I have configured One way authentication mode and able to connect to the server successfully.
After getting socket ID, I am using AT+SOCKW command to POST and GET.
e.g.
AT+SOCKW=00, 18<CR> (18 length is example)
POST /api/Frames HTTP/1.1<CR><LF>
DATA......
<CR><LF>
AT+SOCKW=00,18<CR>
GET /api/Contracts HTTP/1.1<CR><LF>
<CR><LF>
and in response always getting HTTP:400 Bad request error.
Please give a technical person contact number of ST employee, or please suggest solution on this.

Hello,
I think you are doing the right think but probably your request is incorrect.
I mean, some headers (like Host, Content-Length in POST request) may be missing. Some fields are mandatory, others may be required by the web server and leading to a Bad Request reply if they are not sent by client.

Thanks for your feedback.
Could you please confirm, how to configure/send header contents ?
How to send it?
POST /api/Frames HTTP/1.1<CR><LF>
HOST:***.com
Content_length: xx
Data..............
<CR><LF>
is this correct way ?
Can i use "HTTPPOST=url,path,data,443<CR> "
to post data to https server?

Hello,
your header seems correct (just need to add a <CR><LF> at end of every header lines).
I suppose you are using SPWF01 for this, AT+S.HTTPPOST does only perform http requests and does not support https (that are based on TLS) requests.
For a normative reference on HTTP 1.1, I kindly suggest to have a look to RFC2616 (and updates).
You may also exercise with others application: for example if you have a Linux machine then you might try the following to get a valuable header:
nc -l 12345 | xxd -g 1 &
wget --post-data "This is a test POST message" -q http://localhost:12345
You can also get this kind of info from developer tools of your browser.
