Method	`POST`
Operation	`post_captable_shares_transfer`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Moves shares from one stakeholder to another.

Omit quantity to transfer the whole certificate, which REASSIGNS it and mints no new share. Send a quantity below the amount held to SPLIT it — the source certificate keeps the remainder, and a split additionally requires certificateId for the new certificate, which must be unique in the company. A quantity outside 1..held is refused, so a transfer can never over-issue.

Both outcomes answer 200: a transfer records a movement between holders and mints no security of its own, which is why this is not a 201 the way an investment is.

Request

4 fields, body application/json (required).

Field	In	Type	Required	Description
`certificateId`	body	any	—	CertificateID names the NEW certificate a partial transfer issues, and is required for one — a partial transfer without it is refused 400.
`quantity`	body	any	—	Quantity is how many shares to move. OPTIONAL, and its absence is not zero: omitted or null transfers the WHOLE certificate.
`shareId`	body	any	—	ShareID is the certificate being transferred.
`toStakeholderId`	body	any	—	ToStakeholderID is who receives them. Required, and it must reference a stakeholder of the SAME company; one that does not is refused 400 rather than creating…
