A family dashboard is a useful test of any financial API because the data model has to support more than one person, more than one account type, and more than one definition of "ours."
The Tablewealth API is designed around scoped access to financial data so you can build custom interfaces without pushing every family workflow into the default dashboard.
Model the household first
Start with the questions your household actually asks. You might need shared checking, separate credit cards, joint investments, individual retirement accounts, and a rollup for long-term planning. The dashboard should make those boundaries visible instead of flattening everything into one total.
Pull only what the screen needs
A good API integration should request the smallest useful slice of data for the current view. A top-level family dashboard might need balances and categories, while a holdings drilldown can fetch positions only when someone opens it.
- Create an API key scoped to the organization.
- Fetch normalized accounts and balances for the overview.
- Load holdings and transactions lazily for detail screens.
- Cache non-sensitive display preferences separately from financial data.
Keep permissions explicit
"A family dashboard should clarify access, not quietly expand it."
Shared interfaces work best when every user understands which accounts are visible, who can invite new members, and which exports or automations are enabled. Organization scoping should be enforced in the API and reflected in the UI.
Ship the first version
For a first build, keep the dashboard boring: current net worth, cash runway, debts, upcoming recurring payments, and investment allocation. Once the data plumbing is reliable, the family can add the views that match how they actually make decisions.
