# Class Guides

Step-by-step guides for building against Class. Each guide covers registration,
authentication, and the full request and response flow, with the API reference
alongside it.

All three integrations use the same two environments: the Partner Integration
Environment for development and testing, and Production once you're live.

## [Practice Management](/products/class/guides/practice-management/practice-management)

Keep fund and member records aligned between Class and your practice management
system. Read and update fund details such as name, ABN, TFN and reporting
preferences, and member details including contact information and beneficiaries.

This is a standard integration — your system calls Class.

## [Actuarial Certificate Provider](/products/class/guides/actuarial-certificate-provider/overview)

For actuarial certificate providers. Class initiates a certificate request and
sends it to your system; you create and update the request status as work
progresses, then upload the signed certificate document back to Class.

This is a callback API, so you'll need to be a registered Actuarial Certificate
Provider before you can use it. The guide covers registration, both directions of
the exchange, and the full workflow.

## [One Click Audit](/products/class/guides/one-click-audit/overview)

For external audit providers. Class initiates an audit request; you return status
updates, progress messages, audit documents, completion details, and error
messages against that request.

This is also a callback API and requires registration with Class first. The guide
covers the request Class sends you, the status values you can set, and what each
one expects in the payload.
