Hosting Glossary
What is Webhook?
Webhook in plain English — the definition, the analogy, and why it matters to anyone who runs a website.
The short answer
A webhook is an API call in reverse — a service pushes a notification to your URL the moment something happens, instead of you polling to ask.
The sections below unpack it properly — how it works, why a site owner should care, and a concrete example of it in the wild.

To read, obviously
You register an endpoint URL; the service POSTs event data to it (payment completed, form submitted, repo pushed). Event-driven and immediate, versus the wasteful rhythm of asking repeatedly.
Reliability etiquette matters: endpoints should verify signatures (anyone can POST to a URL) and respond quickly, with services typically retrying failed deliveries.
A picture that makes Webhook stick
A doorbell instead of checking the doorstep hourly — the caller announces arrival the moment it happens, and you verify it's really the courier before opening.
Analogies simplify, of course — but this one holds up well enough to reason with, and reasoning is the point of a glossary.
Why you should care
Webhooks stitch modern stacks together — payment confirmations, deploy triggers and automation flows ride them; knowing the pattern turns integration docs from magic into plumbing.
That's the test for every technical term, incidentally — not 'do I understand it fully' but 'do I know when it's the answer to my problem'. For this one, now you do.
A concrete example
Stripe POSTs a payment-succeeded event to a store's webhook endpoint — the order flips to paid and the receipt sends, seconds after the card cleared, no polling anywhere.
Multiply that example across every site on the internet and you have the concept's entire job description.
How this shows up in your hosting
You'll meet it in the control panel and occasionally in a support conversation — usually already configured the right way. If this term made sense, the natural next reads are API, Git, WooCommerce and Cron Job.
Every plan includes free SSL that renews itself, so the padlock is never your job.
A glossary from people who answer tickets
Every confusing term in hosting eventually becomes a support ticket — so we defined the hundred most common ones properly, once, in the plain English we'd use on the phone.
Renewal prices match signup prices, so the year-two invoice is the most boring email you'll get from us.

Why HostingAlly
Every plan includes this, whatever you pay
The next reads, mapped
This entry connects to API and Git — concepts travel in packs, and the pack is linked.
Plain English first
Every term defined for site owners, not for other sysadmins — jargon translated, not restated.
Analogies that stick
Each concept gets a picture you'll remember at the moment you actually need it.
Linked, not siloed
Related terms cross-reference, so one lookup becomes a working understanding.
The practical stakes named
Not just what it is — when it's the answer to a problem you're having.
Grounded in a real platform
Examples reference the hosting you'd actually use, not abstract diagrams.
Getting Started
How to get going
- 1
Spot it in your own setup
Open your control panel and find where this concept lives — seeing it attached to your own site is what converts definition into understanding.

FAQ
Your questions, answered
Webhook or cron — when does each fit?
Webhooks for event-driven immediacy (something happened, react now); cron for schedule-driven work (every night, do this). Mature systems use both — events for the moments, schedules for the sweeps.
Are webhooks secure?
Secured ones are — HTTPS endpoints verifying the service's signature on each delivery. An unverified endpoint accepts forgeries; the signature check is the difference between a doorbell and an open door.
How do I pay, and is billing recurring?
Plans are billed by credit or debit card through our secure checkout, with the renewal price matching the signup price. You can see every invoice in the client area, and cancelling auto-renewal is a setting, not a phone call.
Is SSL really included at no cost?
On every plan, with no exceptions — certificates are issued automatically when your domain points to us and renew themselves before expiry. The encryption is identical to paid DV certificates; paid tiers exist only for wildcard convenience or organisation-level validation.
Can I host more than one website on a plan?
On the Pro tier and above, yes — multiple sites with their own domains, email and SSL under one account. If the extra sites belong to clients rather than you, reseller hosting gives each one proper isolation instead.
How do I read my email away from my desk?
Webmail works from any browser, and every mailbox also supports IMAP, POP and SMTP — so your phone's mail app, desktop client and webmail all see the same messages.
Do you support staging sites?
Yes — plans with staging let you clone the live site, test changes safely, and push to production when ready. It's the difference between 'I hope this update works' and knowing it does.

Planning to switch hosts? Grab the checklist here.
The steps that keep a site migration dull rather than dramatic: what to back up first, how to shift email across without losing a single message, when to touch DNS, and the two mistakes behind nearly every hour of downtime we come across.
Start with hosting that has your back.
From your first site to a fleet of servers, the upgrade path is an account change, not a migration.
