It will be useful for this use case where I’m using Stape Store to enrich a webhook with fbc, fbp and other Meta-related attribution parameters.
Now, I can achieve that only for new customers.
Once I’ll have the option to set my own document key, I will be able to use it in order to map previous customers and enrich it with relevant parameters for them too.
We plan to add this early next year.
But you can store user identifiers inside documents as fields and searching by queries rather than by document name.
