API Integration & Development

Connecting the Digital Ecosystem

Modern digital businesses rely on dozens of different platforms to operate. From CRMs and marketing software to payment gateways and inventory databases, software exists in silos. Nexus Softworks engineers robust API integrations that weave your disparate systems into a unified, automated ecosystem.

Whether you need to connect your frontend application to a third-party service, or you require us to build a secure, highly-performant REST or GraphQL API from scratch, our backend engineers ensure your data flows flawlessly.

We specialize in highly secure data transmission protocols and microservice architectures:

  • Custom API Engineering: Architecting RESTful and GraphQL APIs that act as the backbone for your web and mobile applications.
  • Payment & Financial Integrations: Secure, encrypted integration with Stripe, Plaid, PayPal, and open banking protocols.
  • CRM & Marketing Sync: Bi-directional data synchronization with Salesforce, HubSpot, Mailchimp, and other enterprise tools.
