+# Payments
+
+A payments app for frappe.
+
+## Installation
+1. Install [bench & frappe](https://frappeframework.com/docs/v14/user/en/installation).
+
+2. Once setup is complete, add the payments app to your bench by running
+    ```
+    $ bench get-app payments
+    ```
+3. Install the payments app on the required site by running
+    ```
+    $ bench --site <sitename> install-app payments
+    ```
+
+## App Structure & Details
+App has 2 modules - Payments and Payment Gateways.
+
+Payment Module contains the Payment Gateway DocType which creates links for the payment gateways and Payment Gateways Module contain all the Payment Gateway (Razorpay, Stripe, Braintree, Paypal, PayTM) DocTypes.
+
+App adds custom fields to Web Form for facilitating payments upon installation and removes them upon uninstallation.
+
+All general utils are stored in [utils](payments/utils) directory. The utils are written in [utils.py](payments/utils/utils.py) and then imported into the [`__init__.py`](payments/utils/__init__.py) file for easier importing/namespacing.
+
+[overrides](payments/overrides) directory has all the overrides for overriding standard frappe code. Currently it overrides WebForm DocType controller as well as a WebForm whitelisted method.
+
+[templates](payments/templates) directory has all the payment gateways' custom checkout pages.

+# Integrating PayPal
+
+### 1. Validate Currency Support
+
+Example:
+
+	from payments.utils import get_payment_gateway_controller
+
+	controller = get_payment_gateway_controller("PayPal")
+	controller().validate_transaction_currency(currency)
+
+### 2. Redirect for payment
+
+Example:
+
+	payment_details = {
+		"amount": 600,
+		"title": "Payment for bill : 111",
+		"description": "payment via cart",
+		"reference_doctype": "Payment Request",
+		"reference_docname": "PR0001",
+		"payer_email": "NuranVerkleij@example.com",
+		"payer_name": "Nuran Verkleij",
+		"order_id": "111",
+		"currency": "USD",
+		"payment_gateway": "Razorpay",
+		"subscription_details": {
+			"plan_id": "plan_12313", # if Required
+			"start_date": "2018-08-30",
+			"billing_period": "Month" #(Day, Week, SemiMonth, Month, Year),
+			"billing_frequency": 1,
+			"customer_notify": 1,
+			"upfront_amount": 1000
+		}
+	}
+
+	# redirect the user to this url
+	url = controller().get_payment_url(**payment_details)
+
+
+### 3. On Completion of Payment
+
+Write a method for `on_payment_authorized` in the reference doctype
+
+Example:
+
+	def on_payment_authorized(payment_status):
+		# your code to handle callback
+
+##### Note:
+
+payment_status - payment gateway will put payment status on callback.
+For paypal payment status parameter is one from: [Completed, Cancelled, Failed]
+
+
