Post operation of creating user with Trips failing

[RoronoaSrinu]

We are from Adobe System part of the AEM Forms Product team.
We were trying to make use of your APIs for an internal PoC.

We are using HTTP requests :
https://www.odata.org/getting-started/understand-odata-in-6-steps/

In the process we encountered some trouble.
When we try to submit user details along with trip data, the POST call fails. It doesn’t accept the key ‘Trips’ in the Request body of the object.

However, when we do a GET to retrieve existing data, we are able to see the key ‘Trips’, with value populated under it.
