As part of our platform migration, the data source used for exports is evolving. This page explains what stays the same and what will change for your exports, whether they run through the Export API or as a custom export.
We've done compatibility work to guarantee full continuity of your exports:
your exports keep running with no interruption;
the format of the files and responses stays identical;
no action is required on your side to maintain your existing flows.
This remains true even after the legacy installation bases (MEP/legacy) are retired and the v1 push is discontinued.
Starting [DATE — TBD], the data source for exports will switch from the installation base to the Profiles base. The flow and format are preserved, but this change of source introduces a few functional differences to anticipate.
The Advertising ID (IDFA/GAID) is no longer indexed in the new source, so the corresponding field will always be returned empty in your exports.
Smart Segments are no longer available for export and will return empty values.
The number of exported profiles (both API and custom exports) will likely decrease. By default, the Profiles base only retains profiles active over the last 13 months; profiles that have been inactive for longer are no longer included in exports. This retention period (TTL) is configurable on request — contact your CSM if you need a longer window.
This change takes effect on [DATE — TBD]. Until then, nothing changes for your exports.
For any question about the impact on your use case, or to adjust the retention period, reach out to your CSM.
