# @root/paypal-checkout In contrast to the official PayPal Checkout SDK - which is auto-generated code with lots of abstraction without much value - this is very little abstraction, but specificially designed to be (mostly) idiomatic JavaScript / Node.js. \ (excuse the `snake_case` - that's how the PayPal REST API is designed). ![](https://i.imgur.com/brFTseM.png "PayPal Checkout API Flow") Check out with PayPal The Good Documentation™ for the PayPal API (a.k.a. PayPal Checkout SDK) is the "REST API". See - (one-time payments) - (recurring subscriptions) - (the buttons) # Install ```bash npm install --save @root/paypal-checkout ``` # Usage ```js "use strict"; require("dotenv").config({ path: ".env" }); let PPC = require("@root/paypal-checkout"); PPC.init({ client_id: "xxxx", client_secret: "****", }); PPC.Subscriptions.createRequest({ // See https://developer.paypal.com/docs/api/subscriptions/v1/#subscriptions }); ``` # API ```txt PayPal.init(client_id, client_secret, 'sandbox|live', defaults); PayPal.request({ method, url, headers, json }); PayPal.Product.create({ ... }); // event_type: "CATALOG.PRODUCT.CREATED" PayPal.Product.list(); PayPal.Product.details(id); PayPal.Product.update(id, { description }); // event_type: "CATALOG.PRODUCT.UPDATED" PayPal.Plan.create({ ... }); // event_type: "BILLING.PLAN.CREATED" PayPal.Plan.list(); PayPal.Plan.details(id); PayPal.Plan.update(id, { description }); // event_type: "BILLING.PLAN.UPDATED" PayPal.Subscription.createRequest({ ... }); PayPal.Subscription.details(id); PayPal.Subscription.cancel(id, { reason }); ``` # Redirects Subscription Request `return_url` will include the following: ```txt https://example.com/redirects/paypal-checkout/return ?subscription_id=XXXXXXXXXXXXXX &ba_token=BA-00000000000000000 &token=XXXXXXXXXXXXXXXXX ``` # Webhooks Webhooks can be set up in the Application section of the Dashboard: - You'll see a list of applications. Click on one to access the webhooks. # Notes Note: Just about everything in the PayPal SDK that uses `ALL_CAPS` is a `constant`/`enum` representing an option you can pick from limited number of options. Sandbox accounts (for creating fake purchases) can be managed at: Note on Auth + Capture: > Authorization and capture enables you to authorize fund availability but delay > fund capture. This can be useful for merchants who have a delayed order > fulfillment process. Authorize & Capture also enables merchants to change the > original authorization amount in case the order changes due to shipping, > taxes, or gratuity. > > For any payment type, you can capture less than or the full original > authorized amount. You can also capture up to 115% of or $75 USD more than the > original authorized amount, whichever is less. > > See > > - > - Buttons: - <== THE ONE YOU WANT - Check out with PayPal - -
