Makes client secret optional for Financial Connections Sessions
What’s new
The client_secret property is now optional on Financial Connections Sessions. Previously, the client_secret property was set on all Financial Connections Sessions. It will only be omitted for sessions created with a ui_mode value of hosted.
Impact
This change is backward compatible. Existing integrations continue to work because the client_secret is still provided for existing Financial Connections flows, and will only be omitted for net-new flows.
