API + Webhook Help

Apologies if the title isn’t using the right terminology. I am building a web app that embeds another company’s Calendly widget into it for easily scheduling a meeting. I want to be able to use the response from the calendly scheduled event and get information about the meeting the user just booked but without having full access to the partner’s calendly instance. Is there a way to issue API tokens that only allow my company to access bookings made via the widget on our website? Like I said, we are partners with the other company so we have a good relationship but they don’t want to grant us full access to their Calendly, which is understandable. Just trying to find a good balance here so we can still display the scheduled event information to our users from our app.

HiI want to Integrate Calendly with Vertical CRM (ZOHO CRM application) so there are some values I need from calendly for the Integration. Please refer the screenshot belowCan you help me finding Signup URL, Refresh Token URL, Access Token URL, client id and secret etc. for my account 

Handle Message Function:const handleMessage = (event) => {const { data } = event.nativeEvent;try {const parsedData = JSON.parse(data);if (parsedData.event === "calendly.event_scheduled") {console.log("Event scheduled successfully");} else {console.log("Received Calendly event data:", parsedData);}} catch (error) {console.error("Error parsing message from WebView:", error);}}; const calendlyUrl = "https://calendly.com/yourUrl"; Injected Javascript:const injectedJavaScript = `(function() {var script = document.createElement('script');script.src = 'https://assets.calendly.com/assets/external/widget.js';script.async = true;script.onload = function() {Calendly.initInlineWidget({url: '${calendlyUrl}',parentElement: document.getElementById('calendly-container'),prefill: {},utm: {}}); window.addEventListener('message', function(event) {if (event.data.event) {window.ReactNativeWebView.postMessage(JSON.stringify(event.data));}});};document.head.appendChild(script);})();true;`;Web View compone

I’ve successfully created a webhook. However, it only triggers when an event is created or cancelled if I am simultaneously logged on to the Calendly web page. I understood it would run on every event called by the trigger.  I am trying to work out if this is by design (and I’m misunderstanding how they work) or the result of a misconfiguration.  NB I’ve created the webhook using the API Key and an oath token with the same result. What I’m trying to achieve is:Create a single use link using the API have a user book an event have that event trigger a webhook (calling an http trigger in PowerAutomate)I hope some can help. 

Is it possible to add new contact and create booking through the API?  

Can we get the following features for No-Shows?Ability to change meeting to No-Show in App. Cancel meeting is the only option available. Follow up text and email messages.

When we reschedule an event in calendly and then call scheduled_events end point in API, it returns two events, one with status cancelled with older time slot and another with status active with new time slots. In this case how can i infer that the second event in actually the reschedule of first event?

Hi I have been trying to fix an issue with calendly where when i get to the you are scheduled screen it breaks my form… you can see it breaks out of the mobile phones screen / viewport and enlarges the screen. I can then move this page around with my finger. the steps with in the calendly form before this are all perfect. I have tried many different solutions but it will not fix the issue.SO: What happens:Calendar selection, time selection, and "Enter Details" steps all render correctly within the mobile viewport When the confirmation/"You are scheduled" page loads inside the iframe, the entire page layout expands beyond the screen width The form's title/description become oversized and cut off on the right The user can scroll/pan horizontally (page is wider than the viewport) This persists when navigating to subsequent screens Pinching to zoom out snaps it back to the correct scaleWhat  tried (none worked):overflow: hidden !important on the .calendly-inline-widget and its iframe max-w

When using the following API end point https://stoplight.io/mocks/calendly/api-docs/395/event_typesfor fetching the List Of User's Event Types we have the option to sort and fetch the events on the basis of name using the sort option in the query parameters as mentioned here https://developer.calendly.com/api-docs/25a4ece03c1bc-list-user-s-event-types sortstringOrder results by the specified field and direction. Accepts comma-separated list of {field}:{direction} values. Supported fields are: name. Sort direction is specified as: asc, desc.Default:name:ascExample:name We see that there is no other option we can pass. Is there a way we can fetch the events based on the update_at of an event in descending order?FYI: We are integrtating calendly in our CMS app, where we are making request to calendly to list user's events. It gives default 20 events sorted by NameThis will be not useful if user has multiple events and hence looking for a way to fetch latest updated events of user.

I’m reaching out to request a critical feature for Calendly’s API: an endpoint to schedule events programmatically without requiring invitees to select a time slot via a scheduling link. This capability is essential for my business, and I believe it would benefit many other developers in the community as well. The ProblemMy team is building AI solutions in a highly competitive industry where scheduling needs to be seamless and immediate—often over the phone or through automated workflows. Currently, Calendly’s API (as of March 2025) allows us to fetch availability and event details, but there’s no way to directly schedule an event. Instead, we’re forced to send a scheduling link or direct clients to a website to book, which isn’t feasible for our use case. This limitation creates friction:Clients expect instant scheduling during live interactions (e.g., phone calls to our Voice AI agent or via SMS chat with our AI agent). Sending a link or requiring a website visit adds unnecessary ste

