# Session API



This is a Server-to-Server API that accepts order parameters as input and returns the SDK payload and payment link.


### Implementation Details



To implement payment locking, include the payment locking payload in the `payment_filter` parameter when calling the session API. Please note that all fields are **case sensitive** .
