You can add contacts to ClientTouch (for the currently logged in user) by sending the user to a special URL.
Use a pipe character “|” to separate the Contact IDs and put them in the AddContacts querystring parameter of ClientTouch.aspx
Valid Contacts IDs for that user will be added to ClientTouch, then the user will be redirected to the ClientTouch Actions tab.
Things to consider
- User must be logged in to the system
- ClientTouch may not automatically cleared out, based on the configuration of your server
- There is a maximum length for URLs. It may limit this solution to a few hundred IDs.
