Profile 1.0 (via Shotgun) email invitation?

Hi,
Something new is happening on our side. We’re using the python API to update a Person, when doing so an email is sent with the following content:

Subject: profile 1.0 (via Shotgun)
Message (html): invited you to the Shotgun site [ACCEPT INVITATION]

Not sure what is triggering this email?
Thanks

Hi @eeight,

This is the welcome email to the user you add onto Shotgun. When you add a user via Web app, a welcome email will be sent to the user’s email used to create the account and he/she could click Accept Invitation to set his/her password.

It usually looks as below:

Is it not what you are seeing?

Hi eeight!

What fields are you updating on the HumanUser record, exactly? Did this human user already exist, or were you creating them initially via the API?

Yes, this is what I see (but there’s nothing before “invited you” (in your case Ben Xu). I am not using the Web app.

Using the python API, I simply modify the user (not creating the user, and yes this HumanUser was created via the API initially). Updating custom fields (not email, login or other builtin fields).

I didn’t have this email before (let’s say 2-3 months ago).
Any ideas?
