REST APIs
Resource-oriented JSON with clear status codes.
API & backend
API and backend development that other systems can trust
Frontends are temporary. Data models and APIs last. ZEH Technologies builds REST APIs, third-party integrations, database architecture, authentication, webhooks, backend systems, payment APIs, CRM integrations, automation APIs and mobile app APIs.
A good API has versioning, validation, pagination, error shapes, and authentication that matches the client. A good backend has migrations, backups and jobs that can be retried.
Auth
Tokens, sessions, API keys—chosen to fit the client.
Webhooks
Outbound events other tools can subscribe to.
Third-party APIs
Payments, CRM, email, shipping, AI providers.
SQL databases
Schemas that match the domain.
Mobile backends
The same API serving app and web.
