POST methods getting converted to GET

I am using _ redirects file to call external services hosted on another domain. All type of requests GET , PUT and DELETE works fine expect the POST request. whenever my application makes POST request it gets rewritten to GET and then my server returns 500 error, since there is no URL exists there.

Here is the content of my _redirects file.
/api/v1/* https://test111.herokuapp.com/api/v1/:splat

Any clue, what configuration changes required to make this working for POST requests too ?

Thanks
