400: Bad Request (missing parameters, invalid data)
401: Unauthorized (invalid or missing API key)
403: Forbidden (insufficient permissions)
404: Not Found (product, pricing plan, or subscription not found)

Rate Limiting

API calls are subject to rate limiting based on your subscription plan
Rate limits are enforced per API key
Exceeding limits will result in 429 (Too Many Requests) responses

Best Practices

1. Always Check Current Subscription

Before making changes, retrieve the current subscription to understand the current state.

2. Use Dry Run for Testing

Set isDryRun: true in the request body to simulate operations without making actual changes.

3. Handle Errors Gracefully

Implement proper error handling for all API responses, especially for network failures.

4. Monitor Subscription Changes

Track subscription changes in your application to provide users with real-time updates.

Example Integration

class SubscriptionManager {
  constructor(apiKey, baseUrl = 'https://api.market') {
    this.apiKey = apiKey;
    this.baseUrl = baseUrl;
  }

  async getProductDetails(workspaceSlug, productSlug) {
    const response = await fetch(
      `${this.baseUrl}/api/v1/product/${workspaceSlug}/${productSlug}`,
      {
        headers: {
          'x-api-market-key': this.apiKey,
          'accept': 'application/json'
        }
      }
    );
    return response.json();
  }

  async getCurrentSubscription(workspaceSlug, productSlug) {
    const response = await fetch(
      `${this.baseUrl}/api/v1/subscription/${workspaceSlug}/${productSlug}`,
      {
        headers: {
          'x-api-market-key': this.apiKey,
          'accept': 'application/json'
        }
      }
    );
    return response.json();
  }

  async createSubscription(workspaceSlug, productSlug, pricingPlanId, options = {}) {
    const response = await fetch(
      `${this.baseUrl}/api/v1/subscription/${workspaceSlug}/${productSlug}/${pricingPlanId}`,
      {
        method: 'POST',
        headers: {
          'x-api-market-key': this.apiKey,
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          isDryRun: options.dryRun || false,
          additionalData: options.additionalData || ''
        })
      }
    );
    return response.json();
  }

  async cancelSubscription(workspaceSlug, productSlug, options = {}) {
    const response = await fetch(
      `${this.baseUrl}/api/v1/subscription/${workspaceSlug}/${productSlug}`,
      {
        method: 'DELETE',
        headers: {
          'x-api-market-key': this.apiKey,
          'Content-Type': 'application/json'
        },
        body: JSON.stringify({
          cancelImmediately: options.immediate || false,
          reason: options.reason || ''
        })
      }
    );
    return response.json();
  }
}

// Usage
const manager = new SubscriptionManager('your-api-key');

// Get product details
const product = await manager.getProductDetails('magicapi', 'upscaler');

// Check current subscription
const subscription = await manager.getCurrentSubscription('magicapi', 'upscaler');

// Create new subscription
const newSubscription = await manager.createSubscription(
  'magicapi', 
  'upscaler', 
  'cltivivul000clc0crn8momz5',
  { dryRun: false }
);

// Cancel subscription
const cancelResult = await manager.cancelSubscription(
  'magicapi', 
  'upscaler',
  { reason: 'No longer needed', immediate: false }
);
