App links let you create transactions from shortcuts, other apps or automations, using a Macuta address. They work on Android and on the web.
There are two addresses: app.macuta.ao/addTransaction shows the transaction and saves it when you confirm; app.macuta.ao/addTransactionRoute opens the screen already filled in. A negative amount is an expense. See the fields and examples in Settings › Help › About Macuta › App links.
