Hosting Terms
What is API?
API in plain English — the meaning, the comparison, and why it matters to anybody running a website.
Straight answer first
An API is an agreed way for one piece of software to talk to another — the fixed contract two services use to swap data and issue commands without a human in the middle.
The sections below open it up properly — how it works, why a site owner should care, and a concrete example of it doing its job.

To read, naturally
Web APIs speak HTTP. You send a request to an endpoint and get structured data back, almost always JSON. Your site sits on both sides of that: it calls out to payment gateways, mapping services and data feeds, and it can serve data itself, as WordPress does through its REST API.
Keys and tokens are what prove who is calling. They authorise actions in your name, which makes them exactly as sensitive as a password and deserving of the same handling.
The everyday comparison
A serving hatch with a printed order pad. You pass a request through the window in the agreed format and the dish comes back. You never need to walk into the kitchen or learn how the sauce was made.
Keep that picture in mind and most of the documentation you will ever read on the subject stops being mysterious.
What it means for your own site
A modern site is a bundle of APIs tied together — checkout, email, analytics, stock feeds, shipping. Once you understand the pattern, both the integrations and the ways they fail stop being mysterious.
That is the test for any technical term, incidentally — not 'do I understand it fully' but 'do I know when it is the answer to my problem'. For this one, you now do.
One concrete example
Someone clicks 'ship it' in a shop and the courier's API is called. A label comes back, a tracking number is stored, the order updates. Three systems finish a conversation in a couple of seconds.
Perfectly ordinary once you have seen it, which is rather the point: most hosting concepts are simple machinery wearing an intimidating name.
Where you will meet it on our platform
You will meet it in the control panel and occasionally in a support conversation, usually already set the right way. If this term made sense, the natural next reads are Webhook, PHP, WordPress and Encryption.
Bring an existing site and we shift it across at no charge — usually inside 24 hours, with nothing going dark while we work.
A glossary written by the people on the counter
We treat unexplained jargon as a service failure. This glossary is the support desk's accumulated translations, published where a search engine can hand them out for us.
Real people answer the counter at any hour, including the awkward questions other hosts wave off as out of scope.

Why Hosting Seller
On every plan, as standard
Plain English first
Every term defined for people who run sites, not for other sysadmins — jargon translated rather than restated.
Pictures that stick
Each concept gets a comparison you will still remember at the moment you actually need it.
The next reads, mapped
Read on into Webhook and PHP — terms rarely stand alone, so the neighbours are linked.
Honest about what to skip
Most terms are recognise-level rather than operate-level, and the glossary says which is which.
Linked, never siloed
Related terms cross-reference each other, so one lookup grows into a working understanding.
One term, fully landed
API defined, pictured by comparison and placed in your own control panel — recognise-level in a single read.
First Steps
From choosing to live
- 1
Find it in your own account
The quickest way to learn a hosting term is to find it in your own panel; five minutes of looking beats an hour of reading about it.
- 2
Check what the defaults are
Our platform ships sensible defaults for this — check rather than assume, and you will know your setup instead of hoping about it.

Across the Counter
The questions we get asked most
Where do APIs actually touch my hosting?
In two places. Your code makes outbound calls, which need network access and sensible timeouts so a slow third party cannot stall your pages. And other systems call your endpoints, which need HTTPS and authentication. Both are ordinary web traffic wearing a structured format.
What is an API key and how carefully should I treat it?
It is a credential that lets something act as you. Treat it like a password: keep it out of version control, give it the narrowest permissions the job allows, and replace it the moment it might have leaked. Most 'our integration got hacked' stories are really a key that ended up somewhere public.
Can I test changes somewhere safe first?
Yes — plans with staging let you clone the live site, work on the copy, then push it across when you are satisfied. It is the difference between hoping an update behaves and knowing that it does before any customer meets it.
Can I set the PHP version myself?
Yes — PHP versions are chosen per site from the control panel, so an old application and a current one can sit side by side on the same account. Extensions and per-site settings live in the same screen, and none of it needs a support ticket.
Do you shift an existing site across at no charge?
We do. Open a ticket with the login details for your current host and the whole lot comes over: files, databases, mailboxes and configuration. You check the copy before DNS changes hands, and the old site keeps serving customers until the new one takes the traffic, so nobody ever sees a gap.
Does hosting come with mailboxes?
It does — mailboxes on your own domain ship with every hosting plan, with webmail, IMAP, POP and SMTP access and spam filtering fitted as standard. There is also standalone email hosting for domains whose website lives somewhere else entirely.
What does round-the-clock support actually stretch to?
People at the counter at every hour, and a scope that takes in the practical work: mailbox setup, DNS records, WordPress trouble, restores. Not 'the server responds, ticket closed'. Ask us something hard before you order — the reply is a fair sample of what you would get afterwards.

Do the launch properly this time.
Quick NVMe hosting, SSL and the move in included, and real people on the counter at any hour — on a price that doesn't shift.
