List check-in events

GET https://app.honeybadger.io/v3/projects/{project_id}/check_ins/{check_in_id}/events

Required scope checkins:read

Returns a check-in’s events, newest first. A report payload over 50 KB is stored truncated: it’s replaced by _truncated: true, a _message, and the _original_size in bytes.

The first page is always the newest events; follow links.older for earlier ones. links.newer is always null and has_newer always false.

Example request

curl "https://app.honeybadger.io/v3/projects/$PROJECT_ID/check_ins/$CHECK_IN_ID/events" \
  -H "Authorization: Bearer $HONEYBADGER_API_TOKEN"

401 Unauthorized

The credential is missing, invalid, expired or revoked (unauthorized), or was sent in a way v3 doesn’t accept (see the examples).

Example payload: unauthorized (Missing, malformed, expired or revoked credential)

{
  "error": {
    "code": "unauthorized",
    "message": "Access denied"
  },

  }

  },
  "meta": {
    "request_id": "abc123"
  }
}

Example payload: credential_in_query (Sent as the `auth_token` query parameter)

403 Forbidden

The credential isn’t allowed to do this. error.code says why. An account or project the credential doesn’t cover is 404 not_found, not 403.

Example payload: access_denied (The credential isn't allowed to do this to this record)

{
  "error": {
    "code": "access_denied",
    "message": "Access denied"
  },
  "meta": {
    "request_id": "abc123"
  }

Example payload: insufficient_scope (The credential lacks the permission this endpoint requires)

{
  "error": {

      "token_scopes": [
        "faults:read",
        "insights:read"
      ]
    }
  },
  "meta": {
    "request_id": "abc123"
  }
}

Example payload: requires_user_token (The endpoint records who acted, and an account token has nobody)

{
  "error": {
    "code": "requires_user_token",
    "message": "This endpoint records the person who acted, so it requires a user credential rather than an account token"
  },
  "meta": {
    "request_id": "abc123"
  }
}

Example payload: project_restricted (A project-restricted credential cannot create a project)

{
  "error": {

422 Unprocessable Content

No path names the account, so the API token has to. This is returned when the token covers more than one account and the account a request applies to cannot be determined. Use a token bound to a single account.

Example payload

{
  "error": {
    "code": "ambiguous_account",
    "message": "This credential covers more than one account, so the account a request applies to is ambiguous. Use a token bound to a single account."
  },
