Affiliate assign to order via hook

[FFOX]

Hello!

I have a question: how can I use a hook to add a partner to an order?
I know that you can add a partner via the WHMCS admin area on the order page, but I need the same functionality via a hook.

Can you tell me which direction to go? Is it enough to create an entry in the affiliatesaccounts table? Or there is a ready-made function, for example, as in WHMCS I noticed a query:

jQuery("#affiliatefield").html(jQuery("#affid option:selected").text()); jQuery("#modalAffiliateAssign").modal("hide"); WHMCS.http.jqClient.post( "orders.php", { action: "affassign", orderid: 307, affid: jQuery("#affid").val(), token: "" } );
