New Event Type Management APIs

Hey developers! We’re excited to share that we’ve released a new set of APIs that let you create, update, and configure one-on-one event types, directly within your own interface.These endpoints are ideal for embedding the Calendly setup experience (with limited event type configuration) into your app or platform, so you can enable users to set up Event Types and streamline the onboarding experience.New endpoints:Create a new Event Type:POST /event_types Update an existing Event Type:PATCH /event_types/{uuid} List Event Type availability schedules:GET /event_type_availability_schedules Update Event Type availability schedules:PATCH /event_type_availability_schedules List user meeting locations:GET /locationNote: the Create/Update Event Type endpoints support one-on-one Event Types only, and are limited to basic field configuration (owner, title, description, duration, duration options, locations, visibility, color, locale). LinkedIn Premium Business used these APIs to power a new Calen

Swedish holidays

I noticed that only a limited number of countries are available for “Holiday schedule”. I’m happy to provide the dates for Swedish holidays (these are established by the government) in any useful format.  Even though Sweden might not be the largest country, the holiday days are mostly the same in all Scandinavian/Nordic countries, so hopefully it’s of use to many users.

Help!. I am not receiving https://calendly.com/scheduled_events/

After a Calendly booking via Typeform, I only receive the invitee ID, but I need the event UUID for API purposes. How can I get the event UUID?

Custom Calendly Integration for Shopware 6 Webshop – Need API Guidance

Hi everyone,we're currently working on integrating Calendly into our Shopware 6 webshop, but unfortunately the standard plugin doesn’t meet our requirements – so we plan to build a custom plugin ourselves.Our goal:We want to offer installation appointment slots through Calendly, with different time blocks based on how long the service takes. For example: 3-hour installation 6-hour installation Customers should be able to choose the appropriate appointment type directly from our webshop.Questions we need help with: Where do we start with the Calendly API integration into Shopware? Do we need an API key to interact with Calendly? Is a Calendly developer account required, or is this possible with a standard paid account? How do we handle appointment types with different durations and availability? Has anyone here already worked on a Shopware 6 x Calendly integration? Any pointers, API setup guides, or code references would be greatly appreciated. We’re happy to share our progres

400 error, invalid parameter on "organization" yet "organization" is required

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.

Feature Suggestion - customizable field names for url parameters

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.

Need to add Buffer when creating a one--off event type via API

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

Make Watch Events Module Not Working

We’ve set up a simple automation using Make and the Calendly Watch Events module, but it appears to have a bug.The module claims to receive cancellation events, but after thorough testing on our end, we’ve confirmed that it does not. Regular scheduled appointments are received as expected.Could you please review this and let us know how long a fix might take? We’re relying heavily on this, and it’s currently breaking our workflow.Calendly Watch Events Module in a Make scenario

In the embed form, the text and bg color in the expandable details override my color settings.

This is the first time I’ve used Calendly and I was disappointed in the customization options for the embed form. I was able to choose background, text, and link colors. However I chose a darker theme and there are details in the second step that aren’t adhering to those settings. I would remove the details if I could. It’s an expanding toggle, which should have less prominence. Because the background and text css has been overridden, it has much more prominence than it should. I can’t change these settings on my end. Essentially, there are two css properties that are creating the issue, which I believe should be removed..c1y2smo4 { background-color: var(--coreColorNeutral100, #fafafa); color: var(--coreColorNeutral900, #0a2540);}If I turn these off, everything looks fine (see images). Is there a way this can be corrected on the Calendly side?Link to page: https://sensryui.com/contact/Properties turned off, shows my preferred styles

New Feature Request - Customizable Query Code Autofills

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.

Calendly + JIRA Integration (formatting date/time) - Need Help!

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?

Hide Event Type Details

I’ve tried using hide_event_type_details=1 to remove the event type details from an inline embedded form. My goal is to eliminate the unnecessary step of making someone click a single listed event type just to select a date and time. How do I accomplish this? <!-- Calendly inline widget begin --><div class="calendly-inline-widget" data-url="https://calendly.com/connect-xyzcorp?hide_landing_page_details=1&hide_gdpr_banner=1&hide_event_type_details=1" style="min-width:320px;height:100vh;"></div><script type="text/javascript" src="https://assets.calendly.com/assets/external/widget.js" async></script><!-- Calendly inline widget end -->

Pending Scheduled Events and Creating Meeting Polls via API

Hello,I'm currently working on integrating Calendly more deeply into our scheduling workflow and have several questions regarding the API's capabilities, specifically around scheduled events and meeting polls. Querying Pending Events: Is there a way to specifically query for scheduled events that are in a 'pending' state, such as meeting polls? This functionality would be incredibly useful for managing large numbers of appointment requests. Creating Meeting Polls via API: While the API documentation provides details on creating One-Off Event Types, I am curious if there is a similar capability for creating meeting polls. I noticed that the event type class includes a pooling_type attribute. Could this be utilized to create meeting polls, and if so, could you provide some guidance or point me to the relevant documentation? I appreciate any help or direction you can provide. Thank you for supporting the community with your insights!

Request: API Endpoint to GET Poll Responses

 I’m reaching out to request a critical feature for Calendly’s API: an endpoint to get/retrieve poll data. 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 workflows in the financial industry where meetings need to be seamless and easy -- often requiring our internal users to leverage multiple systems to schedule, log, and execute the meeting. Currently, Calendly’s API (as of 29-Apr-2025) does NOT allow us to fetch meeting poll results, so there is no way to determine which events are ready to be scheduled across hundreds of scheduled meetings. This limitation causes friction:Clients expect instant scheduling once availability is confirmed. Scrolling through hundreds of meetings and emails to determine which are ready for scheduling takes significant time, leading to drop-offs and lost business. In competitive markets, delays in scheduling can result in clients choosing faster alt

Identify Event name

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!
