Actions

All 12 actions, with every field they accept and every variable they return.

Each action's outputs are available to later steps as {{action_key.field}} — so Create Meeting's join link is {{zwa_create_meeting.joinUrl}}. The key under each heading is the one to use.

Blank is not the same as empty on any update action. The workflow builder sends every field on every run, including the ones you left alone, so a blank box means "leave this as it is" rather than "clear it". The exceptions are called out where they exist.

Create Meeting

Schedule a Zoom meeting from a workflow.

zwa_create_meeting

Fields

Field	Type	Required	What it does
`topic`	text	yes	The meeting title. Merge fields are rendered before it reaches us.
`startTime`	text	yes	Parsed leniently, so an appointment merge field can be dropped in as-is with no formatting step in between.
`duration`	number	no · 30	Minutes, up to 1440.
`timezone`	text	no	An IANA name such as Europe/Lisbon. Zoom's account default when blank.
`agenda`	text	no	The description Zoom shows on the meeting.
`password`	text	no	Up to 10 characters. Zoom generates one when blank.
`hostVideo`	toggle	no · on	Host camera on entry.
`participantVideo`	toggle	no · on	Attendee cameras on entry.
`waitingRoom`	toggle	no · on	Hold arrivals until the host admits them.
`enableRegistration`	toggle	no · off	Turn registration on, which is what makes personal join links and attributable attendance possible.
`manualApproval`	toggle	no · off	Hold registrations for screening instead of issuing links immediately. Ignored unless registration is on.
`appointmentId`	text	no	Map {{appointment.id}}. Without it, attendance writeback has to find the booking by searching the contact's appointments and matching on start time.

Returns

Variable	Type	What it is
`meetingId`	text	Zoom's numeric id, as a string — it exceeds what a number can hold exactly.
`joinUrl`	text	The link to send a contact.
`startUrl`	text	The host's start link. Whoever opens it starts the meeting as host.
`password`	text	The meeting passcode.
`topic`	text	As created.
`startTime`	text	As created.
`duration`	number	Minutes.
`timezone`	text	As created.
`registrationEnabled`	true/false	Whether registration is on.
`quotaRemaining`	number	What Zoom's rate-limit header reported, or -1 when it said nothing. Not the 100-a-day create cap.
`deduplicated`	true/false	True when a repeated request returned the meeting that already existed.

Worth knowing

startUrl is a credential, not a link. It embeds a token with a measured lifetime of two hours, and anyone holding it within that window takes the host seat — mute, remove, record, admit from the waiting room. Never send it to a contact. It sits next to joinUrl in the variable picker and the two names look interchangeable in a dropdown, which is exactly how the mistake gets made.
startUrl is returned once, on creation, and never re-served. A retry that dedupes to an existing meeting gets an empty string rather than the credential again.
quotaRemaining reads like the daily cap and is not. Zoom exposes no header for the real 100-a-day limit; this one reports a rate-limit category window and has been observed returning 399, a number the cap cannot produce.

Get Meeting

Read a meeting's current state mid-workflow.

zwa_get_meeting

Fields

Field	Type	Required	What it does
`meetingId`	text	yes	A numeric id, not a join link. Spaces are stripped, so a value copied from Zoom's interface works.

Returns

Variable	Type	What it is
`meetingId`	text	As requested.
`topic`	text	Current title.
`agenda`	text	Current description.
`startTime`	text	Current start.
`duration`	number	Minutes.
`timezone`	text	Current timezone.
`joinUrl`	text	The attendee link.
`password`	text	The passcode.
`status`	text	Zoom's own word: waiting or started.
`hostEmail`	text	Which Zoom user hosts it.
`registrationEnabled`	true/false	Whether registration is on.
`createdByThisApp`	true/false	True when this app created it and holds the CRM correlation.

Worth knowing

There is no 'ended' status. Zoom reports a finished meeting as waiting again, indistinguishable from one that never ran, which is why attendance comes from the Meeting Ended trigger rather than from polling this.

