# My Pages

This guide describes how to use the API to provide tenants with information about their objects, contracts, invoices, payments, errands, and related data (a “My Pages” experience).

## Sections

- [Activation level](/guides/cases/my-pages/activation-level) — Per real estate or per organization.
- [Access](/guides/cases/my-pages/access) — Entities for structures, contracts, users, invoices, and errands.
- [Implementation example](/guides/cases/my-pages/implementation-example) — Data fetching examples by area.


## Entity relationships

Start from [accounts.tenant](/apis/accounts) (or [accounts.subtenant](/apis/accounts)) and traverse to spaces, contracts, invoices, payments, errands, and notifications.
