I'm looking into adding a list of contacts to my gmail account as I will need to export contacts from software and then automatically upload these contacts to my gmail account. I've been looking into this and there is a lot of information about OAuth but this all seems to find the users google account and allow me to make changes to that, which is far more complex than I need.
I was thinking it should be something like this:
<HTTPRequest url="https://www.google.com/m8/feeds/contacts/default/full" operation="POST" _Authorization="CLIENT_ID">
<HTTPRequestData>
SEND DATA HERE
</HTTPReuestData>
</HTTPRequest>
but I have no idea how to specify that I want to update 1 specific gmail account. Is this possible?
Unfortunately there is no other way to access Google API or protected data stored on Google services without using OAUTH 2.0 protocol. Hope this helps you!!
