IBFT Inquiry Status REST 1.2

Dear 1LINK Support Team,

We are currently testing the IBFT Pull API (/uat-1link/sandbox/ibft-pull-rest-service/path-1) in the 1LINK Sandbox environment.{
"ResponseCode": "90",
"ResponseDetail": "CUSTOMER NOT FOUND"
}
However, we are encountering an issue where our API request consistently returns the response:

Below is the request payload we are using:

{
"PAN": "ciujnuv",
"TransactionAmount": "000000105500",

• Hello everyone, I am new here. I don't know how to consume 1LINK APIs for IBFT. Where can I get client ID from? Can anyone tell me in detail about this?
