Create Jenkins Job remotely with REST API

I can't create Job remotely (REST API + Postman), I try

POST:

http://localhost:8080/createItem?name=NEWJOB

OR

http://localhost:8080/job/NEWJOB/build

and always have 403 error(GET methods work).

Here I see that I need to create config.xml for POST :

https://issues.jenkins-ci.org/browse/JENKINS-9410?focusedCommentId=204821&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-204821

I don't understand how to create this config? Do I need this config? How to create jenkins Job remotely?

It takes me several steps:

1) GET

http://localhost:8080/crumbIssuer/api/json 

+header Authorization ..................... Basic YWRtaW46YWRtaW4=

Value of Authorization field was created when I put in login and password(admin,admin in my case).

After this query I saw next:

{
    "_class": "hudson.security.csrf.DefaultCrumbIssuer",
    "crumb": "2ad62df85d23d4c65a25c0b33fb0ef61",
    "crumbRequestField": "Jenkins-Crumb"
}

2)Next step -> create config.xml

I just take it from another jenkins job (named test) manually when I :

GET http://localhost:8080/job/test/config.xml

+header header Authorization .............. Basic YWRtaW46YWRtaW4=

3)Create job:

POST http://10.14.48.107:8080/createItem?name=NEWJOBNAME

+header Authorization ........ Basic YWRtaW46YWRtaW4=

+header Content-Type ........... text/xml

+header Jenkins-Crumb ......... 2ad62df85d23d4c65a25c0b33fb0ef61

I take this header name and value from 1st query crumb

After this step I have had nothing as answer, but job was created remotely!
