# Oauth1 authentication

> Used to make for HTTP requests that require OAuth 1 authentication.

Authenticates a connection with services that use OAuth 1. There are two ways to do this, and you pick one with the authentication type. **Three-legged** OAuth is for services that require a user to log in and grant permission; you reference a token you obtained through that login flow. **One-legged** OAuth is for direct system-to-system access, where you sign each request yourself with a consumer key and secret plus an access token and secret.

This documentation describes: [Schema](/schemas/http-authentication-configurator/oauth1-bearer)

## Fields

<FormField property="oAuthType" label="OAuth Authentication Type" required>
  How the connection authenticates. Choose **Three Legged** when a user login and permission are required, or **One Legged** for direct system access. Defaults to **Three Legged**. Your choice decides which fields appear below.
</FormField>

### Three Legged

<FormField property="token" label="Token" required diType="oauth1-token-reference">
  The OAuth 1 token reference obtained through the user login flow. Select an existing token reference here; Alumio uses it to sign each request.
</FormField>

### One Legged

<FormField property="signature" label="Signature" required diType="oauth1-signature">
  The method used to sign and secure requests. Select the signature type the service expects.
</FormField>

<FormField property="consumerKey" label="Consumer key" required>
  The public identifier provided by the service for your application. You can store the value in an environment variable and reference it here.
</FormField>

<FormField property="consumerSecret" label="Consumer secret" required>
  The private key used to sign requests, provided by the service. Keep it private; you can store it in an environment variable and reference it here.
</FormField>

<FormField property="accessToken" label="Access token">
  The access token provided by the service. You can store the value in an environment variable and reference it here.
</FormField>

<FormField property="accessTokenSecret" label="Access token secret">
  The secret paired with the access token, used to securely sign requests. Keep it private; you can store it in an environment variable and reference it here.
</FormField>

## Sample data

This feature configures a connection rather than transforming data, so there is no before/after to show. A one-legged setup looks like this:

| Field                     | Value                      |
| ------------------------- | -------------------------- |
| OAuth Authentication Type | `one_legged`               |
| Consumer key              | `your-consumer-key`        |
| Consumer secret           | `your-consumer-secret`     |
| Access token              | `your-access-token`        |
| Access token secret       | `your-access-token-secret` |
