Calendly

Sync scheduling events, invitees, availability schedules, and audit activity from Calendly into your data warehouse.

Authentication

The Calendly connector uses OAuth 2.0 with PKCE (Proof Key for Code Exchange, S256 method). Weld initiates the OAuth flow and exchanges an authorization code for access and refresh tokens on your behalf. No manual token management is required.

Available Streams

All streams run as full syncs — the entire dataset is re-fetched on every sync run. Incremental syncing is not currently supported for any Calendly stream.

Stream	Table Name	Primary Key	Sync Mode	Requires Enterprise
List Events	list_events	uri	Full	No
List Event Invitees	list_event_invitees	uri	Full	No
List User Availability Schedules	list_user_availability_schedules	uri	Full	No
List Activity Log Entries	list_activity_log_entries	uri	Full	Yes

List Events

Fetches all scheduled events for the authenticated user, ordered by start_time ascending.

Endpoint: GET /scheduled_events

Column	Type	Description
uri	string	Unique resource identifier for the event
name	string	Event name
status	string	active or canceled
start_time	string	ISO 8601 start time
end_time	string	ISO 8601 end time
event_type	string	URI of the event type definition
location	object	Location details (type, join URL, etc.)
invitees_counter	object	Total, active, and limit counts

List Event Invitees

Fetches all invitees across every scheduled event for the authenticated user. Weld first paginates through all events, then fetches invitees per event.

Endpoint: GET /scheduled_events/{event_uuid}/invitees

Column	Type	Description
uri	string	Unique resource identifier for the invitee
email	string	Invitee email address
name	string	Invitee display name
status	string	active or canceled
timezone	string	Invitee's timezone
event	string	URI of the parent event
rescheduled	boolean	Whether the invitee rescheduled
old_invitee	string	URI of the previous invitee record before rescheduling
new_invitee	string	URI of the new invitee record after rescheduling
cancel_url	string	URL for the invitee to cancel
reschedule_url	string	URL for the invitee to reschedule
scheduling_method	string	How the event was scheduled
invitee_scheduled_by	string	Who booked on behalf of the invitee
text_reminder_number	string	Phone number used for SMS reminders
routing_form_submission	string	URI of the routing form submission, if applicable
questions_and_answers	array	Intake form responses
tracking	object	UTM and attribution tracking data
payment	object	Payment details, if payments are enabled
no_show	object	No-show marker details
reconfirmation	object	Reconfirmation status and timestamp
created_at	string	ISO 8601 creation timestamp
updated_at	string	ISO 8601 last-updated timestamp

---

List User Availability Schedules

Fetches all availability schedules configured by the authenticated user.

Endpoint: GET /user_availability_schedules

Column	Type	Description
uri	string	Unique resource identifier for the schedule
name	string	Display name of the schedule
user	string	URI of the owning user
timezone	string	Timezone the schedule rules apply to
default	boolean	Whether this is the user's default schedule
rules	array	Array of availability rules (days, intervals)

---

List Activity Log Entries

Requires Calendly Enterprise plan. This stream will fail with a permissions error if the authenticated user's organization is on a Standard or Teams plan.

Fetches the organization-wide audit log, ordered by occurred_at ascending. Useful for compliance reporting and auditing user actions across the organization.

Endpoint: GET /activity_log_entries

Column	Type	Description
uri	string	Unique resource identifier for the log entry
occurred_at	string	ISO 8601 timestamp of when the action occurred
namespace	string	Category of the action (e.g. event_type, user)
action	string	The specific action taken (e.g. created, deleted)
fully_qualified_name	string	Namespaced action name (e.g. event_type.created)
organization	string	URI of the organization the entry belongs to
actor	object	Who performed the action (URI, display name, type)
details	object	Additional context about the action

Known Limitations

No incremental syncs

All four streams use full sync mode only. Every sync run re-fetches the complete dataset from Calendly's API. For accounts with large event histories this can result in long sync durations and higher API usage. Incremental sync support is not currently implemented.

Invitees sync performance scales with event volume

The list_event_invitees stream fetches invitees by iterating over every event returned by list_events and making a separate API call per event. For accounts with thousands of historical events, this results in a large number of sequential API requests and significantly longer sync times.

Scoped to the authenticated user only

The connector authenticates as an individual Calendly user. Streams like list_events and list_user_availability_schedules are scoped to that user's data only — they do not return organization-wide data across all team members. To sync data for multiple users, separate connections would be needed per user.

The list_activity_log_entries stream is the exception: it is scoped to the entire organization, which is why it requires an Enterprise plan.

Activity log requires Enterprise

The list_activity_log_entries stream requires a Calendly Enterprise subscription. Attempting to sync this stream on a Standard or Teams plan will result in a 403 Forbidden error from the Calendly API, and the sync job will fail.
