# Adding App Authentications

> Reduce friction when adding an authentication to your own app.

### Adding an authentication to your own app

<Steps>
  <Step title="Confirm your app's `authentication_fields`">
    When you created your app in the Zapier Developer Platform, a required step was to [define the fields required for authentication](https://platform.zapier.com/build/auth). Depending on your authentication scheme the `authentication_fields` below will differ.
  </Step>

  <Step title="Form & send your request">
    Leveraging the [Create Authentication](/powered-by-zapier/api-reference/authentications/create-authentication) endpoint, supply your app's required `authentication_fields` in the request.

    <CodeGroup>
      ```js Example with Basic Authentication theme={null}
          // POST /authentications
          "data": {
              "app": "{MY_APP_ID}",
              "title": "{AUTHENTICATION_NAME}",
              "authentication_fields": {
                  "username": "{MY_USERS_USERNAME}",
                  "password": "{MY_USERS_PASSWORD}"
              }
          }
      ```

      ```js Example with API Key Authentication theme={null}
          // POST /authentications
          "data": {
              "app": "{MY_APP_ID}",
              "title": "{AUTHENTICATION_NAME}",
              "authentication_fields": {
                  "api_key": "{MY_USERS_API_KEY}",
              }
          }
      ```
    </CodeGroup>

    Be sure to supply whatever `authentication_fields` are required by your apps' authentication scheme.

    <Tip>
      Pick an authentication name that'll be recognizeable to a user should they find it outside of this flow, such as "Carter's LinkedIn Authentication", or "Micah's Slack Authentication"
    </Tip>
  </Step>

  <Step title="Leverage the new authentication in subsequent workflow steps ✨">
    A successful response from this request will include an `id`, which can be used in subsequent steps.
  </Step>
