SITE_SEND_PASSWORD Site Endpoint
  /rpc/site/?method=SITE_SEND_PASSWORD  
  The Email will come from the 'Email' column on SETUP_SITE_MANAGE. You either need to be using your own email sending, or have this email verified as per Email Sending  
  PARAMETERS TYPE NOTES
  Document Numeric Optional. The Id of the Document if you have a custom lost password document. This document needs to have the tags [LOGON], and [PASSWORD], or alternatively [JSONCOMBINED64].  JSONCOMBINED64 gives a base 64 encoded object of the Logon and Password.  It does not offer more security, but looks better if exposed to an end user.  You can also have your own tags to pass additional information. These fields must start with TEMPLATE_.  For example, you could have [TEMPLATE_PARAMETER1], and then pass TEMPLATE_PARAMETER1=fred
  ExpirePassword Text (1) Y / N [default]. If 'Y' the password will be set to have expired yesterday
  Logon Text Mandatory. User's Logon
  MySiteOnly Text Y/N. If Y, it will only email if the Logon is in your site
  NoSystemTemplate Text Y/N. If Y, your standard email template will not be applied to the email
       
  template_xyz Text You can also pass additional fields to be merged into your template document. For example, in your document you could have '[template_xyz]'. Then if you pass 'tamplate_xyz=abc', then the value of abc will be subsituted in. As a note, you need the square brackets ('[', ']') around the field, and the field must start with 'template_'.
