User-defined reports are custom reports where you, as the user, can select the dimensions and metrics you want to retrieve from LinkedIn Advertising API.
When you select a user-defined report, you will see additional fields in the interface.
To build this type of report, you need to define the required dimensions, metrics, and pivot yourself. Here is some guidance on how to do that.
1. How to define dimensions and metrics
You can define any required for your business case metrics to be used in connector. To get more insights about available metrics, follow this documentation.
In order to select required dimensions, you need to define your pivot first (see p.2 below ‘How to define pivot'). For example, if you select CREATIVES as a pivot, you will have access to the fields explained in the schema here.
2. How to define a pivot
In the given context, a 'pivot' refers to the process of reorganising or summarising data in a report by grouping it based on specific criteria. For example, pivoting by CAMPAIGN will group the results by campaign. Learn more about available pivots here.
