On this page: Learn how administrators connect a sandbox to an Adobe Experience Manager repository, setting author-only or publish access, custom domains, and authentication, so marketers can use AEM Content Fragments in their journeys and campaigns.
Adobe Journey Optimizer integrates with Adobe Experience Manager as a Cloud Service and Adobe Experience Manager Managed Service so you can use Content Fragments in Journeys and Campaigns. Content Fragments are read from the Adobe Experience Manager publish repository by default, administrators can switch to author-only or adjust publish access in the AEM Integration menu.
➡️ When the repository is configured, continue with Work with Experience Manager Content Fragments for authoring and selection tasks in Journey Optimizer.

Journey Optimizer stores one integration per organization, sandbox, and Adobe Experience Manager repository. If you save a new integration for that same combination, it replaces the previous settings, only the latest configuration is kept.
To configure your repository:
-
Access Administration > Channels > AEM Integration.
-
Click Create configuration.
-
If you use Adobe Experience Manager Managed Services, enter a repository hostname ending with
adobecqms.netin the Custom AMS Repo ID field.
-
If you use Adobe Experience as a Cloud Service, choose which repository to configure and click Next.
Additionally, you can click View to access this repository.

Choose your setup:
accordion Author only setup Select Author only setup when Journey Optimizer should read Content Fragments from the Adobe Experience Manager author environment only. Replication from author to publish and live publish updates are not supported.
accordion Publish instance setup By default, every Adobe Experience Manager as a Cloud Service repository is configured to use the publish instance. You can continue to the Content Fragment test step without changing these settings.

Select Publish instance setup to turn on publish instance settings.
-
Enable Send token to publish instance so service credentials are included with requests to the publish instance.
