Why CoSuite

Build your product. We handle the rest.

Businesses already sign up, pay and sign in on CoSuite. Your module joins that flow instead of rebuilding it.

cosuite.io

A ready sales channel

Your modules appear in the CoSuite catalog, the signup flow, the subscription screen and on cosuite.io, right where businesses choose what they need.

Your data stays yours

Business data stays in your app. CoSuite keeps only an access log, never request or response bodies.

2FA

Secure by design

Every call is HMAC-signed with replay protection, sign-in uses ES256 tokens, and two-factor login is mandatory for partners.

Connect v1

One standard, no rewrite

Keep your UI and your database. Add a few signed endpoints under /api/cosuite/v1 and you are connected.

For your customers

Your API, through CoSuite.

Customers can call your module's API through CoSuite's API gateway with their own CoSuite key and scopes, and subscribe to your module's webhooks. The only extra work on your side: describe your API in OpenAPI 3.1.

CustomerCoSuite key + scopes

api.cosuite.ioAPI gateway

Your moduleOpenAPI 3.1

Webhooks back to the customer

Their own key

Customers use the API key they already have in CoSuite. No separate credentials to issue.

Scoped access

Each key carries scopes, so customers reach only what they are allowed to.

Webhooks

Customers subscribe to your module's events from CoSuite.

No extra integration

Describe your API once in OpenAPI 3.1; there is nothing else to build.

Where modules fit

Fill the gaps businesses feel every day

Third-party modules shine where a sector needs depth CoSuite doesn't offer yet. For example:

Treatment plans for dental clinics

Shipping and cargo integrations

Accounting integrations

Industry-specific tools

Clear rules

Fair for partners, clear for customers

The catalog stays easy to trust, for businesses and for you.

Gaps first: work CoSuite doesn't do yet.
Modules that overlap a CoSuite feature can apply too; they are listed after review and approval.
The signup flow always recommends CoSuite's own module, and one job is never handled by two modules in the same business.
At launch, only registered companies can apply.
