Cherry cannot observe the fax itself, so this is you telling it the form was sent. A `ready_to_file` application may also be marked filed directly, for the operator who prepares and sends it without e-signature. ## OpenAPI ````yaml /openapi.json post /ein-applications/{id}/mark-filed openapi: 3.0.3 info: title: Cherry API version: 1.0.0 description: >- Cherry's public developer API — programmatic access to a business's books as Cherry keeps them: bank transactions with their categorizations, the chart of accounts, the double-entry journal, financial statements, legal entities, the tax-obligation calendar, the fiscal health score, and company incorporations (formation, EIN, and state filings). Authenticate every request with an API key: `Authorization: Bearer ck_live_…`. Keys are created in the Cherry app and are scoped to one business (tenant) — there is no tenant id in any URL. Keys carry a `read` and/or `write` scope; every GET needs `read`, mutations need `write`. Conventions: successful responses wrap the payload in `{ "data": … }`; list endpoints add `{ "meta": { "pagination": { limit, offset, nextOffset } } }` — pass `nextOffset` back as `offset` until it is null. Errors are `{ "error": string, "reason"?: string }` with conventional status codes. Dates are `YYYY-MM-DD`; money amounts are numbers in the row's currency. Requests are rate-limited per key with token buckets (429 + `Retry-After` when exhausted); report generation has a smaller budget than plain reads. servers: - url: https://api.trycherry.ai/v1 security: - bearerAuth: [] tags: - name: Transactions description: Bank feed rows and their categorizations. - name: Accounts description: The tenant's chart of accounts. - name: Bank accounts description: >- Connected bank accounts — Plaid-linked and manual.
