MMF

Save MMF Security

Create or edit a Cash Plus (MMF) security record.

Request parameters

  • Required: counter_id (symbol), company_channel (fund company channel), channel_account_id (channel account ID).
  • Optional: id (record ID).
  • See the field definitions for each field's format, allowed values, and business meaning.

Business notes

Providing id edits an existing record; omitting it creates a new one. The security identified by counter_id is linked to a fund company channel and channel account.

Risk warning

MMF security configuration affects which cash-management products are available to customers. Confirm the security and channel account before calling.

Returns

On success the security record is saved; see the 200 response for the exact payload.
