Front App

API token auth: Authorization: Bearer {api_token}. Tokens from Front Settings → API & OAuth → API Tokens. Account-scoped. HTTPS enforced. OAuth2 for multi-account Front apps. Webhook signature: Front signs payloads (x-front-signature header, HMAC-SHA256). Rate limiting: per-token, plan-dependent (typically 1000 req/min for Pro). Channel types: email, SMS, chat — each requires appropriate inbox configuration before use.

Standard HTTP status codes with JSON error bodies ({status, message}). 429 for rate limits. 400 for missing required fields or invalid conversation ID format. Conversation IDs use cnv_ prefix; message IDs use msg_ prefix. Webhook delivery: Front retries failed deliveries. Conversation search: paginated, uses cursor-based pagination. API channel: required for programmatic message creation — set up in Front as an "API" type channel. Front uptime at status.frontapp.com.

Front is a shared inbox platform where teams collaborate on customer conversations across email, SMS, chat, and social channels. For agents: the REST API enables creating inbound conversations, adding replies to existing conversations, tagging conversations for categorization, updating conversation assignee and status, and searching conversation history. Webhook subscriptions push conversation lifecycle events (created, replied, tagged, archived) to agent endpoints. Official Node.js SDK simplifies integration. Confidence is docs-derived.

REST API at api2.frontapp.com. Resources: conversations, messages, contacts, accounts, teammates, inboxes, channels. GET /conversations lists conversations (filter by tag, status, assignee). GET /conversations/{id} retrieves a conversation with messages. POST /channels/{id}/messages creates a new inbound message (via API channel). POST /conversations/{id}/messages adds a reply to a conversation. POST /conversations/{id}/tags adds a tag. PATCH /conversations/{id} updates conversation (archived, trashed, assignee). GET /contacts/{id} retrieves a contact. POST /contacts creates a contact. GET /search/conversations searches conversations by query. Webhooks: subscribe to conversation.created, message.received, conversation.archived, conversation.tagged events.
