How to restrict mismatching data when multiple RITM's are created at a time through 3rd party

[Muneera]

Hi All,

My requirement is to create RITM through 3rd party by using scripted rest API. To populate the catalog item variables based on the payload using cart JS in the scripted  rest API. While testing multiple RITM's, if 2 or 3 RITM's are created at a time without having seconds time difference, the data sending in the payload by 3rd party is getting correctly in ServiceNow logs, but when the RITM is created in ServiceNow the variables data populating in the catalog item variables is getting mismatched.

Need help as soon as possible to restrict data mismatching.

Thanks & Regards,

Muneera.
