API · Manage · Portfolios
Detach portfolio entity.
Detach an entity from a portfolio. Clears the entity's portfolio_id and returns the updated portfolio. The entity itself is untouched — detaching never dissolves, archives, or otherwise mutates the member.
Semantics - Idempotent: detaching an entity that is already detached returns the current portfolio state, no error. - Wrong portfolio: detaching an entity that is attached to a different portfolio returns 409 state_conflict naming the portfolio it actually belongs to — detach it there instead. - Opaque visibility: the portfolio and the entity must both live in your org and in the calling key's mode. Either one failing that check returns 404 not_found, indistinguishable from a missing id. See test mode.
