Scheduling review
Your booking pages, calendars, and tools listed, with your Calendly plan's limits checked against what you need.
The Problem
When Every Tool Has a Calendar and None of Them Agree
A calendar integration usually gets ordered after a double booking or a missed demo. Bookings land in one place, reschedules in another, and the CRM shows neither.
01 · Conflicts
Bookings clash with meetings on a calendar Calendly can't see.
Every calendar your team uses is connected for conflict checks.
02 · CRM entry
Reps copy each demo booking into Salesforce by hand.
Calendly's Salesforce app or webhooks create the lead and log the event.
03 · Reschedules
Reschedules leave the old time showing in the CRM.
Webhook events update or cancel the matching record when plans change.
04 · Tickets
Onboarding calls don't appear on the customer's ticket.
Calendly webhooks add each booking to the matching Zendesk ticket.
A client books a 2 p.m. call that clashes with a meeting on your Outlook calendar, because Calendly only checks Google. Your rep spends the morning copying demo bookings into Salesforce. Reschedules don't reach the CRM, so the old time still shows. Support books onboarding calls that don't appear on the customer's ticket. Your Klaviyo follow-up goes out a day late because someone exports the bookings first. Every tool has a calendar, and none of them agree.
We start by listing every calendar and tool a booking touches. In Calendly, we connect the right calendars for conflict checks, add Zoom links, and switch on the Salesforce or HubSpot app your plan supports. Where no app exists, we build with Calendly webhooks or the Google Calendar API, keeping sync tokens and watch channels healthy. Bookings land where your team works, not in someone's inbox.
Every calendar checked
Google, Outlook, and Exchange calendars connected so new bookings respect every existing commitment.
Reschedules that follow through
Reschedules and cancellations update the CRM, helpdesk, and email tools, not just the calendar.
Google's rules handled
OAuth consent, sensitive-scope verification, and watch channel renewals built into custom Google Calendar work.
Our Calendly and Calendar Integration Process
From Scheduling Review to Bookings That Land Everywhere in Five Steps
You see what your Calendly plan already covers, approve the calendar and field map, and watch test bookings update every tool before links change.
We map how meetings get booked today: which pages, which calendars, and where each booking should end up. Then we check your Calendly plan, since calendar limits, CRM apps, and webhooks depend on it. You get a written plan.
What's Included
What a Calendly Integration Covers
Most teams need the first three parts below. Apps, helpdesks, and multi-tool flows add the rest, and the plans show where each part starts.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites and business software for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Service Businesses Trust Us With Their Calendars
A missed or doubled booking costs a client's trust. These habits keep calendars accurate across time zones, tools, and Google's own rules.
Calendly features checked first
We check what your Calendly plan already includes before pricing custom work. If a built-in app or setting covers it, we'll tell you before we quote.
Time zones tested on purpose
We book test meetings from several time zones, including across daylight saving changes. Your clients see the right slot wherever they are.
Sync tokens kept current
Custom Google Calendar syncs store sync tokens and run a full resync when Google asks for one. Changes don't quietly stop flowing after a token expires.
Watch channels renewed on schedule
Google's push channels expire and don't renew themselves, so our code renews them on a schedule. Calendar changes keep arriving without a silent gap.
Narrow calendar scopes
We request only the Google Calendar scopes your app needs, which keeps Google's verification simpler. Your users see a consent screen that asks for less.
Accounts stay yours
Calendly, Google Cloud, and app credentials stay in your company's name. Changing developers later doesn't mean reconnecting every calendar or verifying your Google app again.
Overview
Who sets up Google Calendar integration with Calendly and your CRM?
DeveloperLook builds Google Calendar integration and Calendly setups for teams that book meetings every day. We connect the right calendars for conflict checks and sync bookings to Salesforce, HubSpot, or Zendesk. When your site needs its own scheduling, we build on the Google Calendar API.

Good fit
Service businesses booking from their website
Your clients book through a Calendly page on your Squarespace or WordPress site, and every booking must block time on the right Google or Outlook calendar.
Sales teams working in Salesforce
Your reps book demos in Calendly, and you need a Calendly Salesforce integration that creates the lead, logs the event, and assigns the right owner.
