# Reference for the 1Password Accounts API for Partners

> Complete reference documentation for the 1Password Accounts API for Partners.

This reference documents every endpoint for the 1Password Accounts API for Partners.

Each endpoint reference page includes the parameters, request and response schemas, and an interactive playground you can use to send requests. Select **Try it** in any endpoint header to open the playground, enter your own values in the input boxes, then send requests directly from the page.

<Warning>
  Requests you send from the API playground are routed through the documentation platform's proxy service. If you prefer to keep your bearer token strictly between your systems and 1Password, copy a code example and run it with your own tools instead.
</Warning>

For more information about authentication and how the Accounts API works, review the [API conventions](/accounts-api/conventions).
