Aman,

What data do you have?
You'll need a CSV file with user email addresses.
You'll need a template signature file.
You'll need the values to put into the signature; these can come from the CSV file or diretly from user attributes.

You need to create one CSV that has email, name, title and will look something like:

user,Salutation,LastName,FirstName,Position
mousem,Mr,Mickey,Mouse,Actor
duckd,Miss,Daisy,Duck,Actress

and a signature template file (eg signature.txt) that has the signature with the placeholders Saultation, LastName, FirstName and Position, I used an HTML content even though it has the txt extension, like:

<html>
Regards<br>
<style="bold">{Salutation} {FirstName} {LastName}<br>
{Poistion}<br>
</html>

then run the command 
gam csv StaffList.csv gam user "~user" signature file signature.txt html replace Salutation "~Salutation" replace FirstName "~FirstName" replace LastName "~LastName" replace Position "~Position"

Aman,

The values like this "~user" have to mthc the headers in the csv file; you need "~User".

Hello Aman,

You have been given this. By the look of it, you work for a software company. You should be able to show this to someone in your company who should be able to explain it in your native language.

The command to use GAM is all one line and has the special characters tilde and quotes and is

gam csv StaffList.csv gam user "~user" signature file signature.txt html replace Salutation "~Salutation" replace FirstName "~FirstName" replace LastName "~LastName" replace Position "~Position"

assuming you have a csv file named StaffList.csv and contains the minimum header line and at least one user line, using the headers above such as this

user,Salutation,LastName,FirstName,Position
aman....@jungleworks.com,Mr,SAINI,Aman,"Customer Services"

If you call your html signature file signature.txt even though it is an html file, you can cut and paste the command line above and it will work

Thanks I struggled with this also.  I got it to work but i noticed that several of my end users created multiple signatures.  is there a way through GAM to make "My Signature" the default for new and replies.

There was a command to set default to new and replies?

There was a command to clean a user signatures before force the new one?

On the command:

gam csv signature-data.csv  gam user "~email" signature file template-sig2.txt html replace Phone "~Phone" replace Name "~Name" replace email "~email" replace Position "~Position"

Could be a tag to set the name of the signature?

Thank you,

No

gam user us...@domain.com signature ""

[name <String>] sets the display name for non-primary sendas addresses, not the name of the signature, as that isn't possible via the API.

If you have a current default signature, the API will update that, but if you delete it, it seems that the API will not over-write any of the other signatures, but instead add a new signature called My signature. 

f you rename that signature, the API will keep on updating that same signature, and not touch the other signatures.
