Detect 12v wet contact with IFTTT

Which NCD product should I buy to detect 12v wet contact with IFTTT triggers.
I’m looking for the family “Channel General Purpose SPDT Relay Shield + 7 GPIO with IoT Interface” or the family “Channel Solid State Relay Shield + 7 GPIO with IoT Interface”, but I can’t find electical information on the input part.
Can someone give me info/advice to achieve my goal ?

thank you
