VersionDescription

0.9.78.02

OAuth Self-Healing & Status Polling

Fixed orphaned OAuth credentials from Pro-to-Lite transitions. Replaced popup.closed polling with gateway status polling for reliable cross-browser OAuth connections. Moved account name fetch from oauth/finish to validate_key for faster OAuth completion.

Improvements (3)
  • OAuth popup detection replaced with gateway status polling for reliable cross-browser support
  • Account name now fetched during API validation instead of separate HTTP call during OAuth finish
  • validate_key uses /3.0/ root endpoint instead of /3.0/ping — same cost, returns account metadata
Fixes (3)
  • Fixed orphaned OAuth state when switching between Pro and Lite — encrypted credentials detected and restored automatically
  • Fixed submission handler skipping OAuth-connected forms missing auth_type in config
  • Fixed Pro field sync and submission handler not resolving OAuth API keys
