API + Webhook Help

I cannot figure out why my request is wrong. My Curl looks like this:curl --request GET \--url 'https://api.calendly.com/scheduled_events?organization=14b0c407-b454-4059-8830-eaf5c92ab325' \--header 'Authorization: Bearer [Here I introduce my personal token, which works in other requests : ) ] \--header 'Content-Type: application/json' But I keep getting “invalid argument” parameter: “organization”. I have no idea what the problem is, since I did a request to find out the organization URI and copy-pasted it as you can see. Any help is appreciated :)

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”.{  "calendar_event": {    "external_id": "",    "kind": "google"  },  "crea

Hello Calendly Developer Community,I'm encountering a critical issue with the "List Events" endpoint in the Calendly API, specifically related to the pagination functionality. I'm hoping to get some insights or assistance from the community.Here's a detailed description of the problem:Initial Request Success: The first API call to the "List Events" endpoint to retrieve 100 events works as expected. Pagination Issue: However, when I attempt to make a subsequent call using the page_token parameter (which I received from the initial request) for the next set of events, the API returns a 400 error. This suggests a problem with the pagination implementation. Environment: I've encountered this issue consistently in both Python and Make (Integromat) environments. Comparison with Other Endpoints: To isolate the problem, I've tested pagination with other endpoints, such as the one used for routing forms, and it worked correctly there. This indicates that the issue seems specific to the "List Ev

Hi,once again a color has been changed within the calendly embed widget. I have a website with a dark background and the text color in the widget is set to bright yellow. However, suddenly the welcome message is displayed in a dark grey, which makes the text barely readable. Could you please look into this asap and fix it?Thank you!

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?

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 -X or --request, GET is already inferred.*   Trying 172.64.146.81:443...* Connected to api.calendly.com (172.64.146.81) port 443 (#0)* ALPN, offering h2* ALPN, offering http/1.1* successfully set certificate verify locations:*  CAfile: /etc/ssl/cert.pem*  CApath: none* (304) (OUT), TLS handshake, Client hello (1):* (304) (IN), TLS handshake, Server hello (2):* (304) (IN), TLS handshak

Is it possible, via the API, to create a single-use scheduling link that also restricts when the invitee can book, e.g., only within a specific date range, only from a certain date onward, or only within the next X days, the same way you can configure this manually in the console?This seems like one of the more compelling use cases for single-use links (controlling exactly when a specific invitee can book), but I can't find a way to set those availability constraints through the API. Am I missing something, or is this genuinely not supported yet?

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!

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!

Hi everyone,My team relies heavily on Calendly for booking our internal syncs, so I am very familiar with the standard routing forms. However, I am currently running into a frustrating frontend issue when trying to embed the booking widget on a custom web app.I recently built a daily HTML5 logic puzzle for my team and our users to take a quick mental break. You can see the mobile layout and play hang five here to understand the UI structure.My goal is to place a Calendly "Inline Embed" directly beneath the main game container so players can easily book a quick feedback call with me. On desktop, the embed works flawlessly. But on mobile viewports (specifically iOS Safari), the invisible container or padding of the Calendly iframe seems to stretch upward and overlap the bottom of my game's CSS grid keyboard. This causes the iframe to "steal" the touch events, meaning players cannot tap the bottom row of letters. Has anyone found a clean CSS wrapper to strictly lock the inline embed's max

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.

Behavior:- Calendly briefly loads, then becomes a blank page.- Happens on desktop and mobile.- Happens across different browsers. URL:https://calendly.com/app/intro/calendar/edit Console error:TypeError: Cannot read properties of undefined (reading 'length') File:intro-4687fcb35.js Additional information:- Network requests appear to load.- Event Types page also becomes blank.

Hi team,I'd like to request Korean (한국어) language support for the Calendly user interface.We plan to use Calendly to schedule meetings with customers and partners in South Korea, and many of them are not comfortable navigating an English-only booking page. Having Korean as a supported UI language would significantly improve the scheduling experience for our Korean-speaking users; both on the booking page side and the internal dashboard.Key areas where Korean support would help: Booking pages shared with external contacts (event descriptions, time selection, confirmation messages) Email notifications and reminders sent to invitees The scheduling workflow (date/time format localized to Korean conventions) Korean is one of the most requested languages in the Asia-Pacific region, and adding support would open up Calendly to a much larger user base and this would help Calendly stay competitive in the market.Would love to hear if this is on the roadmap. Thanks for considering.

Hello,Suddenly our widgets “Submit” buttons are back to the default blue color despite having set custom color “primary_color=202020”. The other custom colors work correctly.Nothing has changed on our end after working perfectly for years. Is this a bug? Is there now a separate code for the buttons?

Hi. I love that you are now offering packages. What would be AMAZING is if one could offer packages with different appointment types. For example, if I offer half-hour check-ins as well as one-hour coaching sessions as options of my appointment types, I would like to offer a large package which includes 6 one-hour sessions and 6 half-hour check-ins for a set rate. so i would be able to bundle several of my services in one offering. i know acuity does this. is there any way calendly can work that out???

