Create an SAP Web Service Consumer (calling External Web Service from ABAP)
Create a Function Module and full the below Code :
Sample code :
DATA: http_client TYPE REF TO if_http_client,
      host_str TYPE string VALUE 'www.myservice.in',
      service_str TYPE string,
      path TYPE string VALUE  'my path',
      errortext TYPE string. "used for error handling
DATA  : wf_string1 TYPE string,
         lw_inputs TYPE string,
         error_text type string,
         subrc TYPE SY-SUBRC,
         lw_outputs TYPE  string.
CALL METHOD cl_http_client=>create_by_url
  EXPORTING
    url                = 'myurl'
  IMPORTING
    client             = http_client
  EXCEPTIONS
    argument_not_found = 1
    plugin_not_active  = 2
    internal_error     = 3
    OTHERS             = 4.
  IF sy-subrc <> 0.
*  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
*             WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
CALL METHOD http_client->request->set_header_field
  EXPORTING
    name  = '~request_method'
    value = 'POST'.
CALL METHOD http_client->request->set_header_field
  EXPORTING
    name  = '~server_protocol'
    value = 'HTTP/1.1'.
CALL METHOD http_client->request->set_header_field

CALL METHOD http_client->request->set_header_field

concatenate 'data u need sned' into wf_string
CALL METHOD http_client->request->set_cdata
