PTTAvm Connector

Key Features Hand-built SOAP transport: SOAP 1.1 envelopes and the WS-Security UsernameToken header are constructed with ``requests`` + ``lxml`` only — no ``zeep``/``suds`` dependency. Endpoint ws.pttavm.com:93/service.svc. Order Sync (pull): a cron pulls orders for the last 24h via ``SiparisKontrolListesiV2`` (date window), maps the buyer + lines, and resolves the exact product variant by VariantBarkod / attribute values. Product Push (with variants): "Push to PTTAvm" submits the product via ``StokGuncelleV2`` as one StokKontrolDetay carrying header fields (category, brand, VAT, dimensions, cargo profile, JPEG image URLs) plus a VariantListesi of per-variant rows (VariantBarkod, Variant1Deger/Variant2Deger, Miktar, Fiyat). PTTAvm's two-axis variant model is mapped per product. Stock & Price Sync: ``StokFiyatGuncelle3`` refreshes stock and price for synced products, manually or via an hourly cron (off by default). Barcode Check: ``BarkodKontrol`` checks whether a barcode already exists. Categories & Cargo Profiles: pull the PTTAvm category tree (``GetCategoryTree``) and the seller's cargo profiles (``GetCargoProfiles``). Invoice linking: attach a posted invoice to a PTTAvm order (``SaveInvoince``) — BYOK linking only, no money movement / no clearance. JPEG images: a controller serves product images as baseline JPEG (PTTAvm rejects Odoo WebP), never webp. Currency conversion: prices converted to the configured marketplace currency (default TRY) before push. API Logs: every SOAP call is logged with operation, duration, status and error excerpt. Test Connection: a Settings button calls ``GetVersion`` to verify keys.
