Trigger Authentication

Stack Exchange uses OAuth authentication. When you connect your Stack Exchange account, Pipedream will open a popup window where you can sign into Stack Exchange and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Stack Exchange API.

Pipedream requests the following authorization scopes when you connect your account:
