Platform capabilities

Everything you need for conversational messaging

Unified threads, real-time events, and AI-powered automation across every channel.

Unified thread across channels

Customers start on WhatsApp, continue on SMS, or follow up through Chat -- all within the same thread. Message formatting adapts to each platform automatically.

Channel fallback routing

If a message cannot be delivered on the primary channel, it automatically falls back to an alternate channel. SMS serves as the ultimate fallback for critical messages.

Real-time WebSocket events

Get instant message updates, typing indicators, and read receipts through a persistent WebSocket connection. No polling required.

Conversation state management

Track conversation status, participant presence, read receipts, and typing indicators out of the box. Focus on your UI, not the plumbing.

Five channels supported

SMS, WhatsApp, Chat, Facebook Messenger, and MMS. Customers choose their preferred channel; you see a single unified thread.

AI auto-reply generation

Sakura AI reads incoming messages, references your knowledge base, and drafts accurate responses. Set confidence thresholds to auto-send or queue for agent review.

  author: "agent",
});

// Listen for replies
client.conversations.onMessage(conversation.sid, (msg) => {
  console.log(`Customer replied: ${msg.body}`);
});

Frequently asked questions

Common questions about the Conversations API.

The Conversations API lets you manage two-way messaging threads across SMS, WhatsApp, Chat, and Facebook Messenger through a single unified API. Instead of managing each channel separately, you create a conversation and send messages -- we handle routing and delivery on the right channel.

The Programmable Messaging API is optimized for one-way and simple request-reply messaging like notifications and OTPs. The Conversations API is built for ongoing, multi-turn dialogues where context and history matter -- customer support, sales conversations, and interactive commerce.

Yes. A conversation can start on WhatsApp and continue on SMS or Chat. The API maintains a single thread with full message history regardless of which channels are used during the conversation.

Use our webhook events to sync conversation events with your CRM in real time. Every message, status change, and participant event triggers a webhook. We also provide pre-built integrations for popular helpdesk platforms.

Each conversation supports up to 50 participants, which covers virtually all customer engagement scenarios. For broadcast use cases where you need to reach more people simultaneously, use the Programmable Messaging API instead.

When enabled, Sakura AI reads incoming messages, understands intent, and generates contextually appropriate responses. You can configure the AI with your business knowledge base, set confidence thresholds for auto-sending, and define escalation rules for complex queries.

By default, conversation data is retained for 12 months. You can configure shorter retention periods for compliance, or extend retention with our archival add-on. All data is encrypted at rest and in transit.

The Conversations API is priced per active user per month. An active user is any unique participant who sends or receives at least one message in a billing period. Message delivery costs (SMS, WhatsApp) are billed separately at standard channel rates.

Yes. You can build fully automated conversation flows, integrate with chatbot frameworks, or combine AI auto-replies with human agent handoff. The API supports both programmatic and human participants in the same conversation.
