Unable to register bank adjustments via rest api v1

I want to register banks Adjustments through api v1 in epicor version 10.2.300.30.

So far I have been able to enhance the registration of the new group

[POST] [/BankAdjEntries]
https://ad/ERPTest/api/v1/Erp.BO.BankAdjEntrySvc/BankAdjEntries
Response Code 201

But when trying to perform the register of the new Adjustment, it tells me the following.

[POST] [/BankTrans]
https://ad/ERPTest/api/v1/Erp.BO.BankAdjEntrySvc/BankTrans
Response Body
`{ "HttpStatus": 400, "ReasonPhrase": "REST API Exception","ErrorMessage": "Use

**GetNewBankTran1**

method to get new BankTran record.","ErrorType": "Ice.Common.BusinessObjectException",`

but when dealing with GetNewBankTran1 method, I see that the answer it returns is (200), which indicates that it can only modify an existing record (or I am wrong ?)

[POST] [/GetNewBankTran1]
https://ad/ERPTest/api/v1/Erp.BO.BankAdjEntrySvc/GetNewBankTran1

Response Code
200

so no error but , not record is registered to DB.

I hope someone can give me an idea of ​​what I am doing wrong and / or I am overlooking to be able to make this record

Thanks in advance.
