Frequently Asked Questions

What third-party APIs can you integrate?

We integrate payment gateways (Stripe, PayPal), CRM systems (Salesforce, HubSpot), marketing tools (Mailchimp, SendGrid), social media APIs, shipping services, and virtually any API with documentation.

How long does API integration take?

API integration typically takes 1-4 weeks depending on API complexity, authentication requirements, data transformation needs, and number of endpoints being integrated.

What if the third-party API changes?

We implement error handling and monitoring to detect API changes. We also provide maintenance packages to handle API updates, version migrations, and ensure continued functionality.

Can you integrate multiple APIs together?

Yes, we create custom middleware that connects multiple APIs, transforms data between systems, handles authentication for each service, and orchestrates complex multi-API workflows.

How do you handle API rate limits?

We implement intelligent rate limit management, request queuing, caching strategies, batch processing, and fallback mechanisms to work within API limits while maintaining functionality.

Will the API integration be secure?

Yes, we securely store API credentials, use encrypted connections, implement proper error handling that doesn't expose sensitive data, and follow each API's security best practices.

How much does API integration cost?

API integration ranges from $1,000 to $8,000 depending on API complexity, number of endpoints, data transformation requirements, and authentication method. Simple integrations start at $1,000.
