API
You might say
My website needs data from the backend. People keep saying I need an API—what is that?
An agreed way for two pieces of software to request and return informationFor example, a weather app can ask a weather service for today's Shenzhen forecast and receive the temperature and conditions. The API defines where the request goes, what it carries, and what comes back; it is not the page, backend code, or database.

Saving produces no result. Inspect the API URL, method, submitted data, status, response body, and how the page handles it. Fix the cause, save again, confirm the response matches the contract and the page shows the right result; if it persists data, refresh to confirm it remains.
