**Sources** lists every way people get into this custom, and where you add
another. A custom used to have a single door — its quiz. It can have several at
once now, and they all feed the same [People](/en/customs/people/) table.

Each way in gets a row: your quiz, each webhook, and one per CSV you've uploaded.
The quiz sits among them like any other source, with the switch that decides
whether its link is live. Turning it off hides the quiz and leaves your questions
and answers untouched — a custom can take people only from a webhook or a
spreadsheet.

**Add a source** and **Import a CSV**, at the top, add one. Once this custom has
a webhook, the delivery log stands below the list: every delivery, accepted or
rejected, and exactly what was sent.

- **[Bringing people in](/en/customs/people/bring-people-in/)** — setting up a
  webhook or a CSV import, and what happens to people once they've arrived.
