API

Last updated March 5, 2025

Loops provides a REST API to manage your contacts.

With  the Loops API , 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.

{ "email": "adam@loops.so",
  "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).

 Go to our API reference  for a full guide.
