API Development: Connecting Your Business Systems

Modern businesses use dozens of software tools that need to share data. APIs are the bridges that connect these tools, allowing information to flow automatically between your website, CRM, accounting software, and other systems.

Common API Use Cases

• Payment processing: Connect your website to Stripe, PayPal, or Square for secure transactions
• CRM integration: Send website leads directly to HubSpot, Salesforce, or your CRM
• Shipping calculation: Real-time rates from USPS, UPS, FedEx on your checkout page
• Inventory sync: Keep product availability accurate across website, marketplace, and POS
• Email marketing: Add customers to email lists, trigger sequences based on website actions
• Accounting: Sync invoices, payments, and expenses with QuickBooks or Xero

REST vs GraphQL

Two main API architectures:

• REST: The standard approach. Simple, well-documented, works with any programming language. Best for most business integrations.
• GraphQL: More flexible data querying. Best for complex applications that need specific data subsets. Overkill for most small business needs.

API Security

APIs handle sensitive data and must be secured:

• Authentication (API keys, OAuth tokens)
• Rate limiting (prevent abuse)
• Input validation (prevent injection attacks)
• HTTPS only (encrypted transmission)
• Logging and monitoring (detect suspicious activity)
