API + Webhook Help

Bonjour, Je m’explique, j’aimerai laisser un choix réduit du type de rendez-vous sur des plages occasionnelles, par exemple de décider d’accepter que des rendez-vous visio sur une matinée, occasionnellement 

Is there a way to dynamically create landing pages with multiple event types that allow me to programmatically append unique utm tracking terms to the link urls? I need a unique landing page for each of my customers. 

Does Calendly API support updating a user's default availability schedule directly?

Hi Calendly Community,I’m integrating Calendly webhooks with a Shopify store to automate booking confirmations (~100 bookings/day). Webhooks are set up, but some events fail to trigger.Setup: Calendly Premium, Shopify API, Zapier for automation.Steps Tried:Verified webhook URL and secret in Calendly. Tested Zapier triggers; some events miss. Checked logs, no clear error codes.Questions:What’s the best way to debug Calendly webhook failures? Any common issues with Shopify-Zapier-Calendly integrations? Tips for ensuring reliable webhook triggers?Thanks for your insights!

I am building a react application where I will have Two Main Organisations ( for usecase ). Each user should be a host to create interviews with the members under that particular User. For Creating interviews, I need custom durations where I will have a form to enter date, start time and end time. After submitting this, Can this be sent to calendly to add the invitees under this organisation ( User ) and generate an interview.Also I want to list interviews, Cancel and reschedule them, all should be one organisation Specific.Is this possible in Calendly, if so what plan should I get and what steps Should I follow ?

We have used Calendly in the past on other projects and was a fan of their Popup Text popup. It was nicely contained and styled, compared to other platforms. We just switched over to Calendly for another project and were disappointed to see their styles got updated in the last couple of days and now this popup shows an off-putting scrollbar, with half the content cut off. Is this a bug or is this the expected result now? This is what the popup used to look like just a few days ago:  This is what the popup looks like now (Per the demo page):

Why can’t other members of my team see my Product Demos being booked in our Slack? The Calendly integration only works on an individual basis, and only I can see when product demos are booked for myself. I want my engineers to be able to see when product demos are booked in Slack as well, since they like to see the notification when it comes in.

Dear Calendly Support,I am reporting a recurring issue that is significantly impacting my ability to use your platform. For the past several days, I have encountered the following problems: Booking Error: When attempting to schedule appointments, I receive a persistent error message stating, “Oops, something went wrong.” Client-Side Issues: Clients have also reported being unable to schedule appointments and are receiving similar errors. PayPal Integration: There are ongoing issues with PayPal payments not processing correctly. I have attempted to disconnect and reconnect my PayPal account, but the issue persists. These errors are interrupting business operations and client scheduling. Please advise if Calendly is experiencing outages or technical issues on your end. I would also appreciate being notified of any known service disruptions in the futur

I asked this 9 days ago but never got clarity on which field I am supposed to use.If I do this:curl --request GET \  --url "https://api.calendly.com/scheduled_events?organization=https://api.calendly.com/organizations/DERERCVFDYL7OLC&min_start_time=2025-01-01T00:00:00Z&max_start_time=2025-06-30T23:59:59Z" \  --header 'Authorization: Bearer eyJraWQiOiIxY2UxZTEzNjE3ZGNmNzY2YjNjZWJjY2Y4ZGM1YmFmYThhNjVlNjg0MDIzZjdjMzJiZTgzNDliMjM4MDEzNWI0IiwidHlwIjoiUEFUIiwiYWxnIjoiRVMyNTYifQ.eyJpc3MiOiJodHRwczovL2F1dGguY2FsZW5kbHkuY29tIi234523zUtYmQxMy03ZTBhNWIwNDk2MjciLCJ1c2VyX3V1aWQiOiJBSEhCWE5MVElEQVJMWkU3In0.jsvcK0mRkCdIF87BJ7UxVaHfQDWClDc-QEIl-PyYuXYVm95wDIWR4r-_Xw7IwLp_18Q-amd8BGmsa5deb0P9qw' \  --header 'Content-Type: application/json' There is no field called “UUID”. But I’m supposed to use a UUID if I then call the API for “invitees”.  Again, this is the JSON that comes back. It does not have a field called “uuid”.

