Find out how you can reconcile your first-party data using first-id as a reconcilation key in Permutive.
You can leverage the cross domain/device capabilities of first-id as a reconcilation key for all your audience segments inside Permutive interface.
Permutive first-party data segments can also be imported in your adserver so you can seamlessly activate your audiences based on the first-id identifier.
How can I do that ?
Enable First-id collection via the Permutive dashboard
To see the different identifiers, follow these steps :
- Navigate to your workspace dashboard
- on the left, select ‘Settings
- at the top, select the ‘Login’ tab
To add First-id identifiers, follow these steps:
- Navigate to dashboard > ‘settings’ > ‘Identifiers’.
- Select ‘Add an identifier’ (both red and green buttons work)
- Add the tag for the first-id identifier. Click OK, and you’re done.
Set up the JavaScript collector to route identifiers to Permutive
💡 TIP : Installing/using our notre SDK can greatly simplify the process of retrieving the first-id identifier and passing it on to your adserver.
