Front API Skill

Reference for Front REST API integration.

OpenAPI Spec

The full OpenAPI spec is in core-api.json (13k+ lines). Use it as the source of truth for:

  • Request/response schemas
  • Nullable fields
  • Enum values
  • Endpoint paths

Key Schemas

Message

  • recipients[].name - nullable
  • recipients[]._links.related.contact - nullable
  • recipients[].role - enum: from, to, cc, bcc, reply-to
  • author - nullable (null for inbound from external)
  • text - nullable (plain text version of body)

Conversation

  • assignee - nullable
  • recipient - nullable for some conversation types
  • tags - can be empty array
  • last_message - nullable
  • scheduled_reminders - nullable

Recipient

json
{
  "name": "string | null",
  "handle": "string (required)",
  "role": "from | to | cc | bcc | reply-to",
  "_links": {
    "related": {
      "contact": "string | null"
    }
  }
}

Common Gotchas

  1. Webhooks send previews only - must fetch full data via API
  2. Many fields nullable - don't assume presence, use .nullable() in Zod
  3. _links.related.contact - null when recipient has no contact record
  4. role includes reply-to - often forgotten in enums

SDK Location

@skillrecordings/front-sdk - Zod schemas should match this spec exactly.

Useful Endpoints

  • GET /messages/{id} - Full message with body
  • GET /conversations/{id} - Conversation details
  • GET /conversations/{id}/messages - Message history
  • POST /conversations/{id}/drafts - Create draft reply
  • GET /inboxes/{id} - Inbox details
