I have configured a python script that changes Email Signature of the user using gmail API. But the problem is by default it has the name as My Signature. Is there any way that I can use custom name instead of My signature?
And also is there anyway to create a new signature rather than updating My Signature. (Using GMAIL API)?
Using Gmail API to update/modify signatures will always apply to 'My Signature' which is the default signature for a gmail account.
If your only concern is changing/creating a new signature, you can always do it via Gmail directly.
