The language in which almost all modern software talks to each other.
A REST API is the most common way in which software systems exchange data over the Internet. It works with fixed addresses and standard commands: retrieve, create, change and delete. Because almost every modern package follows the same pattern, connections between systems can be built predictably.
IN COMMON LANGUAGE
Why this matters when choosing software
You don't need to know how it works, just whether your package has it. A supplier with a documented REST API can be linked; a supplier without it is often not, or only at high costs.
Therefore, ask for the API documentation for every software choice. If it is public and up to date, that is a good sign. If it doesn't exist, you're stuck with what the package itself can do.
WHY IT MATTERS
What you pay attention to
Documentation is the most important indicator. Public, up-to-date documentation means that the supplier takes links seriously.
Also pay attention to limits: how many requests can you make per minute. For large amounts of data, this determines whether a link is practically workable.
- Public documentation — the clearest sign that linking is possible.
- Access to a test environment — building without testing is gambling.
- Request limits — determine whether large volumes are workable.
- Webhooks available — saves constant inquiries.
- Stable versions — so that your coupling doesn't just break.
FREQUENTLY ASKED QUESTIONS
More about a REST API
Do I need to understand this as an entrepreneur?
No. It is useful to ask whether there is a documented API for each software choice. That one answer determines whether you can connect that package later or whether you are stuck.
What if my package doesn't have an API?
Then usually only file exchange remains: periodic export and import. That works, but is slower and breaks more often. We find out in advance what is possible.
Does API access cost extra from my supplier?
Sometimes. Some suppliers charge for it or require a more expensive subscription. Ask before you have a connection built.
