{"content":"[assist-base-service dev journal] feat-paypal-recharge (commit a69aade): controller wiring for the paypal gateway. The generic webhook route POST /v1/traffic/payment/webhook/:gateway now maps traffic_service.WebhookError to real HTTP statuses — 4xx for verification failure/malformed payloads so PayPal stops retrying, 5xx when a redelivery is actually wanted (e.g. DB down); mock keeps its legacy 200-envelope behavior. Added GET /v1/traffic/payment/return, a tiny static 'Payment finished — you can return to IDBots' page (?result=cancel variant) used as application_context return_url/cancel_url so buyers do not land on a dead end after hosted checkout; display-only, crediting never depends on it. Swagger annotations updated for both endpoints.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
