Calendly is not connecting to the Outlook calendar I need it to connect with (my business calendar). It says that it's connected (yes, my personal calendar) and will not allow me to add another domain; any suggestions?

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 -->

Zoom Integration not generating meeting link

Hi,I am having an issue with an account’s zoom integration.I did the following test.I go in the Calendly Account and connect the Zoom account for me only.I book a meeting with Zoom as the location.The Zoom link error is displayed in the meetings’ details. I disconnect and reconnect using my personal zoom account, and book another meeting, and it works.When I look at the Zoom activity logs, the API request receives a 400 error, while my personal account goes though no issues.The Zoom account that has issues is part of an organization and has admin access.I am unable to see what the issue might be. Any help is appreciated.

Power Automate HTTP Call to Calendly API Failing with “The access token is invalid”

Hi all,I’m using the Calendly API in a Power Automate flow, specifically the https://api.calendly.com/scheduled_events endpoint inside a HTTP call. As of this morning, the flow is failing with the error below. No changes have been made to the flow or the action in weeks. “The access token is invalid” I’ve already tried generating a new API token, and I can confirm the token works fine when tested in Postman. The issue only seems to occur in Power Automate. Here’s the call structure from my flow:  URI: https://api.calendly.com/scheduled_events Method: GET Headers: Authorization: Bearer <Token> Content-Type: application/json Query Params: Organization: https://api.calendly.com/organizations/<org_id>  Has anyone else run into this issue with Power Automate? Any ideas on why the token would work in Postman but fail inside a flow? Or what’s changed in the last week to make it fail?

How can I make few of the pre-filled fields (like name, email, or custom questions like customer id and brand ) non-editable in the Calendly booking form?

I’m on the Teams plan and using the inline widget. I prefill data like name, email, customer ID, and phone using query parameters in the URL (e.g. ?name=John&email=john@example.com).However, I noticed that even though these fields are pre-filled, the invitee can still edit them before submitting the form. Is there a way to make specific fields read-only or non-editable, especially custom questions like customer id, brand etc? Can I lock email or customer id or brand fields once pre-filled? This is a common need when the customer data is already known and verified. Allowing edits can lead to data mismatches or misuse.Any guidance or workarounds would be appreciated — thank you!

Create an email from Salesforce button

Hi, I am trying to create a custom book an event button in Salesforce, but the information is not carrying over. I followed this article: https://help.calendly.com/hc/en-us/articles/360057224874-How-to-schedule-Calendly-meetings-from-Salesforce#h_01HB9EEWV7K6W791REN257T29Q.  I used the formula:ADD_YOUR_LINK?sfid={!Opportunity.Id}&name={!Contact.FirstName}%20{!Contact.LastName}&email={!Lead.Email}                                      I changed to the Calendly page link. When I click on the button, it redirects me to the scheduling page, but only the first and last name information is carried over. I also need the email address and the mobile number. What am I doing wrong?

bots are ruining my life

Hey guys…my meta ads are somehow getting bots to my page and scheduling calls. I’ve put up a reCAPTCHA wall on my site before anyone can even get on it. Nothing is working. Chat GPT even wrote me a script to prevent calendly from loading until the verification is complete. Nothing. it’s ruining my entire funnel because meta thinks this is a conversion. No matter what I do.Has anyone encountered this?

Forcing calendy oauth consent

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

Connecting Calendly Scheduled Events To Provider Event Id

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?

obtenir un token

Bonjour, j’ai tenté de trouver l’accés pour obtenir mon token afin d’intégrer le calendrier à mon site web et impossible de trouver avant 1h de recherche ( l’enfer). Au bout du compte l’accès m’a été refusé. Je dois dire que la plateforme fonctionne de moins en moins bien avec trop de blocage. cela n’est plus efficient. J’attends votre réponse. Merci beaucoup

Anybody have issues with API calls and "Invitee_Start_Time_Pretty"?

In referencing this API documentation:https://calendly.stoplight.io/docs/api-docs-v1/c2NoOjE4NzA3MzM-webhook-payloadIt says the following: “Human-readable moment when the event starts in invitee's timezone (e.g. "12:00pm - Wednesday, March 14, 2018")”This should mean that the webhook payload data here contains the start time for the invitee, so if this was pulled out of a payload and sent in an email, it wouldn’t be confusing to the invitee regarding what time their meeting is at.Ours, however, ALWAYS sends this in pacific time. We have tested internally with 3 different employees in different time zones and all three have ended up with the invitee start time showing pacific time. Our Calendly is set to mountain time, as well as our Zoho Flow (although this shouldn’t affect anything).What is more interesting, is in the same exact payload, a field titled, “timezone” (the timezone of the invitee) comes across with the correct timezone.Any ideas?

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

Any Updates on Google Business Integration for a Booking Button?

the last response to this was 3 months ago.  I think you’ll find a significant no of people want this. I’ve just had a chat with google AI - you clearly need to prioritise this and don’t understand why it’s not on your roadmap. To assist I’ve received 0 bookings via google business profile. the issue has been illustrated  in earlier questions asking the same thing.

Any support for a test or development environment?

Hi,I’m developing some webhook integrations to consume invitee.* events.We have both a dev and a prod environment and I was wondering if you have any guidelines, best practices, or support for how to set up the dev environment. The goals would be:Have dev and prod share as much as possible - ideally, the only difference would be how they are configured (signing keys, auth keys). Not allow any production data into devThanks!

Unable to Complete Booking via Calendly API After Showing Availability

I have a Calendly Premium account and am using my personal access token to build a customized booking flow.So far, I’ve successfully integrated the external API to: Retrieve and display availability Create a customized calendar UI on my website  The issue is that although availability shows correctly, I cannot complete the booking process through the API.I’ve reviewed the API documentation, but I’m not sure if I’m missing an endpoint, permission, or specific payload structure required for confirming the booking. Could someone guide me on: 1. The correct API flow for completing a booking after retrieving availability.  2. Any special parameters or authentication steps needed for booking confirmation.  3. Whether this is possible with only a personal access token or if I need an OAuth setup.
