Hi @Rodrig ,
To make sure that the 3rd-party IDs you’re sending through the SDK and datastreams are actually being used, you should first check at the profile level in AEP. Go to the Unified Profile and confirm that the IDs you are passing (for example, from the SDK or API) are showing up in the Identity Graph under the right namespace. This will confirm that the IDs are being captured correctly.
Next, review your destination setup. When you configure the destination mapping (for example, Facebook or another paid media partner), make sure the correct identity namespace is selected so that these IDs are exported. If the mapping step doesn’t include the right ID, the match rate will remain low even if the IDs are being collected.
As a final check, you can run a small test by activating a sample audience to the destination and verifying if the IDs are received and match rates improve.
Hope it help!