Update Meeting

Change the time, topic or settings of a meeting already scheduled.

zwa_update_meeting

Fields

Field	Type	Required	What it does
`meetingId`	text	yes	The meeting to change.
`topic`	text	no	Left alone when blank.
`startTime`	text	no	Parsed leniently, as on Create Meeting.
`duration`	number	no	Minutes, up to 1440.
`timezone`	text	no	Left alone when blank.
`agenda`	text	no	Left alone when blank.
`password`	text	no	Left alone when blank.
`hostVideo`	toggle	no	Always applied. See the note below.
`participantVideo`	toggle	no	Always applied.
`waitingRoom`	toggle	no	Always applied.
`manualApproval`	select	no · unchanged	Switch between automatic and manual approval, or leave approval as it is. Only reaches Zoom when registration is already on.

Returns

Variable	Type	What it is
…		Everything Get Meeting returns, describing the meeting after the change.
`quotaRemaining`	number	Same caveat as on Create Meeting.

Worth knowing

Blank means 'leave it alone', not 'clear it'. Zoom's update replaces what it receives, so sending an empty agenda because the workflow left the box empty would erase the agenda written at creation. Every text field here is skipped when blank.
The three toggles are the exception, and it is worth reading twice. A toggle has no 'leave alone' state, so a step that only means to move the start time also applies whatever the video and waiting-room toggles happen to show. Set them to what the meeting should end up with, not to what you are changing.
An update spends the same daily allowance as a creation. The cap is 100 create or update calls per Zoom user per day, so a workflow that reschedules on every reply can exhaust it without creating a single meeting.

Delete Meeting

Cancel a meeting and tell whoever registered.

zwa_delete_meeting

Fields

Field	Type	Required	What it does
`meetingId`	text	yes	The meeting to cancel.
`notifyRegistrants`	toggle	no · on	Email everyone registered that it is cancelled.
`notifyHost`	toggle	no · off	Email the host too. Off, because the workflow's owner already knows.

Returns

Variable	Type	What it is
`meetingId`	text	As requested.
`deleted`	true/false	Whether the call removed it.
`alreadyGone`	true/false	True when the meeting was not there to begin with.

Worth knowing

alreadyGone is not an error. A workflow that re-runs, or a host who cancelled in Zoom first, both land here, and 'the meeting is not there' is the outcome the step asked for either way.
Notifying registrants defaults to on deliberately. Someone holding a personal join link for a meeting that no longer exists otherwise finds out by turning up to nothing.

Add Registrant

zwa_add_registrant A Licensed Zoom plan

Fields

Field	Type	Required	What it does
`meetingId`	text	no	Usually left blank. When empty, the contact's current meeting is resolved from our own records. Supply it only to register someone for a meeting that is not their latest.
`email`	text	yes	Zoom validates this. Map {{contact.email}}.
`firstName`	text	no · empty	Zoom requires a first name, but a contact without one is an ordinary CRM record, so this is defaulted rather than rejected.
`lastName`	text	no	Up to 64 characters.
`phone`	text	no	Shown to the host on the registration.
`org`	text	no	Company or organisation.
`jobTitle`	text	no	Job title.
`city`	text	no	City.
`state`	text	no	State or region.
`country`	text	no	Two-letter country code. Zoom rejects anything else.
`zip`	text	no	Postal code.
`comments`	text	no	Free text shown to the host alongside the registration.
`autoApprove`	toggle	no · on	Approve immediately. On a manual-approval meeting a pending registrant gets no join link at all.

Returns

Variable	Type	What it is
`joinUrl`	text	This person's personal link. The field the step exists to produce.
`registrantId`	text	Zoom's id for the registration.
`meetingId`	text	The meeting they were registered for.
`topic`	text	The meeting title.
`startTime`	text	When it starts.
`email`	text	As registered.
`approved`	true/false	False when the meeting is on manual approval and the link is still pending.
`alreadyRegistered`	true/false	True when this email was already registered and the original link was returned.

Worth knowing

Do not map Create Meeting's meetingId into this step. GoHighLevel renders one marketplace action's output into another's input as an empty string, so the mapping silently produces nothing. Leaving the box blank is the supported path, and it resolves the contact's meeting from our own records.
Registration is what turns attendance from a guess into a fact. Without it every attendee shares one link and Zoom reports them by whatever name they typed, so participantEmail arrives empty and a call cannot be tied to a person.
A personal link belongs to one contact. Sending the same one to two people makes both of them the same attendee in every later report.

Get Registrant

Look up whether someone is registered, and whether they are approved.

zwa_get_registrant

Fields

Field	Type	Required	What it does
`meetingId`	text	yes	The meeting to search.
`email`	text	yes	Keyed on email, not on Zoom's registrant id — a workflow asking 'is this contact registered' has an email and nothing else.
`status`	select	no · approved	approved, pending or denied. Search pending to find someone waiting on a manual-approval meeting.

