AT commands for HTTP request 5G Development kit

Is there any manual for sending AT commands for HTTP requests, especially GET, POST with custom headers? The Quectel_RG50xQ_RM5xxQ_Series_AT_Commands_Manual_V1.2.pdf provided on the documentation of the product does not include commands for HTTP communication. I have found Quectel_LTE_Standard_HTTPS_Application_Note_V1.1.pdf and some other materials but I am having some issues with setting the request header.


You can refer to the attached document.

Thank you for the document. Sorry for asking again but I am new to using the Quectel RM502Q-AE module and AT commands in general. I want to send a GET request to a server that has Api key on headers, and when I use AT+QHTTPCFG=“requestheader”,1 I get OK as response, without given the option to input values. Also, when I test command: AT+QHTTPCFG=? I get this output:
Picture1 not the same as on the document provided:

Any suggestion?
Will it be able to send the latest version of firmware? It currently have this RM502QAEAAR11A04M4G_01.004.01.004
