API + Webhook Help

As soon as I click on the On/Off toggle button, it brings me this pop-up.The chatbot couldn’t understand the issue, and I don’t know why this is suddenly happening… as I was able to switch easily from 15-min to 30-min previously. 

I would like if Calendly would add the option to add more than one phone number for a contact. I have several clients who have a cell and office number to save or when you have a client that shares an email address (husband & wife) and you want to include them both as a contact, that way you can have each of their numbers listed and who it belongs to.

Dear Calendly Team,I see this has been asked many times over so this is nothing new to you. The last I read about it was 30 days ago.Essentially, when will Calendly join the list of these Reserve with Google partners? https://www.google.com/maps/reserve/partners?ihs=3This is such a key feature for those who have a local business and rely on people booking an appointment to benefit from a service. I understand that Calendly might have initially been designed with corporate meeting organisation in mind, but there is a demand (judging by this forum) for it to cater more to small businesses and sole traders who rely on booking appointments as a source of customer contact.Like others, I am contemplating shifting away from Calendly (my yearly plan will be up for renewal in December) if this is not something that is comi

I am experiencing a critical and intermittent issue with a Round Robin event type.The Problem: It’s not happening with every bookin. the assigned host is not receiving an email notification and the event is not being added to their Google Calendar. Meanwhile, the invitee receives everything perfectly (Zoom link, confirmation email).This has already caused us to miss calls because the host simply didn't know the event existed.Key Details: Event Type: Round Robin (2 seats). Status: Some events sync perfectly; others simply never reach the host's inbox or calendar. Since the invitee is successfully notified, the trigger is firing, but it seems to be failing specifically on the host-side delivery for random instances.Is anyone else experiencing this in

Hi,We need to set up per-host ceilings in a round robin through the API.In other words, as we create the round robin event via the API, we would like to instruct that for this event, agent A cannot have more than X appointments in total and agent B, no more than Y appointments in total (on the same round robin event).This limitation prevents us from using the round robin feature (which is why we haven't yet upgraded to a higher plan which would include round robin).I’d be happy to provide more context for you if needed.

Trying to book a meeting and getting an error message preventing me from scheduling. Why?“Too many requests. Please try again later.” TIA

Bonjour,Lorsqu’une réunion est replanifiée, il n’est plus possible de “planifier l’invité à nouveau” à partir de cette dernière réunion. Est-ce normal? c’est très embêtantMerci

Bonjour,Je rejoins les demandes précédentes. Quand le bouton “RESERVER EN LIGNE” sur la fiche d’établissement Google My Business sera t’il disponible? Je regarde pour une autre solution que Calendly même si j’en suis satisfaite pour le reste.Merci

Hello All! I would like to display my availability without allowing booking.I want to disable or hide the "NEXT" button booking option while still showing my schedule. The "NEXT" button is shown after a client chooses a day on the booking calendar.I can add CSS and PHP functions in WordPress if this helps find a solution.

Hi, I’m Akshat.While building an AI agent to manage my own calendar events, I stumbled onto an idea that I can’t ignore a meeting scheduler that understands context, not just time.Since then, I’ve spoken with several SaaS founders and sales teams, and a recurring friction keeps coming up with current scheduling links:What breaks today:Your calendar knows when to meet but not who booked or why.High inbound volume leads to important meetings getting lost among generic ones.Manual lead qualification before every call wastes time and mental energy.Context is scattered across emails, DMs, CRMs or missing entirely.So meetings often start with guesswork instead of clarity.I’m exploring whether this is a problem worth solving with:a conversational booking layerAI-based intent captureautomatic pre-call summariesNot pitching anything yet genuinely trying to validate if this pain is real and common, or ju

We have embedded Calendly across many of our websites (different domains and platforms) and it seems that the widgets fail to load randomly, displaying this:After refreshing (sometimes several times) it goes back to normal. Is there an outage?  

We are trying to use the embedded booking widget on our website and it works well except when our site is in dark mode. I provide custom colours using the ?background_color=xxx&text_color=xxx&primary_color=xxx options. It works well but the generated iframe has a white background instead of being transparent. The generated Calendly iframe does support a transparent background colour but the generated iframe needs to have this added into the head section:<meta name="color-scheme" content="light dark">I found the fix here: https://stackoverflow.com/a/77604431/343If I manually add this tag using the browser inspector it works fine and the iframe has a transparent background again. Is it possible to have this tag added to the generated iframe so that we can have full dark mode support? Thanks!

