Integrations

Everything you already use, wired into your calendar.

Calendars, Slack, HubSpot, and webhooks on Pro and Studio. Stripe, Google, and Instagram on every plan.

Pro+

Google Calendar

Two-way sync: bookings land on your Google Calendar and your personal events block your availability — automatically.

Settings → Google Calendar

Pro+

Apple Calendar, Outlook & any calendar

A live, read-only feed of every booking. Subscribe once on your iPhone, Mac, Outlook or Google (“From URL”) and appointments show up like any other event.

Integrations → Calendar feed

Pro+

Slack

New bookings, requests, cancellations, reschedules, payments and new clients post to a channel — with an “Open in SendLynx” button.

Integrations → Slack

Stripe

Deposits and card payments go straight to your own Stripe account. We never hold your money, and add nothing on top of Stripe's fee.

Billing → Payouts

Pro+

HubSpot

New clients become HubSpot contacts and confirmed bookings log as meetings on their timeline.

Settings → HubSpot

Pro+

Webhooks

Signed, real-time HTTPS webhooks for bookings, payments and new clients — to your own server or any app that accepts a webhook URL.

Developers → Webhooks

Google Business Profile

Your Lynx Link becomes the “Book” button on your Google listing. On Studio, review requests route to your Google profile too.

Reviews → Google

Instagram & Facebook

A “Book now” button on your profile that opens your Lynx Link — set up in a minute from the Integrations page.

SendLynx Partner API

A scoped OAuth 2.0 REST API with signed webhooks for trusted partners — the SendLynx Agent (Quickflo) books through it.

Developers

Third-party names and marks belong to their owners and are used to show compatibility — not endorsement.
