Got Questions?

Frequently Asked Questions

Straight answers about API Integration.

An API integration connects to an existing external service, while a custom-built feature is developed entirely in-house. Integration is faster and more cost-effective for standard functionality.

Timelines vary based on complexity — from a few days for simple integrations to several weeks for complex multi-system setups.

REST APIs use fixed endpoints that return predefined data structures, while GraphQL APIs allow clients to request exactly the data they need through flexible queries, often reducing unnecessary data transfer.

Data security is managed through encrypted connections (HTTPS), secure authentication methods like OAuth 2.0, and careful handling of sensitive data such as payment information, in line with relevant compliance standards.

Integrations are designed with monitoring in place to detect provider-side changes. When an API is updated or deprecated, the integration is modified accordingly to maintain functionality without disrupting the application.

Yes. New integrations can typically be added to existing applications through modular development, minimizing disruption to existing functionality.

Yes. We offer ongoing monitoring, maintenance, and updates to ensure integrations continue functioning reliably as third-party APIs evolve over time.
