We are excited to announce that Actions Transaction Metadata is now GA.
This feature allows you to set, share, and access, custom data between Actions run in the same post-login execution.
Functionality includes:
event.transaction.metadata object within post-login Actions that contains the custom key/value pairs, which can be accessed through key.api.transaction.setMetadata function within post-login Actions that serves as interface to set the custom key/value pairs.boolean, number, string, or string serialization of object and array.Fetched April 14, 2026
