In the example above, select which API endpoints should send notifications; for instance, if you connect only to our SMPP - US endpoints, deselect the others to avoid notifications from them.    Important information regarding Component Groups:   External connectivity - Sinch will use these components to announce external maintenances and incidents within our major carrier network, or if a Sinch internal incident causes disruption to our carrier network. API Groups (Messaging API, Conversation API etc) - Sinch uses these components to announce direct maintenances and incidents that impact customer-facing APIs. We recommend subscribing only to the regional API endpoints you actively use. Use the quest mark tooltip to identify which FQDN belongs to each component.   Dashboard.sinch.com and similar groups - Subscribe to these components for updates about our self-serve services, support portal, and analytics tools.    If you do not deselect any components and subscribe to all, you will automatically subscribe to any future components when they are created. If you customize your subscription, you will not automatically receive updates for new components.    When signed up and the options have been selected, it’s important you activate your subscription by verifying the method you have selected (for email/SMS).   Once verification completes, you will be ready to receive notifications.      Manage your subscription    For email  After you verify your email subscription, you receive a confirmation containing a link to manage it:    manage your subscription.jpg And when you receive email updates, a link to manage your subscription appears at the bottom of each message:    subscription management link.jpg Click the link to view the page listing the components you subscribe to. On that page, select or deselect components to change your subscription.      For SMS  Each SMS notification you receive includes a link. You can follow this link to visit the subscription management page, where you can update your preferences or unsubscribe from specific components or all SMS updates.      For Webhook  Each webhook notification includes a documentation URL and link to unsubscribe. To update subscription preferences, contact Sinch Support.    Learn more about the Sinch Status page.  ... View more