If I go here: https://developer.calendly.com/api-docs/6rb6dtdln74sy-list-groups It says:“Query Parametersorganization, string, required, Return groups that are associated with the organization associated with this URI” The words “query parameters” normally mean a parameter that is in the URL, after a question mark, therefore I try: curl -vvv  --request GET --url "https://api.calendly.com/groups?organization=DCF*******7OLC" --header 'Authorization: Bearer {hidden}' --header 'Content-Type: application/json' But I get a 400 error. Since I’m using the -vvv flag, the full response is:  Note: Unnecessary use of

Hi there Does anyone know how to retrieve a Calendly UUID, based on an invitee URL through Calendly’s APIs? For context, I am using the Typeform / Calendly integration with Make. The URL captured in Typeform doesn’t appear to include UUID information.  Any help will be appreciated! ThanksRhys   

Hi all,I’m working on an API integration for a website, and even though (for now) it’s working correctly, I’m wondering if I’m there’s a better way to get a user availability for an event type to display in a calendar component.Since `event_type_available_times` has a 7-day date range limit, I’m currently doing 4 consecutive calls to fetch the availability for each month. The problem is that it’s incredibly slow, so when the user first opens up the calendar, or then switches to the next month, it’s taking around 5-7 seconds to complete all the requests and display the days with availability.Is there a more optimized/faster way to do this? Thank you!

I am using calendly trial version. As I have multiple user in my organization account I cant fetch scheduled events through API. I am using personal token.

I’m attempting to find all of the “Shared Event Types” in my organization (the ones whose edit URLs look like https://calendly.com/organization_event_types/<id>/edit ); it appears that none of them are returned through the list user's event types endpoint when invoked with an organization ID. If I invoke the list endpoint with an individual user ID instead of the organization ID, I can find them, but it’s not particularly efficient to iterate through all of my users and separately enumerate their event types. Is there some extra undocumented flag I can pass to

Wouldn’t it be great if the Calendly API allowed you to send a time range (a start time and an end time) and then receive a response indicating whether that time slot is available? I envision an API endpoint where you send a new appointment request with a specified start and end time, and Calendly returns:• Whether that time slot is available for scheduling, and• If available, the option to create a new meeting/appointment directly via the API. This feature would make it much easier to integrate Calendly into automated workflows and scheduling systems by allowing us to quickly check availability and then book appointments if the slot is free. Looking forward to feedback and discussions on this idea!

i want to ask question why when i insert the code in my website in the first image look like this and how to make look like the second one  

I have a use case where I want to partner with local restaurants and offer a Book A Table feature via my app. Is there a way I can use a single ‘master’ API key to access the individual calendars of my partner restaurants and create bookings via the API? 

I am trying to create an automation. When a person book a time in my Event page, I sent this information to Albato, an automation tool. As I have 2 event pages, one called Interview and the other Strategy Session. Which variable should I use to identify the Event name? Even though I am using the Event variable as you can see the image, it is not working. So, I believe this is not the correct variable to be using. The name is correct but the Event this not to be the correct variable.Does anyone know which variable is the correct one to be used to identify the Event Page?Thank you! 

We just migrated to Calendly API v2 and are having issues with formatting the date/time fields.In particular, I’m using the start_time api field. There is no more “pretty” version of the start_time api field, so we need to format it in JIRA automation. I noticed, we get the date/time value in the start_time field as “2025-06-25T05:00:00.000000Z” (for example). However, in the JIRA documentation, JIRA is expecting the date/time field as “2020-08-18T02:40:37.0+0000” (for example). Because of this, the smart value format operations in JIRA automation do not recognize the date/time format therefore will not work. Has anyone found a solution to this issue?

We advertise the link to our Calendly on another website (which we have no control over). When a person clicks on this link, certain query codes are attached to the link.It would be extremely helpful if we could use this information to autofill the answers to some of our questions when the person is signing up for a time slot.

When prefilling Calendly forms, the url parameters codes are not customizable (i.e., first name is first_name, custom question 1 is a1).  It would be great if we could set the url field code dynamically for integration with vendors who push data in a set format (yes, requested the opposite with those vendors as well).  For instance, instead of using “a1” as the field parameter, allow user to change it to a custom name.

Good day,I have created a new SAML certificate in Entra and I am trying to figure out the best method to update it in the Calendly Admin center or if a brand-new connection to have to be established? I could not find an article on this so I was wondering if anyone would know the answer to this or if anyone knows how to get ahold of technical support, the chat option is not available for some reason. Thanks! 

Hello Calendly Community, I’m reaching out for guidance on three specific challenges I’m currently facing:  Multilingual Support My website operates in four languages (EN, FR, DE, IT), and I’d like to use a single Calendly booking form to handle all requests, while adapting the experience to the visitor’s language. Hidden Fields for Tracking I would like to pass hidden parameters in the booking URL (such as language and source/channel) and capture them with each booking. This would help us identify where the booking originated (e.g. homepage, blog, pricing page). Host Notifications with Hidden Field Data Ideally, the host receiving the booking should see those hidden parameters in the email notification, to better prepare for the call.   Could anyone share how they’ve approached this setup—or if it’s
