How to push GCLID to ZOHO CRM

Hi EveryOne,

I have done with integration between ZOHO CRM & Google Adwords but want to know what would be the placeholder for these highlighted part below in my third party web form. : -

val="GCLID"> CMPjuu-Xx78CFRSTjgodPHsA3Q</FL> </row>

For reference - https://www.zoho.com/crm/help/google-adwords/configure.html

Include the "GCLID" variable in your existing API script as shown in the sample below to transfer the tracking details.

<Leads> <row no="1"> <FL val="Lead Source">Web
Download</FL> <FL val="Company">Your Company</FL>
<FL val="First Name">Hannah</FL> <FL val="Last
Name">Smith</FL> <FL val="Email">testing@testing.com</FL>
<FL val="Title">Manager</FL> <FL
val="Phone">1234567890</FL> <FL val="Home
Phone">0987654321</FL> <FL val="Other
Phone">1212211212</FL> <FL
val="Fax">02927272626</FL> <FL
val="Mobile">292827622</FL> <FL
val="GCLID">CMPjuu-Xx78CFRSTjgodPHsA3Q</FL> </row>
</Leads>

Note :- GCLID needs to push in ZOHO, we have done all script part etc. but confused to what value must put on those highlighted yellow placeholder.

Thanks
