Most modern products are a set of systems talking to each other. A clear API is how a website, app, warehouse tool and payment provider stay in sync without copy-paste chaos.
WEBCETRA designs REST APIs, connects third-party services and implements authentication and data access with explicit error handling.
Who this is for
- Teams whose website, app and admin tools need a shared backend
- Stores that must connect payments, ERP or shipping platforms
- Companies replacing brittle Zapier-only plumbing with something they own
What we include
REST APIs and custom APIs
Resource-oriented HTTP APIs with consistent errors, pagination and versioning where needed.
Third-party and payment integrations
Checkout, invoices, identity providers and other vendors — implemented against their current docs, not blog samples from 2018.
E-commerce APIs
Catalogue, order and inventory interfaces between storefronts and operational systems.
Database integrations and authentication
Access layers that do not expose the database to the internet, plus session or token auth appropriate to the client.
How delivery works
Contract first
Endpoints, payloads and auth are agreed before large amounts of UI are built on sand.
Implement and test
Happy paths, failure paths and idempotency for payments and order creation.
Document
Enough documentation for the next developer — including yours or ours.
What you should expect
- One backend multiple clients can share
- Fewer fragile point-to-point scripts
- Auth and data access that can be reasoned about