Hi When using the customer booking redirect page the following information is passed back to the site from calendy https://xxx/calendy/confirmation?assigned_to=Tyrone&event_type_uuid=2a0df5be-9dd2-4258-8da3-ee9a39749230&event_type_name=30%20Minute%20Meeting&event_start_time=2024-05-31T09%3A00%3A00%2B02%3A00&event_end_time=2024-05-31T09%3A30%3A00%2B02%3A00&invitee_uuid=7a64e37d-b7d6-4f11-9e79-ff924f410e5f&invitee_full_name=Tyrone&invitee_email=xxx@xxx.com&answer_1=Ignore&utm_content=12345%7C678910 How do you get the event information from the above querystring to actually query the API. Calendy send you the invitee UUID, which is useless without the scheduled event ID, and they send you the event type ID, which again is useless for querying a scheduled event.  I cannot find any method in the API where the passed information can be used to query the invitee or the scheduled event since the critical piece of information (scheduled event ID) is not suppl

Hi,Do I have an API to cancel participation of one invitee of a group meeting?I see that cancel API gets only eventId, so If I cancel it, it will be cancelled for all invitees?Thanks.

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

I have used the following code to ensure the cookie banner doesn’t appear:hide_gdpr_banner=1On initial load of the calendar page the banner doesn’t appearBut after someone has booked their first meeting and the calendar allows you to book a second meeting the cookie banner re-appears.How can I stop this from happening?I’m using Divi builder on Wordpress  

I have placed multiple buttons linking to the Calendly Pop-up window script on one Wordpress Elementor built webpage. The first fires the pop-up, but the rest won’t. Is it possible that the browser blocks this because it is already pre-loading the script with the first button? What am I missing here? I re-used the button styling and settings etc.The settings per button are exactly the same.In the test environment I did not install caching plugins etc. and they still act the same as on the live page.I hope someone has the same experience and knows how to solve this.Looking forward to answers.Test: https://cm.miax.nl/dienstenLive: https://cynthiameevis.nl/diensten

Hello,The default Routing response analysis is very nice.  My use case with Routing Forms, however, involves a lot of testing.  I’d like the ability to remove these test responses from the client response analysis.Easy enough to export and clean up the data, but I’d like to be able to simply delete these test responses once a routing form is deployed (or as it gets updated and tested).I see the routing form submission GET endpoints in the API, but no DELETE endpoint.I see no option in the Routing Forms GUI to select and delete responses.Are we NOT able to manage these Routing responses within Calendly at all?Thanks - would be nice to just know one way or the other for certain!

my email is IMAP and  does not work. ANy way to work around it?

I know that the scheduling page can be embedded somewhere else.Is it also possible to embed the “Scheduled Events” view (My Calendly > Scheduled Events)?I would like for our colleagues to have an overview of their scheduled events within a website.

HiI’ve got a facebook meta ad that sends the ad clicker to my calendly booking page.I have meta pixel linked to my calendly booking page.The url at the calendly book page includes a number of parameters, including Fbclid.Upon a successful booking of appointment, the lead then gets redirected to an external thank you page (my website). I have checked the box in calendly to allow for pass through of parameters.However, the most critical parameter Fbclid, does not pass through from calendly to the external thank you page. Requirement:I need to extract the fbclid. What’s the best way to do this? 

Hey folks, how are you?Is it possible to update an event type via API? For instance, I have a webhook that sends me some data, and I would like to modify the event type to a dynamic duration so that when the client schedules an appointment in Calendly, it calculates the time interval and blocks the corresponding time slots.Example: 2 hours and 20 minutes. The client schedules the service at 5 PM, so I would block the calendar from 5 PM to 7:20 PM.

I am struggling to come up with a solution on this.I created a booking page where a customer can choose topics they need help with, each topic has a set duration, so my first issues is I need to dynamically set the event duration. The second issue I have is I have a system knowing which agents are skilled on each topic, so some of the choices may require multiple agents to attend the meeting.I can accomplish both of these issues by creating One-Off Event Types using the API and can do collective events when multiple agents are needed, which is great.The issue I have now is I need to be able to set buffers on these event types, or my agents are going to be bombarded with bookings with no breaks potentially.I really don’t like butting 2 events together as a lot of our sessions do take longer than expected as these are onboarding/support sessions, and we can run into issues if a customer only books a 15 minute topic, and we run into an unexpected issue, which does happen frequently.I also

Hi,We’re setting up the calendly integration but are surprised to see that it doesn’t work without greatly relaxing the Content-Security-Policy in use in our app: in order to work, calendly requires the ‘unsafe-inline' and ‘unsafe-eval’ on both the script-src and style-src fetch directives. This is making us more exposed to CSRF and XSS attacks.So my question is: are you aware of this, and are you planning to update your JS code?Thanks

I successfully used the webhook callback API with signing_key verification a few days ago. But now, for some reason, the signing key changes with every callback making me reject the call.What could possibly be the cause? I did follow the docs @ https://calendly.stoplight.io/docs/api-docs/c1ddc06ce1f1b-create-webhook-subscription Below is my successful webhook I created:    "collection": [        {            "callback_url": "https://TO_SOME_PLACE/",            "created_at": "2023-11-14T18:45:52.610226Z",            "creator": "https://api.calendly.com/users/USER_ID",            "events": [                "invitee.created",                "invitee.canceled",                "invitee_no_show.created"            ],            "organization": "https://api.calendly.com/organizations/ORG_ID",            "retry_started_at": null,            "scope": "user",            "state": "active",            "updated_at": "2023-11-14T18:45:52.610226Z",            "uri": "https://api.calendly.com/webhook_
