Create multiple Pricing Segment rules with REST API

Does the API '/fscmRestApi/resources/11.13.18.05/pricingSegments' creates multiple Segment rules in one POST operation.

Creation of one segment rule is working fine.

When trying to create multiple segment rules in one operation(POST), getting Error 'invalid attribute "null" in the payload'

Please let us know if someone encountered this or any way to create multiple segment rules in one operation
