you would use the Refunds API(which accepts an amount) to return funds to the customer(what you call client)

https://stripe.com/docs/api/refunds/create#create_refund-amount

[karmic prairie]

you mean this?
$stripe->refunds->create(['payment_intent' => 'pi_Aabcxyz01aDfoo', 'amount' => 1000]);

and then if you want to pull money from the connected account(what you call the contractor), you separately call the TransferReversal API https://stripe.com/docs/api/transfer_reversals/create)

[karmic prairie]

for return part money?

[lunar geyser]

yes
