Let clients reply STOP or cancel by text

Set up text replies so a client can stop your texts or cancel their next booking by replying, and let missed calls trigger a text back.

  1. 01

    Use a gateway that forwards replies

    Replies reach Setvos only through an SMS gateway of your own that forwards them: Twilio, SMSAPI or seven.io, connected on Integrations › SMS gateways. TurboSMS, AlphaSMS and SMSClub do not forward replies, and neither do texts sent on the Setvos allowance.

  2. 02

    Give the gateway its reply address

    Open the “Inbound webhooks” card on Integrations › SMS gateways and press “Generate secret”. Copy the whole reply address for your gateway into the vendor’s settings straight away: the full address is shown only once. Generating and rotating the secret needs a role that can change messaging settings.

  3. 03

    Know what a reply does

    Setvos reads the first word of the reply.

    • STOP, or the same word in your clients’ languages such as СТОП, stops every SMS, WhatsApp and Viber message to that client, reminders included, and every automatic message on any channel.
    • A cancel word such as CANCEL or СКАСУВАТИ cancels the client’s next upcoming booking, under your usual cancellation rules.
    • Anything else is simply recorded. From a client who holds a seat in a group class, the cancel word cancels that seat, never the class.

    Text back missed calls

    The same card has the “Telephony: missed calls” address. Paste it into your telephony provider’s settings, then switch on “Missed-call text-back” on the “Automations” tab of Messaging (SMS).

  5. 05

    Find the replies

    A reply appears on the “History” tab of Messaging (SMS) with “From” and the client’s number under “To”, their words under “Message”, the type “Reply” and the status “Received”.

Common questions

I rotated the secret and replies stopped arriving. Why?

The old addresses stop working the moment a new secret is issued with “Rotate secret”, which is why it asks you to confirm first. Paste the new addresses into the vendor’s settings.
