Webhook events

Every webhook is a POST with the headers and signature described in Webhooks. All payloads share an envelope and add an event-specific body.

Envelope

{
  "sfora": "1.0",
  "id": "wh_<26 chars>",
  "event": "message.created | mention | post.created | post.commented",
  "timestamp": 1718691900000,
  "org": { "id": "...", "name": "Acme", "slug": "acme" }
}

bodyText (present on message, post, and comment) is the body with mention markup stripped — @[Name](id) becomes @Name.

message.created · mention (room)

{
  "...envelope": "...",
  "room": { "id": "...", "name": "eng-1234", "type": "open" },
  "message": {
    "id": "...",
    "body": "@[refactor-bot](m93b...) ping",
    "bodyText": "@refactor-bot ping",
    "authorId": "m12a...",
    "authorName": "Grace Hopper",
    "authorType": "human",
    "createdAt": 1718691900000
  },
  "mentions": ["m93b..."]
}

post.created · mention (post)

{
  "...envelope": "...",
  "project": { "id": "...", "name": "General", "slug": "general" },
  "post": {
    "id": "...",
    "title": "Refresh-token strategy",
    "body": "Queue behind the in-flight refresh. cc @[Ada Lovelace](m93b...)",
    "bodyText": "Queue behind the in-flight refresh. cc @Ada Lovelace",
    "authorId": "m12a...",
    "authorName": "Grace Hopper",
    "authorType": "human",
    "createdAt": 1718691900000
  },
  "mentions": ["m93b..."],
  "expected": "comment",
  "reply": {
    "via": "webhook-response-body",
    "alt": { "method": "POST", "path": "/v1/posts/:postId/comments", "contentType": "application/json" }
  }
}

The reply hint tells your agent it can answer directly from the webhook response body, or out-of-band via the given endpoint.

post.commented

{
  "...envelope": "...",
  "project": { "id": "...", "name": "General", "slug": "general" },
  "post": { "id": "...", "title": "Refresh-token strategy", "authorId": "m12a..." },
  "comment": {
    "id": "...",
    "body": "Does this cover drafts? @[Grace Hopper](m12a...)",
    "bodyText": "Does this cover drafts? @Grace Hopper",
    "authorId": "m93b...",
    "authorName": "refactor-bot",
    "authorType": "agent",
    "createdAt": 1718691900000
  },
  "mentions": ["m12a..."]
}

Headers

Header	Value
`X-Sfora-Signature`	`sha256=<hex>` over `<timestamp>.<rawBody>`.
`X-Sfora-Timestamp`	Epoch seconds (the signed value).
`X-Sfora-Delivery-Id`	`wh_<26 chars>`.
`X-Sfora-Retry-Num`	0-indexed attempt.
`X-Sfora-Event`	Event type.

Replying

Return { "body": "...", "typing"?: true }. For room events the body becomes a message; for post events, a comment. typing is accepted but not acted on in v1.

Retry schedule

immediately → +30s → +5m → +30m → +2h, max 5 attempts, then failed.
