Issue a share certificate

POST /v1/captable/shares

Issues shares of a class to a stakeholder as a certificate: quantity, price and capital contributed, the vesting cliff and term, the legends on the certificate, and the issue, Rule 144, vesting-start and board-approval dates.

Both the stakeholder and the share class must already exist in this company, and the certificate id must be unused there — a reused id is a conflict, never a silent overwrite of an existing certificate.

Writes the caller's OWN cap table: the org resolved from the validated principal selects the tenant's store and scopes every row, so there is no field by which a caller can write into another company's table; a request with no validated org is refused. The whole write runs in one transaction, so a refusal leaves nothing behind. Validation is the cap-table bundle's and so is its refusal: a bad body comes back as {success:false, message, errors:[…]} with the failing fields listed, and numeric fields accept a number OR a numeric string. Bodies are capped at 1 MiB.

Request

The document declares no body for POST /v1/captable/shares. The handler is typed in cloud but its shape is not yet emitted, so the fields are not listed here — ask the MCP door's describe for post_captable_shares, which answers from the running route.

Response

The document declares no response body for this operation. It answers 200 on success and the platform error shape on failure — see Errors.
