MngCreateClientLoginLink

Creates a one-time link that opens the trading terminal signed in as one client, without the client's password. The manager opens the link in a browser, and the terminal exchanges the code from the link for a customer session through AuthCustomerByCode.

The command is available through the manager command API only; there is no REST path for it. The kind is fixed by the command name, so customer_kind is not accepted on input. The lead counterpart is MngCreateLeadLoginLink. See Clients and Leads Commands.

The link:

• has the form https://<terminal_host>/<language>/platform?code=<code>, where terminal_host is taken from the client's brand and language is the client's preferred_language, then the brand default_language, then en;
• contains a 64-character code that is valid for expires_in seconds (60);
• can be used once. The first exchange attempt consumes the code, whether it succeeds or not;
• is a secret. The server keeps only a hash of the code, and the login_url value is masked in the journal.

The session created from the link is a full customer session: everything the client can do in the terminal is available. It differs from a normal sign-in in three ways:

• it carries impersonated_by with the manager id, and every journaled action in it records impersonated_by in the journal detail;
• it expires 4 hours after the exchange. An open WebSocket connection receives session.update with action: logout and is closed;
• it does not change the client's last_login_time.

The client is not notified.

Access Control

Allowed sessions:

• SESSION_MANAGER
• SESSION_ADMIN
• SESSION_DEALER
• SESSION_CRM_MANAGER
• SESSION_CRM_ADMIN

The caller must have CRM access and login_as_clients. The record brand and desk must be inside the manager scope; admin scope bypasses this check. Every call is journaled.

The client must be enabled, have at least one trading account, and belong to an active, enabled brand that is available for the API and has a terminal_host.
