## Subscription Tier Manager Technical Documentation

### 1. Subscription Plans
The core of our system, this module allows businesses to define multiple subscription tiers with unique names, prices, durations (monthly or annual), and features. Each tier can be tailored to offer varying levels of access, such as basic vs. premium services, enabling a flexible pricing strategy.

### 2. Flexible Subscription Types
Supports both monthly and annual subscriptions, providing flexibility for businesses to cater to different customer preferences and market strategies, enhancing customer acquisition and retention through varied subscription options.

### 3. Pricing Rules
Configurable conditions that apply discounts or tier upgrades based on user behavior or purchase history. For example, bulk purchases can trigger a discount, or usage patterns may automatically elevate the user to a higher tier, enhancing customer value.

### 4. Trial Periods
Manages free trial periods (e.g., 7 or 14 days) to attract new customers. The module integrates with upselling features post-trial, converting trials into paid subscriptions and offering options for different tiers upon purchase.

### 5. Renewal Management
Automates subscription renewals by processing payments on behalf of the business, ensuring seamless operations without manual intervention. This feature minimizes customer churn by handling billing efficiently.

### 6. Usage Limits
Sets resource or service limits per tier to control access levels and ensure fair usage. Exceeding these limits can trigger notifications or automatic upgrades, guiding users to suitable plans.

### 7. Discounts and Promotions
Applies promotional offers such as percentage discounts or fixed amounts on subscriptions. Configurable for scenarios like first-time purchases or holidays, this feature aids in attracting and retaining customers through flexible pricing strategies.

### 8. Tier Upgrades/Downgrades
Enables dynamic changes to subscription tiers during the billing cycle. Customers can seamlessly move up for more features or down for cost savings, enhancing their experience with flexible options.

### 9. API Integration
Provides APIs for integration with third-party systems, allowing businesses to automate subscription management within their existing tech stack. Offers endpoints for operations like creating subscriptions, facilitating seamless integration and efficient workflow management.

### 10. Audit Logs and Reporting
Maintains comprehensive logs of all subscription-related activities, crucial for monitoring user actions, debugging issues, and ensuring compliance with regulations. These reports provide detailed insights into billing and usage trends, aiding in strategic decision-making.

#### 1. FastAPI Endpoint

This endpoint retrieves all available subscription tiers from the system.

```python
from fastapi import APIRouter, Depends
from typing import List
from pydantic import BaseModel

router = APIRouter(prefix="/subscription-tiers")

class SubscriptionTier(BaseModel):
    id: str
    name: str
    price: float
    duration: str  # "monthly" or "annual"
    features: List[str]
    is_active: bool

# Example response model
SubscriptionResponse = dict[str, any]

@router.get("/", response_model=List[SubscriptionTier])
async def get_subscription_tiers():
    """
    Retrieve all available subscription tiers.
    """
    # In a real implementation, this would query a database
    tiers = [
        SubscriptionTier(
            id="tier_1",
            name="Basic Tier",
            price=9.99,
            duration="monthly",
            features=["Basic features", "Limited usage"],
            is_active=True
        ),
        SubscriptionTier(
            id="tier_2",
            name="Pro Tier",
            price=29.99,
            duration="monthly",
            features=["Advanced features", "Unlimited usage", "Priority support"],
            is_active=True
        )
    ]
    return tiers

2. React UI Snippet

This component fetches and displays subscription tiers using the API endpoint.

import { useState, useEffect } from 'react';

const SubscriptionTiersList = () => {
    const [tiers, setTiers] = useState<SubscriptionTier[]>([]);
    const [loading, setLoading] = useState(true);
    const [error, setError] = useState<string | null>(null);

    interface SubscriptionTier {
        id: string;
        name: string;
        price: number;
        duration: string;
        features: string[];
        is_active: boolean;
    }

    useEffect(() => {
        fetch('/api/subscription-tiers/')
            .then(response => response.json())
            .then(data => {
                setTiers(data);
                setLoading(false);
            })
            .catch(err => {
                setError('Failed to fetch subscription tiers');
                setLoading(false);
            });
    }, []);

    if (loading) return <div>Loading...</div>;
    if (error) return <div>{error}</div>;

    return (
        <div>
            <h1>Available Subscription Tiers</h1>
            <ul>
                {tiers.map(tier => (
                    <li key={tier.id} className="subscription-tier">
                        <h3>{tier.name}</h3>
                        <p>Price: ${tier.price.toFixed(2)}</p>
                        <p>Duration: {tier.duration}</p>
                        <div>Features:</div>
                        <ul>
                            {tier.features.map(feature => (
                                <li key={feature}>{feature}</li>
                            ))}
                        </ul>
                    </li>
                ))}
            </ul>
        </div>
    );
};

export default SubscriptionTiersList;

3. Pydantic Data Schema

This defines the structure of a subscription tier.

from pydantic import BaseModel

class SubscriptionTier(BaseModel):
    id: str
    name: str
    price: float
    duration: str  # "monthly" or "annual"
    features: List[str]
    is_active: bool
    
# Example usage:
subscription_tier = SubscriptionTier(
    id="tier_1",
    name="Basic Tier",
    price=9.99,
    duration="monthly",
    features=["Basic features", "Limited usage"],
    is_active=True
