If Hello Hotel doesn't have a native integration with one of your tools, Zapier is how you bridge the gap. The integration provides two webhook endpoints that any platform capable of sending an HTTP POST request can use — Zapier, Make, n8n, or a custom script your team builds.
Use the send-sms webhook to text guests directly from your Hello Hotel number, triggered by events in your other systems. When a new reservation is created in your booking platform, send a personalized welcome text. When check-in day arrives, send arrival instructions and door codes. When a guest checks out, trigger a thank-you message or a review link. Every automated message appears in your shared Hello Hotel inbox just like a regular text — so your team has full visibility into what's been sent and can pick up the conversation if the guest replies.
The update-contact webhook creates or updates guest contacts in Hello Hotel based on phone number. When a new guest is added to your CRM or a row is updated in your guest spreadsheet, the contact flows into Hello Hotel automatically. Hello Hotel matches contacts by phone number — if the number already exists, the record is updated rather than duplicated. This keeps your guest contact list current across systems without any manual entry.
The Zapier integration handles data coming into Hello Hotel, and Hello Hotel's built-in automations handle data going out. Set up outbound webhooks to notify your other systems when things happen in Hello Hotel — a guest sends a message, a voicemail comes in, a conversation status changes. Create a task in your project management tool when a guest reports a maintenance issue via text. Log guest interactions to a spreadsheet or CRM. Send a Slack notification when a VIP guest messages after hours. The combination of inbound webhooks and outbound automations means Hello Hotel fits into your existing workflows in both directions.
Enable the integration under Settings → Integrations in Hello Hotel. You get an API key and documentation for both endpoints right on the integration page. In Zapier, create a new Zap with your trigger event, add a "Webhooks by Zapier" POST action, paste in the Hello Hotel URL and your API key, map your fields, and you're live. The whole setup takes a few minutes per workflow.
Hotels use the Zapier integration to send check-in reminders from PMS systems that don't have a direct Hello Hotel integration, send welcome messages when new bookings come in, sync guest contacts from spreadsheets or CRMs, trigger post-stay follow-ups and review requests after checkout, and alert guests about property events or seasonal information. If your PMS has a native Hello Hotel integration (like Mews), use that for guest context and reservation data — and use Zapier for everything else in your tech stack.
