APIs and system integration
so your tools work together.
Most businesses run several tools that do not know about each other. These guides explain how systems connect: what an API is, how to keep one secure, how webhooks differ from polling, and what to check before connecting accounting software or a payment gateway.
Our APIs and integration
services.
Each service has its own page with what is included and common questions.
5 guides on
APIs and integration.
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.
Webhooks or polling: two ways for systems to stay in sync
Polling asks again and again whether anything changed. Webhooks tell you when something does. How each works and which to choose for your integration.
Connecting accounting software to your shop, CRM or system
Invoices and payments often get typed twice. What can be connected to accounting software, what to check first and how to avoid duplicate records.
What good API documentation looks like
Documentation decides whether other developers can use your API. What it should include: examples, errors, limits and a clear way to get started.
Can any two systems be connected?
Only when they offer a way to connect. Check what each one supports before you plan anything, and confirm in writing what is possible.
How do I keep an integration secure?
Give each connection only the access it needs, keep keys secret, check what comes in and keep logs. Our API security guide has the basics.
