Character Limits and Filtering

1 Overview

To ensure data consistency and prevent processing issues, Mapp Intelligence applies certain limits and formatting rules to incoming values. This includes restrictions on request size, data types, and automatic filtering of unsupported characters.

These rules apply to all tracking data and cannot be customized.

2.3 Filtered Characters During Processing

During tracking data processing, specific characters are automatically removed or normalized to ensure clean input. These transformations happen before the data appears in reports or exports.
