پیمنٹ سکرپٹ کی مثالیں

پیمنٹ سکرپٹس پیمنٹ گیٹ ویز کے ساتھ تعامل کرتے ہیں، اور کسی گیٹ وے کا ٹائٹل، مرئیت، اور ڈسپلے پوزیشن تبدیل کر سکتے ہیں۔ جب بھی آپ کا کسٹمر چیک آؤٹ پر پیمنٹ کے طریقے کے صفحے تک رسائی حاصل کرتا ہے تو یہ سکرپٹس چلتے ہیں۔ پیمنٹ سکرپٹس ایکسلریٹڈ چیک آؤٹس کے ساتھ تعامل نہیں کرتے، کیونکہ ایکسلریٹڈ چیک آؤٹس آپ کے کسٹمرز کو ان کے چیک آؤٹ کے صفحے تک پہنچنے سے پہلے ہی دکھائے جاتے ہیں۔

اس صفحے پر موجود ٹیمپلیٹس استعمال کرنے کے لیے، بلینک ٹیمپلیٹ کے ساتھ ایک نیا سکرپٹ بنائیں۔

اقدامات:

  1. اپنے Shopify ایڈمن سے، ایپس > Script Editor پر جائیں۔

  2. سکرپٹ بنائیں پر کلک کریں۔

  3. پیمنٹ گیٹ ویز پر کلک کریں۔

  4. Blank template کو منتخب کریں، پھر Create script پر کلک کریں۔

  5. Ruby source code سیکشن میں، کوڈ کی ڈیفالٹ لائن کو حذف کریں: Output.cart = Input.cart

  6. اس صفحے سے ایک اسکرپٹ کاپی کریں اور اسے Ruby source code سیکشن میں پیسٹ کریں۔

  7. اسکرپٹ کے Customizable Settings سیکشن میں ترمیم کریں تاکہ یہ آپ کے سٹور میں کام کرے۔

  8. اپنے اسکرپٹ کی جانچ کریں۔ مزید معلومات کے لیے، Shopify Scripts کی ٹیسٹنگ اور ڈیبگنگ دیکھیں۔

  9. ٹیسٹ کرنے کے بعد:

    • اسکرپٹ کا غیر شائع شدہ ڈرافٹ محفوظ کرنے کے لیے Save draft پر کلک کریں، یا
    • اسکرپٹ بنانے اور شائع کرنے کے لیے Save and publish پر کلک کریں۔

مخصوص کسٹمر کے لیے گیٹ وے دکھائیں

یہ اسکرپٹ استعمال کریں تاکہ مخصوص طور پر ٹیگ کردہ کسٹمر کو صرف ایک مخصوص گیٹ وے کا آپشن دکھایا جا سکے۔

مثال کے طور پر، VIP ٹیگ والے کسٹمر کو صرف ایک مخصوص گیٹ وے دکھائیں - کسی بھی دوسرے کسٹمر کے لیے گیٹ وے چھپا دیا جائے گا۔
