Every app a channel needs, in one store
The marketplace is where each channel gets its tools. Browse 49 apps across 23 categories, see the price before you install, and add or remove apps whenever the work changes. Developers will be able to sell here too, and you can register your interest today.
Three shelves, one catalogue
Inside every channel, the store is split the same way. Sell, Work and Industries. Most channels end up with a few apps from each.
Work
Run the business behind the channel: money, people and operations.
Industries
Apps made for one kind of business, like a clinic, a school or a hotel.
A shop, a till and a catalogue
Sell online and at the counter from one list of products, with stock that keeps up.
Commerce apps

All 23 categories
Some categories hold a single app built for one kind of business. Each link opens that category with every app in it.
From the store to a working tab in a minute
Apps belong to a channel, not to the whole business. That keeps a clinic's tools out of a shop's way, and keeps each channel's bill honest.
Open the channel
Every channel has an Apps tab. It lists what is installed, what it costs each month and a button to add more.
Find the app in the store
Browse the shelves, open a category or search by what you need, like bookings or payroll. Each app shows its features and its monthly price.
Confirm the price
Before anything happens you see the cost: the monthly price per channel, before VAT or sales tax, billed monthly after use. Free apps say so.
Start using it
The app's tabs appear in the channel straight away. There is no separate sign-in and no second account to manage.
Decide who can use it
Each app has its own settings. Choose which roles on the channel can use it: Owner always can, and Admin, Member and Viewer can be switched on or off.
Install CRM?
Free. New tabs appear in this channel right away.
Install, pause or remove
You are never locked into an app. Here is exactly what happens in each case.
| You | The app's tabs | Your data | Billing |
|---|---|---|---|
| Install | Appear in the channel straight away | Starts empty. You can import a CSV from the app's settings | The monthly price per channel, before tax, billed monthly after use |
| Turn it off | Hidden from everyone on the channel | Kept exactly as it was | The app is still installed. Uninstall it if you want the charge to stop |
| Uninstall | Disappear at once | Kept for 30 days, so you can come back or export it | Stops at the end of the billing period |
Each app's settings also has an Export as CSV button, so your records are always yours to take.
Apps follow the brand, not the org chart
In Intersink, a business holds channels, and a channel holds apps. A channel is one brand, branch, shop or website you run.
That order matters in the store. A salon chain might run three channels. Two need bookings and a till. The third sells hair care online and needs a store and delivery instead. Each installs what it uses and nothing more.
Roles work the same way. Someone can be an admin on one channel and a viewer on another, and each app lets you choose which roles can open it. Every business also keeps an audit log, so owners can look back at what the team changed.
When a channel outgrows an app, remove it. When it needs a new one, add it. The bill for next month follows what you actually used.
Build an app for every channel on the platform
We plan to open the marketplace to outside developers. It is not open yet, and we would rather say so plainly than take listings we cannot support. Here is what you can do today, and how we expect publishing to work.
- Public API and webhooksAvailable now
- Test keys and test modeAvailable now
- Developer registration and listingsPlanned
- Review by a person before listingPlanned
What you can build on today
Every channel already has an API and webhooks. The API reference is public. It covers authentication with secret keys sent as a Bearer token, JSON in and JSON out over HTTPS, cursor pagination, rate limits and dated versions.
Channel admins create keys under API and webhooks. A test key never moves real money, and a channel's test mode keeps practice orders, emails and payments away from real customers. Keys can be rotated or revoked at any time.
Webhooks are signed, so you can check each event came from us. Failed deliveries are retried with backoff for 24 hours, and events can be replayed. That is the same foundation marketplace apps will use.
# List the newest leads on a channel, with a test key
GET /v1/channels/{channel}/leads?limit=1
Authorization: Bearer sk_test_…
# Every POST that creates or charges takes
# an idempotency key, so a retry never runs twice
POST /v1/products
Idempotency-Key: <your unique id>How we expect publishing to work
Register as a developer
With your own User ID, the same free account everyone uses. You would tell us who you are and what you want to build.
Build against test mode
Use test keys and a test channel until everything behaves. Nothing touches real customers or real money.
Describe the app honestly
A listing with a plain description, the features it really has, its price per channel per month, and exactly what data it reads and writes.
Review by a person
We would install it, try it on a test channel and check it against the standards below before it appears in any store.
Listed in every channel's store
Once approved, channel admins could find it on the right shelf and install it the same way as any other app.
What review would check
These follow the rules our own apps already keep.
- Permissions stated up front. Every connection lists what it can see and do before anyone connects it.
- Roles respected. The app works inside the channel's roles and never gives someone more access than their role allows.
- The price shown is the price. Per channel per month, before VAT or sales tax, with no surprises after install.
- Safe retries. Create and charge calls use idempotency keys, and webhook handlers cope with the same event arriving twice.
- Data you can take away. Uninstalling leaves a business able to export what the app held.
- No passwords, ever. An app must never ask for a password or a one-time code.
What you would need
Likely requirements. We will confirm them when the programme opens.
- A User ID, and a business in your name or your company's
- An app that works end to end on a test channel
- A clear listing: what it does, who it is for, its price
- A support contact that real customers can reach
- A privacy notice covering the data your app handles
- Agreement to the developer terms, once we publish them
Tell me when the developer programme opens
One email when there is something to sign up for. No newsletter. In the meantime, the API reference is open to read.
