Event Schemas

Event schemas define how Appier reads, displays, and processes tracked events. Each event schema describes an action and its properties, ensuring your data is consistent across all reports, segments, and user profiles.

Note

For accounts with AIRIS enabled, see System Event Schema for the full list of pre-built schemas.

To view and manage your event schemas, go to Common settings > Data management, then select Event schema.

Create an event schema

You can modify an existing schema to rename a schema, update its description, or modify its properties at any time. If none of the system event schemas cover your tracking needs, you can wait for auto-generation from your incoming data or follow these steps to create a custom event schema.

📘

Prerequisite

Creating and editing schemas requires Admin permission. Contact your customer support manager if you don't have access.

1. In the Common settings > Data management > Event schema, click + Add event schema.

2. In the Schema info section, enter the schema and select an Event type.

3. In the Event properties section, expand the New property panel, then click + Add property for each additional property. You can optionally toggle the Formula and Sensitive information.

4. In the Event template section, create a readable sentence with dynamic variables that populate automatically when you view an individual user's timeline or event history.
5. Click Create to save the schema.

Schema info

Use the Schema info section to define the schema-level details of the event itself.

• Event schema keys are case-sensitive. Accepted characters are uppercase and lowercase letters, numbers, underscores, dashes, and spaces.
• After you enter a key, click the AI icon on the placeholders of the schema name and description fields to generate human-readable metadata automatically. These semantic hints help your team quickly understand how the field can be used for segmentation and reporting without needing technical interpretation.

🚧

Important

Use caution when updating the Schema key value of an existing event schema. Changing it without updating the code will create duplicate events in your schemas.

Event properties

Use the Event properties section to define the individual data points collected when the event occurs. Configure the following fields for each property within a schema.
