Slottable SMS Integration

A booking operator can use Slottable’s registration events to notify people at the point their status changes. Registrant Stage Changed can trigger a Mobile Message SMS through Zapier, while Contact Changed can create or update a Mobile Message contact when a registrant’s details are updated. This gives the team a practical way to mark important changes without checking every record manually.

A stage notification might tell a registrant that their place has moved to the next step, or alert an organiser that someone requires follow-up. The exact message depends on the data Slottable supplies and the rules you set in Zapier. Mobile Message can also add a contact to a list when a suitable Slottable event provides a phone number. The connection is not a native booking system or a two-way sync. It is a one-direction Zap that takes one Slottable trigger and runs one Mobile Message action. With clear stage definitions and carefully selected recipients, the workflow helps limited-slot operators communicate changes while keeping the booking record in Slottable.
