Rest template exchange method working incorrectly

Question

I am consuming another restful web service that's https inside my rest WS. When I am running my application on localachine the code works fine. But as soon as I deploy it and then access my application through that url, that rest template call written inside my code gives 400 error.

Here is the log trace

400 Bad Request

Check your request xml....you are missing some mandatory attributes ...Get the request xml from logs and do a check in postman — VelNaga, Jul 12 '18 at 13:41
400 means it hits the server but some problem in your request xml — VelNaga, Jul 12 '18 at 13:41
I checked it when I run the same code on local machine that rest template call works fine....but as I deploy my application on server and tries to hit it via rest client, the rest template call gives 400 error — Shivam Saxena, Jul 12 '18 at 14:53
restTemplate.exchange(url, HttpMethod.POST, entity, String.class); — Shivam Saxena, Jul 12 '18 at 15:03
This is the call written inside my code which works fine when I run my application on local machine. Bit gives 400 when the deployed jar is hit through(the route is my request hits apigee tool and then it comes to my deployed jar) — Shivam Saxena, Jul 12 '18 at 15:04
The entity you are posting is wrong....Your local machine and host machine both points to the same endpoint of the webservice? — VelNaga, Jul 12 '18 at 15:10
Yes same.And for the entity..that piece of code works fine on my local machine — Shivam Saxena, Jul 12 '18 at 15:22
something you are missing in your request a header or content-type etc in your requets — VelNaga, Jul 12 '18 at 15:41
Share your postman call or curl here and share the entire client code....Let's see what could be the issue — VelNaga, Jul 12 '18 at 16:17

I checked it from server some how application was not able to pick one header which was the problem....but thanks for all the suggestions — Shivam Saxena, Jul 13 '18 at 07:51

Probably there should be an issue in your request. Either you are missing mandatory request parameters in your request XML or missing some headers which throw this 400 Bad request exception.
