R4X library httpPost

Can the httpPost command in the R4X library be used to send a HTTP POST request?
e.g. sending a Json {“data”:100} to an IP address

// Creates an HTTP POST request and optionally returns the received data.
// Note. Endpoint should include the initial "/".
// The UBlox device stores the received data in http_last_response_<profile_id>

                             char* responseBuffer, size_t responseSize,
                             const char* sendBuffer, size_t sendSize, uint32_t timeout, bool useURC)
