Setting Up Sources - Zeotap docs

The following are the best practices and recommendations that must be considered when using Sources:

For information on best practices to be followed while setting up different sources, refer here.
Verify the sample data provided by the customer for nested or complex structures. Presently, this data type is not supported. If ingestion is necessary, the customer must flatten the data on their end.
For Server to Server aka HTTP API sources, the data formats may need to be transformed.
Consider the Events vs Profiles vs other attribute types carefully when defining custom fields based on the customer’s use-case and specified data type. For information on Catalogue fields, refer here.
For Deltas, you must only share the updated data to ensure optimal use of processing allowance.
