The following details will be made available for each expense at the /api/v1/centers/:id/expenses endpoint:

• name of expense
• amount
• boolean informing if the expense is recurring

There will also be POST, PUT and DELETE versions of the same endpoint for adding new expenses and modifying/deleting expenses.

The endpoint /api/v1/centers/:id/expenses/paid will be made available for retrieving and updating the amount of paid expenses for the chosen month.

The endpoint /api/v1/centers/:id/expenses/balance will be made available for retrieving the balance (total amount paid for all months - total expenses for all months).

@edmondpr Do we need to support role based access to centers expenses ? Should all roles be allowed to see expenses ?
