Script for adding signature using PNG

[Nikolay G]

I am trying to deploy a signature using a PNG file but the error I get when using 

gam user <user id> signature file signature.png png

gives this error

signature.png, 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte

Is it even possible to import it as PNG or I should use only HTML.

Additionally if it is possible, what would be the command from a CSV with each user having a separate signature file as png?

Hi Nikolay,

I think the signature file needs to have the HTML code to display the image, like you would on a webpage. You can just add an image as a signature directly.

WRT CSV, this looks more complicated. I haven't done this but from looking into it, it looks like you need to have a file as the base signature, but you can use Tag Replacement to change this based on the values in a CSV. This page covers the tag replacement https://github.com/taers232c/GAMADV-XTD3/wiki/Tag-Replace#user-attribute-replace-tag-userreplacement-processing and this helpsheet from Kim (https://goo.gl/DXmmsB) runs through the process.

Hope this helps

My recommendation is to set one user's signature using the Gmail UI however you want it to look, then run:

gam user <user> show signature

to see what it looks like and modify as you need for others.

Hi Jay,

Nikolay is looking to update users via a CSV file. So once you have the signature, is it possible to have this 'code' in a cell of a CSV to update the users? My understanding is that you can only update using a file.

I finally got an html file from my customer.

I was reviewing the file James sent but I am having issues running the command with the examples in it.

I printed the signatures with csv headers and so on but for some reason whenever I run the command for "UsersWithoutSignature", gam doesn't execute anything and doesnt show me an error. It just shows a new line and asks for a new command.

I don't have experience with html or python so maybe I am doing something wrong.

My understanding is that in the html file I need to replace the name with a {string} i.e. instead of Nikolay G > {firstName} {lastName}. Same goes for phone, title etc.

I've done that already on the file and now I am trying to get a command on GAM to pull the headers from the csv with the strings, place it on the html and set it as signature for the user. I can also provide the html file as well if that's alright.

Command I used was: gam csv UsersWithoutSignaturesOU.csv matchfield orgUnitPath "^test" gam user ~email signature file sign.txt html replace firstName ~firstName replace lastName ~lastName replace title ~title replace email ~email