Support teams running Zendesk
Your support team books onboarding calls, and you want a Calendly Zendesk integration that adds each booking to the customer's ticket through webhooks.
Brands following up from Klaviyo
Your brand runs consultations and emails from Klaviyo, so you want a Calendly Klaviyo integration that starts a follow-up flow after each booking.
Product teams building scheduling into an app
Your app needs a Google Calendar integration of its own, with OAuth consent, two-way sync, and Google's verification for sensitive calendar scopes.
Not a fit
A full booking website
You need a booking website with payments, staff schedules, and client accounts, not a scheduling link. Our Appointment Booking Website Development page covers that build.
Field service jobs in Jobber
Your team schedules jobs in Jobber and customers book through your site. Our Jobber Website Integration Services page covers that link instead.
Patients booking into an EHR
Your clinic needs patients to book straight into an EHR or practice system. Our Patient Self-Scheduling Software Integration page covers those setups.
Solo with one calendar
You're one person with one Google calendar and a budget under $450. Calendly's own setup takes minutes, and we'll tell you before we quote.

Saimul IslamFounder & CEO, DeveloperLookStill have questions?
Send a message or book a call with the team.
Calendly and calendar integration with DeveloperLook starts at $450 for one team's calendars, Zoom links, and website embed. Booking syncs into Salesforce, Zendesk, or Klaviyo start at $1,400, and custom Google Calendar API builds start at $3,100. Calendly plan fees are paid to Calendly, and our fixed quote follows a free scheduling review of your pages and tools.
In Calendly, you open Calendars under Settings, choose Google, and sign in with the account you want to connect. Then you pick which calendars to check for conflicts and which one receives new bookings. The free plan connects 1 calendar, and paid plans check up to 6 per person, which matters when work and personal calendars are separate.
Yes. Calendly reads busy times from your Google calendars to hide taken slots, and writes each new booking to the calendar you choose. That's the core Google Calendar integration most teams need. When your own website or app must book into Google Calendar directly, we build that on the Google Calendar API instead.
Yes, on Calendly's paid plans, not the free one. Calendly's HubSpot app records booked meetings against contacts in HubSpot. Routing visitors by HubSpot data needs Calendly's Teams or Enterprise plan. HubSpot's free tier allows only a few custom properties, so we plan the field mapping before the app is switched on.
Yes, on Calendly's Teams plan or higher, with Salesforce Enterprise edition or above. A Salesforce admin connects it, and bookings then create or update leads, contacts, and events. On other editions, we build the Calendly Salesforce integration with webhooks. If you only need meetings mirrored, Einstein Activity Capture covers the Salesforce Google Calendar integration on supported editions.
Yes, through an embed. You copy the code from Calendly's Add to website option and paste it into a Squarespace Code Block, which needs a Squarespace Business plan or higher. Pop-up widgets may also need a header script. We set up the embed, check it on mobile, and match booking questions to your services.
Not directly anymore. Calendly stopped accepting new iCloud calendar connections in August 2024, though existing ones keep working. If you use Apple Calendar on a Mac or iPhone, connect the Google or Outlook calendar behind it to Calendly instead. Your Apple Calendar app then shows bookings as usual through that account.
Yes, one way. Jobber gives you a calendar feed URL that you subscribe to in Google Calendar, showing visits from 2 weeks back to 20 weeks ahead. Edits in Google don't flow back to Jobber, and Jobber says Google refreshes the feed about every 12 hours. For a faster link, our Jobber Website Integration Services page covers custom work.
Yes, one way. Asana can publish a project's or your My Tasks due dates as a calendar feed, which you add to Google Calendar from a URL. Tasks with due dates appear on the calendar, and changes made in Google don't go back to Asana. When tasks must book real time slots, we build a sync on both APIs.
Yes. In Google Calendar, you add an iCal or ICS link under Other calendars, then From URL, and Google shows that calendar beside your own. It works only for public or shareable links, and Google doesn't document how often it refreshes them, so updates can lag. For anything time-sensitive, we sync through the Google Calendar API instead.