Returns

Variable	Type	What it is
`found`	true/false	Whether a registration was found. Branch on this.
`registrantId`	text	Zoom's id, when found.
`email`	text	As found.
`firstName`	text	As registered.
`lastName`	text	As registered.
`status`	text	approved, pending or denied. Empty when not found.
`joinUrl`	text	Their personal link. Empty while pending — Zoom issues it on approval.
`meetingId`	text	As requested.

Worth knowing

Zoom's list defaults to approved registrations only, so leaving status alone reports a pending registrant as not registered — the exact case someone checking registration status usually cares about most.
This also finds people who registered through Zoom's own page rather than through a workflow.

Update Registrant Status

Approve, deny or cancel a registration without leaving the workflow.

zwa_update_registrant_status

Fields

Field	Type	Required	What it does
`meetingId`	text	yes	The meeting.
`email`	text	yes	Who to act on.
`action`	select	no · approve	approve issues the link; deny refuses a pending registration; cancel revokes an approved one and invalidates the link Zoom already emailed.

Returns

Variable	Type	What it is
`meetingId`	text	As requested.
`email`	text	As requested.
`action`	text	What was asked for.
`applied`	true/false	Whether it took effect.
`joinUrl`	text	The link, after approving. Empty on deny and cancel, where there is deliberately no link to hand out.
`warning`	text	Empty when it worked; a sentence otherwise.

Worth knowing

Approving is what issues the join link. A pending registrant has none until this runs, so a workflow that emails the link straight after Add Registrant on a manual-approval meeting sends an empty one.

Update Attendance

Mark the booking showed or no-show from what actually happened on the call.

zwa_update_attendance

Fields

Field	Type	Required	What it does
`meetingId`	text	yes	Map {{zwa_meeting_ended.meetingId}}. The only required field — everything else is resolved from our own record of creating the meeting.
`status`	select	no · auto	auto decides from attendance. The explicit values are new, confirmed, cancelled, showed, noshow and invalid.
`minimumMinutes`	number	no · 1	Minutes of attendance required to count as showed, in auto mode. Raise it to filter out the attendee who dials in, sees an empty room and leaves.
`appointmentId`	text	no	Overrides appointment resolution. Rarely needed.
`showedTags`	text	no	Comma-separated tags to add to the contact when they attended.
`noshowTags`	text	no	Comma-separated tags to add when they did not.
`skipAppointmentUpdate`	toggle	no · off	Apply tags only and leave the appointment alone, for customers driving their calendar from elsewhere.

Returns

Variable	Type	What it is
`status`	text	The status written, or the one that would have been.
`attended`	true/false	Whether anyone joined.
`attendedMinutes`	number	The longest single attendance.
`attendeeCount`	number	Distinct people who joined.
`actualMinutes`	number	How long the meeting ran.
`appointmentId`	text	The appointment written to, or empty when none was found.
`appointmentUpdated`	true/false	Whether the calendar write happened.
`appointmentSource`	text	How the appointment was found: provided, recorded, matched, or none.
`contactId`	text	The contact.
`tagsAdded`	text	Comma-separated tags actually applied.
`warning`	text	Empty when everything worked; otherwise a sentence explaining what did not.

Worth knowing

minimumMinutes measures the longest single attendance, not the sum across people. Two people staying twenty minutes each is a twenty-minute meeting, not forty.
This step returns success with a warning rather than failing. A workflow step that errors stops the whole run, and 'we could not find the appointment' should not stop the follow-up email going out. Branch on appointmentUpdated if you want to know.
auto is the default because the honest answer is the one Zoom already gave. The explicit statuses exist for workflows with their own idea of an outcome — a discovery call that ran four minutes is a no-show to one agency and a win to another.

Create Webinar

Schedule a Zoom webinar from a workflow.

zwa_create_webinar A paid plan with the webinar add-on

Fields

Field	Type	Required	What it does
`topic`	text	yes	The webinar title.
`startTime`	text	yes	Parsed leniently, as on Create Meeting.
`duration`	number	no · 60	Minutes, up to 1440. Longer default than a meeting.
`timezone`	text	no	Account default when blank.
`agenda`	text	no	The description.
`password`	text	no	Up to 10 characters.
`enableRegistration`	toggle	no · on	The opposite default to a meeting. Registration is the point of the format and what makes attendance attributable.
`practiceSession`	toggle	no · off	Attendees join muted and hidden.
`appointmentId`	text	no	Map {{appointment.id}}, same as Create Meeting.

