API + Webhook Help

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

We are integrating the Calendly Scheduling API with our agentic system and are facing unexpected behavior while booking meetings.Request Payload{ "date": "2025-12-19", "time": "02:00", "email": " [removed by moderator] ", "name": "name" } Response Received HTTP Status: 200 Response Body: { "status": "error", "message": "I encountered a system error while booking.

Hi Team, I want to verify what is the meaning of this message: “stytch_block_verdict:true” in a post request with 200 response. 

HI team,I am using a citrix application to connect to calendly with my users, I had a problem to verify the schedule a meet and the .har file is giving me this error:  "method": "POST", "url": "https://calendly.com/api/booking/invitees", "response": { "status": 400,  "text": "{\"failure\":{\"error\":\"Oops, something went wrong.\",\"code\":\"forbidden\",\"context\":{\"telemetry_id\":\"tid-3f6fcd30-751f-4f1a-8468-25ece116e58f\",\"explanation\":\"Your meeting request could not be finalized with this host. If you feel you've reached this message in error, please reach out to support with below error code.\",\"stytch_block_verdict\":true}}}" }, Is this because in Calendly platform is blocking me with the IP address we are using?  It works outside the citrix, should we ask for a whitelist in Calendly side, how ca we do that? 

Hey! I have this site where I want to embed a Calendy form. Sadly, once I embed the Calendy in my site with the cookie banner hidden, it still shows the cookie banner.  As you can see in the image, I have embedded the Calendy. But on the left it says “?hide_hdpr_banner=1” (this is directly from the “hide cookie banner” function when embedding my Calendy) What to do?

Hi! I was trying to fetch group_relationships with owner parameter →https://api.calendly.com/group_relationships?owner=https://api.calendly.com/organization_memberships/ef4f9092-0e84-43cc-960c-b82804f7f9fdI am getting following 403 error →{    "title": "Permission Denied",    "message": "You do not have permission to access this resource."}I’m using PAT token to make API call, and the PAT is generated from an Owner account still getting same issue. I’ve tried with OAuth2 as well but facing same issue

An error occurredThe operation couldn't be completed.(CalendlyKit.APlError error 1.) every time I go into clients details this shows up! I am unable to access what I need to do to complete my sessions 

I work overnights and need my meetings to extend from 10pm to 6am. I use the workaround solution to make it work but I’d really like to have this as a legit option. Please allow overnight meetings!! 

Hi everyone, I’m having an issue with embedding Calendly on my website. The inline embed sometimes loads normally, but other times it gets stuck on a blank frame or keeps showing the loading spinner. I’ve already tested it on different browsers and even disabled caching plugins, but the problem still appears randomly.Has anyone experienced unstable behavior with the Calendly embed on their website? Are there specific script settings, domain configurations, or recommended practices to make the embed load consistently?

Hi there, Our customers have repeatedly reported that they are not receiving any SMS notifications from Calendly. We created a new workflow to test if the issue was related to the previous setup, but the problem is still happening.This situation occurs very frequently, even though our SMS content is very basic and does not contain any URLs or restricted terms. For example, today our customers has been waiting for over 3 hours and still has not received the SMS.Is there any known issue with SMS delivery at the moment?Any guidance or clarification would be greatly appreciated.Thank you!

Is there a way to force Calendly when rescheduling a meeting via a reschedule link to limit it to a specific team member? I have team members that need to reschedule a meeting, and they find that when they do so using the reschedule link, it may get assigned to a different person in the round robin group, however they actually just want to move their own meeting from 12 to 11 for instance. They can do this on the Calendly portal, by choosing ‘choose team member’, but they would like to be able to control who it is rescheduled without leaving our CRM via a reschedule URL.   

Hello,with the embedded Calendly version and data-resize=”true”, it’s now possible to set the correct height automatically. Thank you very much for it.Unfortunately, there is still a huge invisible padding/margin around the calendar inside the iFrame. How it is possible to remove it?I used the negative padding hack here on my website: https://www.shop-studio.io/en/contact. The solution is “ok” but not responsive in every case (see mobile). As you can see, the loading spinner is performing a “layout shift” during loading.Thank you in advance!

I’m using Calendly for internal booking inside our company, and I wanted to ask if there is a way to enable manual confirmation for bookings.

Hi everyone,I’m currently trying to set up a workflow in Calendly that redirects users after they book a meeting to a custom thank-you or resource page with important instructions and helpful links.I see there’s an option for a redirect URL, but I’m not sure how to customize it per event type or add multiple resource options.Is there a way to dynamically change the post-booking page based on the event selected?Or do I need an external integration like Zapier or webhooks for this?For reference, here’s an example of a resource-style page format:Streaming Resource PageAny guidance or best practices would be greatly appreciated! Thanks 😊

Hi there,after connecting our new Salesforce Org to the existing Calendly Account, connection is no longer working.We don’t receive any Calendly Action on Salesforce side by synchronizing the push events to Salesforce.Support quite immediately needed.  Thanks in advance.Regards, Jasmin

I want the connect button to always show register/login page but Calendly automatically loads an account which is already logged in browser.So, If user is a first time visitor in my site and requires connecting to my app’s dedicated Calendly account, it fails cause they already have an personal account and it loads automatically .I can add condition that current account doesn’t match with app’s account using DB, but then how to prompt the register page frommy account?

I’d like to find out if Calendly can be made to feed appointments into ChiroTouch software, a chiropractic office management system. It seems ChiroTouch is a bit behind the times in developing their extensibility and have no way patients can make appointments online. The most they can do is provide a server password for their chiro client’s appointment database and Calendly ‘capabilities’ (APIs, make, zapier) would need to take it from there.I’m not a developer so I don’t know what database specifics are needed, but assuming it’s straightforward, can anyone estimate a range of time and cost for something like this?

I am trying to upgrade my plan for the first time from the free plan, but every time I hit purchase I receive “Server error. Please try again”.Can I get some help with this please, or I will have to look for another scheduling service.I have already cleared my cache, used another browser, internet is working great and I do not have any extensions running. Thanks!
