# Add and update contacts with the Loops API

> Loops provides a REST API to manage your contacts.

With [the Loops API](https://loops.so/docs/api-reference/intro.md), you can easily manage contacts directly from your application or service.

For example, creating a new contact is as easy as sending a `POST` request to `https://app.loops.so/api/v1/contacts/create`.

```json theme={"dark"}
{
  "email": "test@example.com",
  "firstName": "Adam",
  "lastName": "Kaczmarek",
  "favoriteColor": "blue",
  "userGroup": "Founders",
  "source": "Signup form Service"
}
```

We also offer endpoints for finding, updating and deleting contacts (plus some other features like sending transactional email and sending events).
