Not yet. Redbark connects to banks via Australia's Consumer Data Right (CDR / Open Banking) framework, which initially only covered traditional banks and ADIs. Because Amex operates as a credit card issuer, they were outside that scope.
The Australian Government updated the CDR rules in March 2025 to bring non-bank lenders like Amex into the framework, with that rollout starting in tranches from July 2026. Once Amex begin supporting Open Banking on their end, we should be able to add them later in 2026, though exact timing depends on how that rollout progresses.
