Everything you want to know explained clearly
Both. REST fits most public and partner-facing APIs, and GraphQL fits applications that need flexible, efficient access to related data. We also build webhook and event-driven integrations using message queues and Kafka. We choose the approach based on who consumes the API and how, then document every endpoint.
Yes. We build integration layers that let new applications read from and write to older systems, including ERPs and on-premise databases, without rewriting the legacy system or disrupting daily operations. It is often the first step in a longer modernization plan.
Payment gateways, CRMs like Salesforce, ERPs, marketing automation, support platforms, and most services that expose an API or webhooks. When a vendor's API is poorly documented or rate-limited, we design around it with queuing, retries, and monitoring.
Error handling and monitoring are designed before development starts. Our integrations include retries, handling for messages that can't be processed, data validation at each boundary, and alerts when something breaks, so your team hears about a failure before a customer or a finance report does.
Every API gets authentication and authorization, centralized rate limiting and access control through an API gateway, and encryption in transit. For financial and healthcare clients we design around PCI-DSS and HIPAA requirements, and First Factory is SOC 2 Type II compliant itself.