I book clients for personal training sessions and “Schedule Event” is not very suitable. I’d much rather it said “BOOK NOW” or “REQUEST TO BOOK” or just “SCHEDULE”. Is that possible??

I’m sharing this post to help provide clarity for other European, service-based businesses evaluating Calendly.Over the past months, I’ve had multiple conversations with Calendly support regarding EU-native payment methods—specifically iDeal, which is the standard payment method in the Netherlands and widely expected by customers during booking flows.Through these discussions, support confirmed the following: Support for iDeal and similar EU payment methods is not currently available in Calendly’s booking payments. This request has already been submitted in the past by multiple users and exists as an internal feature request. Support can only add additional votes/requests to this item. The feature is not currently on the product roadmap and has no ownership or planned timeline.

I initially set the  Invitee limit to a group event to 10.I later on decided to change it to 9 (I needed to save a spot for someone).It did display 9 in the event itself, but as people kept booking, the emails I got sent still displayed “X of 10”.Today, the 10th spot was booked without me having changed it back to 10 (thankfully, it was by the person I’d saved it for).So it seems that if you change the Invitee limit AFTER you’ve created the event, it doesn’t work.Am I missing something?

When I build one-on-one meetings under my personal profile, I can select multiple durations. Unfortunately, the feature to add multiple durations is not available for Managed Event Types. This feature is available for individual event types, where you can add up to four duration options per event type, but it does not apply to Group events or Managed Event Types. It would be great if this feature could be added to Managed Events so I can easily share meeting templates with my team without having to manually copy templates I’ve developed from my personal profile with each new employee or meeting type developed within my team.

Hi all, I’ll preface by saying I’m not a developer by profession, so my code might not be up to industry standards. I’ve created a tool for work called “multi_cal” that has a few utility features that Calendly does not offer (or only partially offers) on its own. Currently, it is based in Google Apps-Script and runs off a host email account that communicates with Calendly via workflows. I recognize that this is probably inefficient, but there are two reasons for this: the first is that, as stated, I am not a developer, and the second is that I wanted other people in my department to be able to set it up for themselves relatively easily and without requiring intervention on my part (that made fiddling with OAuth and other intricacies a little out of scope). The FeaturesShared Resource KeywordsCalendly is great for managing a single individual’s calendar, but it starts to struggle when di

Hi everyone,I'm using the Calendly inline widget on my website and I'm consistently seeing this deprecation warning in my browser's developer console: Unload event listeners are deprecated and will be removed.1 sourcefbevents.js:196🔍 InvestigationAfter investigating, I confirmed:The warning comes from Facebook Pixel ( fbevents.js ) which is loaded by the Calendly widget My website has no Facebook Pixel code—this is entirely from Calendly's widget script ( assets.calendly.com/assets/external/widget.js )⚠️ Why This MattersModern browsers (Chrome, Edge, Firefox) are deprecating unload event listeners because they:Block the back-forward cache (bfcache) → Slower navigation

Problem statementI’m integrating Calendly’s scheduling widget into my website using the official embed script (<script src="https://assets.calendly.com/assets/external/widget.js"></script>).When Calendly’s script injects its <iframe> into the DOM, it does not include an allow attribute that permits use of the Payment Request API.As a result, browsers log the following console warning:[Violation] Permissions policy violation: payment is not allowed in this document. and payment methods like Apple Pay and Google Pay do not work inside the embedded Calendly iframe, even when Stripe is connected. Proposed solutionTo fix this, the iframe generated by your embed script should include an attribute like:<iframe ... allow="payment *; publickey-credentials-get *;"></iframe>

if i create a one on one meeting , should this activity hit the group  level  webhook ?

For my company internal use, will it be doable to set a webhook to company internal domain name or url?

Hi Calendly team and community,We support several US and UK based businesses that rely on Calendly for scheduling paid calls, demos, and services. Many of them are now expanding into India and are running into challenges around accepting local payments, especially UPI, without forming an Indian entity.Currently, these companies are using Merchant of Record and payment facilitation models such as (removed by moderator), which helps foreign businesses sell in India without local incorporation and enables UPI alongside standard credit card processing.Our questions are: Does Calendly support UPI or other India specific online payment services for paid bookings? If not, is there a recommended way to integrate Calendly with external payment processing services or Merchant of Record platforms? Are there any plans on the roadmap to support localized payment methods like UPI in addition to credit card pr
