+# AISBF v0.99.27 - Payment System Final Status
+
+## ✅ COMPLETE - All Tasks Finished
+
+### Latest Changes (Just Completed)
+
+#### 1. API Tokens Link - Hidden for Config Admin ✅
+- **File**: `templates/base.html`
+- **Change**: Wrapped API Tokens link with `{% if request.session.user_id %}`
+- **Result**: Config admin (from aisbf.json) no longer sees API Tokens link

+  - PayPal configuration
+  - Stripe configuration
+  - Bitcoin configuration
