API Development and Integration
Connect your website, CRM, accounting, payments and apps so information moves between them without retyping.
How we approach
API development and integration.
Most businesses run several tools that do not know about each other, so people retype the same details into each one. We connect them. An order on your website becomes an invoice, a new lead lands in your CRM, stock matches between the shop and the warehouse. We also build the interfaces other systems use to talk to yours, with clear documentation and sensible access limits.

The results
we work towards.
Fewer retyping errors and faster order handling
Systems that can grow without being rewired each time
These are intended outcomes. Priorities and measures are agreed for each project.
Read before
you decide.
SaaS billing and subscription basics
How recurring billing works: plans, trials, upgrades, failed payments and invoices. What to decide before you build and what a payment provider handles.
API security basics for business systems
An API is a door into your system. Authentication, limited access, input checks, rate limits and logging keep that door safe.
API versioning explained: how to change an API without breaking customers
When other systems depend on your API, changes can break them. Versioning lets you improve safely: how it works and how to announce changes.
Can you connect any system to any other?
Only when the systems offer a way to connect. We check what each one supports before we promise anything, then confirm in writing what is possible and what is not.
Is connecting systems safe?
It can be, when access is limited to what is needed, secret keys are kept out of sight and activity is logged. We build those controls in from the start.
Do you document what you build?
Yes. You receive plain documentation of what connects to what, so another supplier can look after it if you ever change.
Do you work with clients outside South Africa?
Yes. Real Tech Solutions is based in South Africa, with clients in Johannesburg, Pretoria, Centurion, Cape Town and Limpopo, and works with clients in other countries remotely. Meetings, reviews and handover happen online, and we agree working hours and communication channels at the start of the project.
