# maesn Connect

> Learn best practices for building authentication flows for your end users with the Maesn API.

## Authorize a single integration

You may want to create a user experience without integration selection and guide your end-user to directly authorize a specific integration.

When you create a URL to expose to your end-user (described in Step 2 of the [Quick start guide](/guides/quick-start)), add the identifier of the specific integration you want to display in maesn Connect's integration authorization component, e.g. `xero`.

A URL created with this parameter will cause the connect flow to open directly to the authorization dialog of just that integration.

```bash theme={null}
curl --request GET \
  --url 'https://api.maesn.dev/auth/xero' \
    -H 'x-api-key: YOUR_API_KEY'
```
