การสร้างผลิตภัณฑ์และราคาสำหรับแผนบริการ

Welcome to creating your subscription service! A key step is defining what you sell and how much it costs.

In Stripe, you'll use two main concepts for this: Products and Prices.

Think of them as the building blocks for any item or service you want to charge for, especially for recurring subscriptions.

A Product in Stripe represents the core item or service you're offering. It's the 'what' you're selling.

• It holds general information like the product's name (e.g., 'Pro Plan', 'Premium Support').
• It can also include a description and optional images.
• A product itself doesn't have a price; it's just the definition of the offering.

For subscriptions, a product often represents a specific tier or plan.

A Price in Stripe defines how much a product costs and how it's billed. This is the 'how much' and 'how often' of your offering.

• It specifies the amount (e.g., $10.00).
• It defines the currency (e.g., USD, EUR).
• Crucially for subscriptions, it sets the billing interval (e.g., monthly, yearly).

A single product can have multiple prices (e.g., monthly vs. yearly options for the same 'Pro Plan').

Products and Prices work together. A product is like a blueprint, and prices are the specific ways you can sell that blueprint.

For example:

• Product: 'Premium Software Plan'
• Price 1: $29.99 USD per month
• Price 2: $299.99 USD per year

Both prices are linked to the same 'Premium Software Plan' product, offering different billing frequencies to your customers.

While you can create products in the Stripe Dashboard, using the API gives you programmatic control. Let's create a simple product using Python:

Note: This code demonstrates the API call structure. It requires a real Stripe API key to actually create resources.

Now that we have a product, let's create a recurring price for it. This price will define the monthly cost.

You'll need the id of the product you just created (or an existing one). Let's assume 'prod_ABCXYZ' for our example.

Stripe's pricing allows for flexible billing intervals to suit various subscription models:

• month: Billed every month.
• year: Billed every year.
• week: Billed every week.
• day: Billed every day (less common for SaaS, but available).

You specify the interval within the recurring object when creating a price.

You have two primary ways to manage your products and prices:

• Stripe Dashboard: Great for initial setup, viewing existing items, and making manual changes. Go to 'Products' in your dashboard.
• Stripe API: Essential for automation, integrating with your application, and dynamic price creation (e.g., for different customer segments).

For a scalable subscription service, the API will be your primary tool for management.

When defining products and prices:

• Clear Naming: Use descriptive names for your products and prices.
• Product Type: For subscriptions, usually set type='service'.
• Price IDs: Stripe assigns unique IDs (e.g., prod_ABCXYZ, price_123DEF). Store these IDs in your application's database to reference them when creating subscriptions.

These IDs are crucial for linking your customers to the correct subscription plans.

Great job! In this lesson, you learned the foundational concepts of Stripe Products and Prices:

• Products define the items or services you sell (e.g., 'Basic Plan').
• Prices define the cost, currency, and billing frequency for a product (e.g., '$10/month USD').
• You can create and manage both using the Stripe API for programmatic control.

Understanding these concepts is crucial for building any subscription-based business with Stripe. Next, you'll learn how to let customers manage these subscriptions!
