Frequently asked questions

Everything you need to know about building on Facebook Messenger with Sakura SMS.

The Messenger API lets your application send and receive messages on Facebook Messenger programmatically. Through the Sakura SMS platform, you connect your Facebook Page, authenticate via OAuth, and use our unified REST API to send text, images, templates, quick replies, and structured messages to any Messenger user who has opted in to your Page.

Log in to your Sakura SMS dashboard, navigate to Channels, and select Facebook Messenger. You will be prompted to authenticate with Facebook and grant page-level permissions. Once authorized, your Page is connected and ready to send and receive messages. The entire setup takes under five minutes and requires no code changes on your end.

The Messenger API supports text messages, images, videos, audio, files, quick replies, buttons, generic templates (carousels), receipt templates, and persistent menus. You can also send structured messages with call-to-action buttons that link to URLs or trigger postback events in your application.

Facebook enforces a 24-hour standard messaging window. After a user messages your Page, you have 24 hours to respond freely. Outside this window, you can only send messages using approved Message Tags (for confirmed event updates, post-purchase updates, or account updates) or Sponsored Messages (paid). Sakura SMS automatically tracks window status and warns you before sending outside the window.

You can build fully automated Messenger experiences using our API. This includes welcome messages for first-time visitors, keyword-triggered auto-replies, conversation flows with quick reply branching, handover protocol to escalate from bots to human agents, and webhook-driven responses based on events in your application. Our Conversations API manages state across the entire thread.

The Sakura SMS dashboard provides real-time metrics for your Messenger channel including messages sent and received, delivery and read receipts, response times, conversation volume trends, quick reply tap rates, and handover events. All data is available via the REST API for integration with your own analytics tools.
