Overview
This check validates that your Adobe Experience Platform (AEP) tags, deployed via the AEP Web SDK, are successfully communicating with the Adobe Experience Platform Edge Network.
A "Success" response status code confirms that the Edge Network has received the XDM (Experience Data Model) data, validated it against your schema, and is prepared to route it to your configured datastreams.
Why it is important
Monitoring for success status codes is critical for maintaining data integrity and ensuring downstream services receive accurate information:
Data Loss Prevention: A non-success code (like 400 or 403) means the data never reached the Adobe Edge Network, leading to "dark" periods in your reporting and audience building.
XDM Schema Validation: AEP is strict. If your tag sends data that doesn't match your XDM schema, the Edge Network will reject the hit. A success code confirms your schema mapping is correct.
Datastream Reliability: Success status ensures that your Datastream ID are correctly configured and authorized to send data.
Real-time Personalization: A failed tag status means the user will not receive a personalized experience, often defaulting to a "control" or broken layout.
Implementation
We have made implementing this check for AEP Tags simple.
The primary pre-requisite step is to create an Audit that scans the pages you want to validate.
Then, check the pre-built ObservePoint report for Pages with AEP tag status code failures.
ObservePoint identifies three primary success indicators:
200 OK: The standard success response indicating the Edge Network accepted the request.
207 Multi-Status: Indicates the request reached the Edge, but one or more downstream services (e.g., Adobe Target) may have failed.
204 No Content: Typically seen in "collect" calls where no response body is required.
Remediation
If your AEP tags are returning error codes (4xx or 5xx), investigate the following common configuration gaps:
Check XDM Mapping: Review the browser console or Adobe Experience Platform Debugger for "Validation Errors." Ensure that the required fields in your XDM Schema are present and use the correct data types.
Verify Datastream ID: Ensure the
configIdin your Tag extension matches the Datastream ID in the AEP Interface for the correct environment (Development, Staging, or Production).Review Permissions: Confirm that the technical account or environment has the necessary permissions to write to the specified AEP Sandbox.
CORS and Domain Settings: Ensure your domain is "allow-listed" if you are using a first-party CNAME for your Edge Network endpoint.
Status Code | Meaning | Remediation Step |
400 Bad Request | XDM Validation Error | Verify the payload matches the AEP Schema requirements. |
403 Forbidden | Authentication Error | Check that the Datastream ID is correct and active. |
207 Multi-Status | Partial Success | Check the "destinations" in the response body to see which service failed. |
413 Payload Too Large | Size Limit Exceeded | Reduce the size of the XDM object being sent in the request. |
Conclusion
As organizations move toward the Adobe Experience Platform, the complexity of tag validation increases. A success status is no longer just about a "pixel firing"; it is about the successful handoff of structured data to a global edge network.
By using ObservePoint to monitor for "Success" status codes, you ensure your data foundation remains robust and your personalization engines remain active.
