# Custom Event Schemas
## Custom Event Schemas
In this section, you can build your customized Event schemas which can be used later to set [Event-based Campaigns](https://help.openloyalty.io/main-features/custom-events/broken-reference) - the one which you will pick during creation, in the 'Event name' one of the created custom Event schema, and which are triggered by custom Events - based on custom Event schemas.
To access **Custom Event schemas** go to the **Custom Events** under the **Members** panel. Here you will see all the events presented in the table.

#### Fields available when creating Custom Event Schema:

The attribute can be used when creating an Event-Based campaign that determines the receipt of Units.
Available attribute types:
* **Boolean** - true/false
* **Datetime** - e.g. "2024-03-08T02:02:08+01:00"
* **Number**
* **Text** - 'string'
#### Filtering Custom event schemas
When there are a lot of records, you can change the number of rows displayed per page by clicking on the arrow icon below the table and picking a handy number from the list. You can also filter the results by clicking on the **ADD FILTER** button and picking a suitable option from the list:
* Active
* Create date
* Event name
* Event system identifier
the In Filter pop-up screen you will choose the *Property* mentioned above along with condition and value, after filling it up click on the 'Add filter', and only records fulfilling such criteria will be displayed.
Besides searching via filters you can use a Search Table available in the upper right corner under the 'Add Event Schema' button. The search field allows you to find the event schema via the name:
