Price_rule REST API discount code handle issue

[shikhas20]

I have created a price_rule API. In this API, I have already set

customer_selection=>prerequisite,

prerequisite_customer_ids=> $customerIds

We are sending single discount code with multiple user.

If User A send his discount code with User B and User C, User B used that discount code then no other User C is not able to use that discount code even User A also.

How can I manage this?
