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
For example:
https://hyperdrivepro.morethanrewards.com/ClientTouch.aspx?AddContacts=123|124|125|126|127
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.
