Custom Identifiers

Managing custom identifiers

What are custom identifiers?

Custom identifiers enable you to load alternative identifier types into your DCN that aren't natively supported when using the tabular data schema to format your files and tables.

Examples of such IDs are Publisher Provided IDs (PPIDs), platform-specific IDs, or other types of internal ID types that you want to use when building query audiences for audience sync & real time targeting via the Opable SDKs.

How to use custom identifiers

All customer identifiers are prepended with the letter c, and there are 20 slots from which you can create new customer identifier types. The ID slot values range from c to c19, which you will reference as headers when loading data into your DCN.

You can also assign each custom ID a "display name" which you can use to identify which custom ID is for which purpose. For example, if you have a PPID that you want to load into your DCN, you can use the custom ID c with the display name My PPID

In addition, custom identifiers are set as Person scope by default, but can be changed to Household scope if required.

Managing your Custom IDs

For example, to load a custom PPID into your DCN, you would then associate your PPID to the custom ID you chose, for example c by formatting your file or Snowflake table based on the tabular data schema with the header id_c in column one.

id_c
your custom PPID

Once this data is loaded, your custom PPIDs will then be available in your DCN for use in real time targeting and audience syncing.
