Frequently Asked Questions

What are the main business benefits of using this Stripe Subscription API template?

The Stripe Subscription API template offers several key business advantages: - Flexible pricing: It's compatible with any price point set up in Stripe, allowing for easy adjustment of subscription tiers. - UTM tracking: The template captures UTM parameters, enabling better tracking of marketing campaigns and their effectiveness in driving subscriptions. - Scalability: Built on FastAPI, the template can handle high volumes of subscription requests efficiently. - Easy integration: The template provides front-end integration instructions, making it simple to implement in various web applications.

How can this template help with subscription management for SaaS businesses?

For SaaS businesses, the Stripe Subscription API template streamlines subscription management by: - Automating the subscription creation process - Handling secure payment processing through Stripe - Providing a standardized way to create subscriptions across different products or tiers - Offering flexibility in subscription duration (through the 'months' parameter) - Enabling easy tracking of subscription sources through UTM parameters

Can this template be used for one-time purchases as well as subscriptions?

While the Stripe Subscription API template is primarily designed for recurring subscriptions, it can be adapted for one-time purchases. However, this would require modifications to the code. The current implementation creates a Stripe Subscription object, which is intended for recurring payments. For one-time purchases, you would need to implement a separate endpoint that creates a Stripe PaymentIntent or Charge instead of a Subscription.

How can I modify the template to include additional customer information in the subscription creation process?

To include additional customer information, you can modify the Data class in the template. For example, to add a customer's name and email, you could update the class like this:

python class Data(BaseModel): months: int = Field(..., gt=0) utm_source: str = '' utm_medium: str = '' utm_campaign: str = '' utm_term: str = '' utm_content: str = '' price: str = Field(..., min_length=3) customer_id: str = Field(..., min_length=3) payment_method: str = Field(..., min_length=3) customer_name: str = Field(..., min_length=1) customer_email: str = Field(..., min_length=5)

Then, in the create_subscription function, you can use this information when creating the subscription or updating the customer:

python stripe.Customer.modify( data.customer_id, name=data.customer_name, email=data.customer_email )

How can I implement error handling for failed subscription creations in the front-end?

To handle errors in the front-end when using the Stripe Subscription API template, you can modify the create_subscription function in the provided JavaScript. Here's an example of how you could implement error handling:

```javascript async function create_subscription() { try { const months = 1; const utmParams = getUTMParameters();

       const response = await fetch("YOUR SERVER LINK/create-subscription", {
           method: "POST",
           headers: {
               'Content-Type': 'application/json'
           },
           body: JSON.stringify({
               months,
               price: 'PRICE_ID',
               customer_id: 'CUSTOMER_ID',
               payment_method: 'PAYMENT_METHOD_ID',
               ...utmParams
           })
       });

       if (!response.ok) {
           const errorData = await response.json();
           throw new Error(errorData.detail || 'Subscription creation failed');
       }

       const { subscriptionId } = await response.json();
       console.log('Subscription created successfully:', subscriptionId);
       return subscriptionId;
   } catch (error) {
       console.error('Error creating subscription:', error.message);
       // Handle the error (e.g., display an error message to the user)
       throw error;
   }

} ```

This implementation checks if the response is successful, and if not, it throws an error with the details provided by the server. It also includes a try-catch block to handle any other errors that might occur during the process.

This app integrates a custom Stripe subscription API. It includes a backend service set up using FastAPI and is compatible with any price point established through the Stripe API. The backend service creates a Stripe subscription and allows all CORS. It also logs sent requests and subscription statuses. The price ID, customer ID, and payment method are fetched during the request from the user. After adding the Stripe API key, the backend service can be activated by clicking the test button. The required environment secrets for this app are STRIPE_SECRET_KEY.

Introduction to the Stripe Subscription API Template

Welcome to the Stripe Subscription API Template! This template is designed to help you integrate a custom Stripe subscription API into your software applications with ease. The backend service is set up using FastAPI and is compatible with any price point established through the Stripe API. It handles the creation of Stripe subscriptions and allows all CORS, ensuring that you can easily connect it with your front-end applications. Additionally, it logs requests and subscription statuses for better monitoring.

Getting Started

To begin using this template, simply click on "Start with this Template" on the Lazy platform. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy, paste, or delete any code manually.

Initial Setup

Before you can test and use the application, you'll need to set up an environment secret within the Lazy Builder:

  • Go to the Environment Secrets tab within the Lazy Builder.
  • Add a new secret with the key STRIPE_SECRET_KEY.
  • Enter your Stripe secret key as the value for this secret. You can find your Stripe secret key in your Stripe Dashboard under Developers > API keys.

Make sure to save the secret key securely, as it allows your application to communicate with Stripe's API.

Test: Pressing the Test Button

Once you have set up the environment secret, press the "Test" button on the Lazy platform. This will begin the deployment of your application and launch the Lazy CLI. If the application requires any user input, you will be prompted to provide it through the Lazy CLI interface.

Entering Input

After pressing the "Test" button, if the application requires user input, the Lazy CLI will prompt you to provide the necessary information. Follow the instructions in the CLI to enter the required details.

Using the App

After the application has been successfully deployed, Lazy will provide you with a dedicated server link. You can use this link to interact with the API. Additionally, since the code uses FastAPI, Lazy will also provide a link to the FastAPI documentation, which you can use to explore the available endpoints and their specifications.

Integrating the App

To integrate the Stripe Subscription API with your front-end application, you'll need to follow these steps:

  • Include the provided front-end integration script in your HTML page, just before the </body> tag.
  • Replace "PUBLISHABLE STRIPE API KEY" with your actual publishable API key from Stripe.
  • Replace "YOUR SERVER LINK" with the server link provided by Lazy after deployment.
  • Replace "PRICE_ID", "CUSTOMER_ID", and "PAYMENT_METHOD_ID" with the actual IDs you want to use for the transaction.

Here is the sample front-end integration script:

`

` By following these steps, you can seamlessly integrate the Stripe Subscription API into your front-end application and start creating subscriptions with Stripe.

FastAPI endpoint for Text Classification using OpenAI GPT 4

This API will classify incoming text items into categories using the Open AI's GPT 4 model. If the model is unsure about the category of a text item, it will respond with an empty string. The categories are parameters that the API endpoint accepts. The GPT 4 model will classify the items on its own with a prompt like this: "Classify the following item {item} into one of these categories {categories}". There is no maximum number of categories a text item can belong to in the multiple categories classification. The API will use the llm_prompt ability to ask the LLM to classify the item and respond with the category. The API will take the LLM's response as is and will not handle situations where the model identifies multiple categories for a text item in the single category classification. If the model is unsure about the category of a text item in the multiple categories classification, it will respond with an empty string for that item. The API will use Python's concurrent.futures module to parallelize the classification of text items. The API will handle timeouts and exceptions by leaving the items unclassified. The API will parse the LLM's response for the multiple categories classification and match it to the list of categories provided in the API parameters. The API will convert the LLM's response and the categories to lowercase before matching them. The API will split the LLM's response on both ':' and ',' to remove the "Category" word from the response. The temperature of the GPT model is set to a minimal value to make the output more deterministic. The API will return all matching categories for a text item in the multiple categories classification. The API will strip any leading or trailing whitespace from the categories in the LLM's response before matching them to the list of categories provided in the API parameters. The API will accept lists as answers from the LLM. If the LLM responds with a string that's formatted like a list, the API will parse it and match it to the list of categories provided in the API parameters.