Hi Calendly team, Our business has been using your service for a while now, with its integration into Google Calendar / Google Meets.Our employees and clients are very privacy conscious and we want to make the switch from GCal/Meets over to Proton Calendar / Proton Meet for all of our team and customer calls. However currently Calendly does not integrate with them and allow for Calendly bookings to create events in Proton Calendar with a Proton Meet link attached.So, this is a humble feature request to see if you can add support for Proton Calendar / Meets.In addition, if you are aware of a workaround that would let us use Proton Calendar / Meets with Calendly, please let us know. Thanks!

Hi Calendly team,I've run into what appears to be a bug with the Routing Form Logic Builder after the latest update.Issue:When creating or editing a routing form, I go to Logic → Add Route, click "Choose a question", and select one of the form questions. The question is selected, but nothing happens afterward. The next dropdown (where you would normally choose the condition such as "is", "contains", or select an answer) never loads, making it impossible to create routing logic.This workflow worked perfectly before the recent update.I've already tried:Refreshing the page Incognito mode Different browsers Creating a brand new routing formThe behavior is the same every time.I've attached a screenshot showing where the logic builder gets stuck after selecting a question.Is anyone else experiencing this, or is the team aware of the issue? 

Hello,The text of my profile “welcome” message is too light to read on my Squarespace website. I don’t see an option to change the text through Calendly or Squarespace. How can I change the color to make it readable? See below in tan/pink. Would like it to be black. Thanks!  

I’ve had some clients say that they haven’t been receiving the notifications from text messages, but I have it set up for three hours prior to the appointment. Is anyone else experiencing the same problem?

Hi everyone,I’m hoping someone here might have experience with a similar setup.I work at a marketing agency managing performance campaigns that drive users to book test rides at retail locations across Europe. We currently have 80+ locations, each with its own Calendly booking page.We are trying to track marketing attribution using UTM parameters, but we’re running into issues because of the way bookings are triggered from our store locator.Current setup: Ads include UTM parameters (utm_source, utm_medium, utm_campaign, utm_content) User lands on the website The landing page contains a store locator map (StoreRocket plugin) showing test ride locations User selects a store from the map They click “Book Test Ride”, which opens that location’s Calendly booking page Example simplified flow:Ad → Landing page with UTMs → Store locator map → Select store → Open Calendly booking pageThe problem:When the user opens Calendly from the map, the UTM parameters from the original landing page

Hi all,our personal access token never seems to be valid, no matter what we do. We also tested it here through the ressources provided in the developer documentation and received the following message, so we know the issue is rooted here and not on the other side of the token connection (N8N). Has anybody been facing similar issues and found a solution?   

hi everyone i have an AI phone service that allows Calendly to connect their booking platform but i need api key and access token Number. where do i go to add this so my calendar works

Hi everyone,I’m working on a Calendly integration using the API and webhooks, and I want to make sure I fully understand how the webhook system behaves in real-world usage.From the documentation, I understand that Calendly webhooks can be used to trigger events such as:Invitee Created (when a meeting is scheduled) Invitee Canceled (when a meeting is canceled) Routing form submissionsHowever, I’m a bit unclear about a few implementation details in practice:Do webhooks trigger instantly in all cases. or can there be any delay depending on the event type or plan? Are webhook events guaranteed to fire even if no one is actively logged into the Calendly dashboard? If multiple webhook subscriptions exist for the same event type, how is delivery handled? What is the best way to prevent duplicate processing when the same webhook payload is received more than once? Are there any recommended patterns for handling retries or failed webhook deliveries on the client side?I’m building an automation

I’m working on an integration with Calendly and we need to be able to link the Calendly scheduled event to the event in the provider (i.e. Google or MS) as our app also has an integration with our customer’s calendars. What we need is a way to get the provider type and Id for each of the Calendly scheduled events so we can tie them together in our UI.  I see in the APIs documentation for the Event endpoint (https://api.calendly.com/scheduled_events) that it has a property for ‘calendar_event’ but it shows in the API as deprecated  (see: https://developer.calendly.com/api-docs/504508461e486-event ). This field appears to have exactly what we need, but since it’s deprecated, I’m hesitant to use or trust it. Is there a more preferred route to retrieve this data and if not why is this deprecated and how much can we trust it working going forward?

Hi Calendly Support Team,I hope this message finds you well.I am currently integrating Calendly’s OAuth flow into my application, and I would like to ensure that the OAuth consent screen appears every time a user logs in, regardless of whether they have previously authorized the application.As per the documentation and standard OAuth practices, I’ve included the prompt=consent parameter in the authorization URL as shown below:  However, despite this, the consent screen is not being shown consistently. Instead, users are often redirected immediately without being prompted to approve permissions again.Could you please confirm: If prompt=consent is supported by Calendly’s OAuth flow? If there is any additional parameter or setting required to force the consent screen on every authentication attempt? Any guidance or clarification would be greatly appreciated.Best regards,Sammy Abdulrahman
