.
Performance analysis: You can check not just one-time visits, but how much the number of users who actually return frequently is increasing.
Operations and improvement: It also serves as a standard for internal agreement within partner companies on “what the key metrics are.”
Set up in the console
Apps in Toss Console → Select workspace → Select mini app → Select 'Key Metrics' from the left menu.

Active metrics
Active metrics are the criteria for defining users who use my app frequently. You can set only one per app.
Active metrics are used like this.
Exposure and recommendation: Toss finds users similar to active users and exposes and recommends our app to users who are likely to like it.
Performance analysis: You can check not just one-time visits, but how much the number of users who actually return frequently is increasing.
1) Choose a template
You can choose from 3 templates. After selecting one, enter the desired values and register it right away.
2) Build it yourself
If there is no template you want, you can set a custom event as an active metric.
Metric name: Write it so the team can distinguish it and see what metric it is.
Description: Write a short description so the metric can be understood at a glance.
You can combine events with OR conditions and define parameters as well.
Conversion metrics
Conversion metrics are the criteria for defining the user actions you most want to track in a mini app (core goal actions). Rather than simply launching the app or viewing screens, it’s better to use as conversions the moments that are closer to the service’s purpose (e.g. completing signup, completing the first payment, consuming core content, etc.). You can register up to 3 conversion metrics.
1) Choose a template
The Toss team has prepared commonly used metrics as templates. You can register them right away by simply selecting one.
2) Build it yourself
Metric name: Write it so the team can distinguish it and see what conversion it is.
Description: Write a short description so the metric can be understood at a glance.
You can combine events with OR conditions and define parameters as well.
If there is no template you want, you can select 'There is no metric I want' below the list and request the needed metric from the Toss team.

Primary conversions and secondary conversions
Among conversion metrics, you can have only one primary conversion.
Primary conversion: The conversion this mini app prioritizes the most. It becomes the default metric used for optimization and analysis such as exposure and recommendation.
Other conversions: Metrics used to view the process leading up to the primary conversion together.
For example, if the primary conversion is payment completion, you can set add to cart and payment attempt as secondary conversions to see at which stage users drop off.
The first conversion metric you create is automatically set as the primary conversion. If you want to change it, you can select another conversion metric and check it as the primary conversion.
Please be sure to check
The changed metric will be applied starting the next day.
Key metrics are used as the basis for exposure, recommendation, and performance analysis, so please set them carefully.
Check metrics
You can view the registered key metrics as charts on the list screen.
You can view data by selecting the date range and time unit at the top (daily, weekly, monthly).
Active metrics show the number of active users, and conversion metrics show the number of converted users.
