Queued items come back with `status: "queued"`; poll `GET /submissions/{id}` for `sent`. When no mailbox is connected the submissions are still recorded (`status: "recorded"`, `meta.warning: "no_email_sender"`) for the team to send from the app. Lenders that already have a submission on the deal are left unchanged and listed in `meta.already_submitted`; lenders without a submissions email are listed in `meta.not_sent`. This sends real email — **always pass an `Idempotency-Key`** so a retry cannot submit twice. ## OpenAPI ````yaml /openapi/public-v1.json post /v1/deals/{dealId}/submissions openapi: 3.0.0 info: title: NextLevel MCA Public API description: >- REST API for the NextLevel MCA deal platform. Objects flow Businesses → People → Deals → Submissions → Offers → Advances. **Authentication.** Send `Authorization: Bearer ` with an API key (`nlmca_live_…`, created in Settings → Developers) or an OAuth access token. Keys are scoped to one location. **Conventions.** JSON only. Cursor pagination (`limit` ≤ 100, `cursor` from `meta.next_cursor`). Every success is `{ data, meta }`; every error is `{ error: { type, message, code, param, request_id } }`. POST endpoints accept `Idempotency-Key` (24h replay). Rate limit 300 requests/min per credential (`X-RateLimit-*` headers). **Scopes.** Keys with no scopes have all of them.
