Linking embed codes primarily applies to Dynamic Tag Management (DTM) and Adobe Experience Platform Launch users who use built-in Akamai hosting. Those who are self-hosting, please see the self-hosting section at the end of this article.
A DTM embed code is a
<script> tag that you embed in the HTML of your web page.
DTM publishes this container tag file to the web host you specified, which is either an Akamai location or your own FTP location. The embed code that DTM provides is based on this host location.
When a user visits your site in a browser, the browser requests the DTM file from this server, using the embed code, and loads it.
In the diagram below, Step 1 shows DTM publishing the container tag to your specified web host. In Step 2, the browser requests the container tag, using the embed code, and the host responds with the published file.
The linking process allows you to take the DTM Production embed code, with its matching host location, and use that same embed code with your Platform Launch production environment.
If you do this, DTM and Platform Launch share the server location and the container tag file name.
When you publish in Platform Launch , the Platform Launch container tag file overwrites the DTM file, so when the browser requests the file from the server, the Platform Launch file is returned.
In the diagram below, Step 3 represents Platform Launch publishing its container tag over the top of the DTM container tag (from Step 1). When Step 2 occurs, it gets the Platform Launch container tag instead.
This overwriting works both ways. If you publish Platform Launch , then subsequently publish from DTM, the DTM container tag overwrites the Platform Launch one. You have two systems publishing to the same location. This means you don’t have to change the code on your page, but it also means you need to be careful when you publish. It’s recommended that you disable your DTM property to prevent this situation.
Before you link your embed code:
Platform Launch validates a number of things and tells you whether linking was successful.
You can only have one Production environment in Platform Launch . If you have already created one on this property, you need to delete the existing Production environment so you can create a new linked environment. The new one does not have the same embed code as the old one, so don’t do this unless you are familiar with the process.
If you use embed code linking, the process is mostly the same as without it, but with some highlighted differences:
Step 7 can be done any time after Step 3 has been performed.
DTM also supports self-hosting of the DTM container tag file. There are two methods to accomplish this:
In either case, it doesn’t make much sense to migrate the embed code. Nothing will break if you try it. It’s recommended that you not use this option and set up your hosts and environments manually.
Due to the differences in setup between FTP and SFTP, DTM and Platform Launch cannot perform automated migrations of these settings.
If you are using this method for delivery of the container tag, it’s recommended that you move to SFTP in Platform Launch . You can create an SFTP host and use this for any environment that you choose.
In Platform Launch , downloading the library no longer exists as a separate option. If you use a library download in DTM, we recommend you skip the embed code migration and set up your Production environment with an Adobe Managed host and Archive enabled.
You can continue to use the same embed code that you use with DTM, but you are responsible for moving the library to your own servers with the correct file name.
