Frequently Asked Questions Common Questions About API & Integration Services
Find answers to the most common questions about integration and API development.
General Questions
API development creates the connectors that allow different software systems to communicate. APIs enable your applications to share data, trigger actions, and work together seamlessly. We build custom REST APIs, GraphQL APIs, and webhooks that connect your systems.
Simple APIs or single integrations typically range from $10,000-$30,000. Medium-complexity projects range from $30,000-$75,000. Complex enterprise integration platforms can range from $75,000-$200,000+.
We integrate virtually any system with an API. Common integrations include CRMs (Salesforce, HubSpot), ERPs (NetSuite, SAP), accounting (QuickBooks, Xero), e-commerce (Shopify), payment processors, and hundreds of SaaS applications.
Simple integrations: 2-4 weeks. Multi-system integrations: 1-3 months. Complex enterprise platforms: 3-6+ months. We deliver working integrations incrementally.
Technical Questions
We implement both. Real-time (APIs/webhooks) provides instant sync for customer-facing apps. Batch handles large data volumes on schedules. Many solutions use hybrid approaches.
We build transformation layers that map, convert, and validate data between systems with different formats. This includes format conversion, field mapping, enrichment, and validation rules.
Security is built in: authentication (OAuth, API keys, JWT), authorization, rate limiting, input validation, TLS encryption, and audit logging. We follow OWASP API Security guidelines.
Yes, we offer integration maintenance packages including monitoring, error resolution, adapting to API changes, and adding new integrations as needs grow.
