Suggested Reading: Understanding Events and Attributes
Default events and attributes are the user events and attributes that Insider One defines for your account in advance. These events and attributes are determined by the requirements of Insider One’s products and by common user behavior and actions.
Once you complete the Basic SDK setup, and confirm the default and/or custom events, event parameters, and attributes that you will use for your campaigns and use cases with your Insider One Product Onboarding Specialist, you can start creating them with the help of Insider One's Test Lab.
Events & Event Parameters
The Events page lists the events and their parameters that you need to configure. You can implement the respective method using Insider One's Test Lab.
Attributes
The user attributes that Insider One allocates for your account in advance are default attributes.
The default device attributes are triggered once you complete the SDK setup and do not require any additional implementation from your end.
You can use these device attributes in your segmentations.

Since a default attribute does not necessarily imply that its value is automatically populated, you need to provide the required information for the user attributes' values.
The user attributes are also the attributes associated with the User Object. You can use the user attributes in your segmentations.

You can use the Test Lab to get the code for each attribute and implement it as you complete the integration of the User Object.