Returns

Variable	Type	What it is
`webinarId`	text	A different id space from meetings — a webinar id is not a meeting id.
`joinUrl`	text	The attendee link.
`startUrl`	text	The host's start link. The same credential, with the same rules, as on Create Meeting.
`password`	text	The passcode.
`topic`	text	As created.
`startTime`	text	As created.
`duration`	number	Minutes.
`timezone`	text	As created.
`registrationEnabled`	true/false	Whether registration is on.
`quotaRemaining`	number	Same caveat as on Create Meeting.
`deduplicated`	true/false	True when a repeat returned the original.

Worth knowing

Deliberately narrower than Create Meeting. Panelists, polls, Q&A and practice sessions are real webinar features and are configured once in Zoom rather than re-specified on every workflow run.
startUrl deserves a sharper warning here than on a meeting: a webinar has a registration page and an audience holding personal links, so whoever takes the host seat does it in front of everyone who signed up.

Update Webinar

Reschedule or edit a webinar.

zwa_update_webinar A paid plan with the webinar add-on

Fields

Field	Type	Required	What it does
`webinarId`	text	yes	The webinar to change.
`topic`	text	no	Left alone when blank.
`startTime`	text	no	Left alone when blank.
`duration`	number	no	Minutes, up to 1440.
`timezone`	text	no	Left alone when blank.
`agenda`	text	no	Left alone when blank.
`password`	text	no	Left alone when blank.
`practiceSession`	select	no · unchanged	A select rather than a toggle, so it has a genuine 'leave it alone'.

Returns

Variable	Type	What it is
`webinarId`	text	As requested.
`topic`	text	After the change.
`agenda`	text	After the change.
`startTime`	text	After the change.
`duration`	number	Minutes.
`timezone`	text	After the change.
`joinUrl`	text	The attendee link.
`registrationUrl`	text	The public sign-up page.
`password`	text	The passcode.
`hostEmail`	text	Which Zoom user hosts it.
`registrationEnabled`	true/false	Whether registration is on.
`createdByThisApp`	true/false	Whether this app created it.
`quotaRemaining`	number	Same caveat as elsewhere.

Worth knowing

Worth more care than the meeting equivalent despite being nearly the same fields. Moving a meeting inconveniences one contact; moving a webinar affects everyone registered, and there may be hundreds of them.

Delete Webinar

Cancel a webinar and tell everyone registered.

zwa_delete_webinar A paid plan with the webinar add-on

Fields

Field	Type	Required	What it does
`webinarId`	text	yes	The webinar to cancel.
`notifyRegistrants`	toggle	no · on	Email everyone registered.

Returns

Variable	Type	What it is
`webinarId`	text	As requested.
`deleted`	true/false	Whether the call removed it.
`alreadyGone`	true/false	True when it was not there to begin with.

Add Webinar Registrant

Sign a contact up for a webinar and hand them their own link.

zwa_add_webinar_registrant A paid plan with the webinar add-on

Fields

Field	Type	Required	What it does
`webinarId`	text	yes	Required here, unlike on Add Registrant — webinars and meetings share no id space.
`email`	text	yes	Zoom validates this. Map {{contact.email}}.
`firstName`	text	no · empty	Zoom requires a first name, but a contact without one is an ordinary CRM record, so this is defaulted rather than rejected.
`lastName`	text	no	Up to 64 characters.
`phone`	text	no	Shown to the host on the registration.
`org`	text	no	Company or organisation.
`jobTitle`	text	no	Job title.
`city`	text	no	City.
`state`	text	no	State or region.
`country`	text	no	Two-letter country code. Zoom rejects anything else.
`zip`	text	no	Postal code.
`comments`	text	no	Free text shown to the host alongside the registration.

Returns

Variable	Type	What it is
`joinUrl`	text	This person's personal link.
`registrantId`	text	Zoom's id for the registration.
`webinarId`	text	As requested.
`topic`	text	The webinar title.
`startTime`	text	When it starts.
`email`	text	As registered.
`alreadyRegistered`	true/false	True when this email was already signed up.

Worth knowing

This mirrors Add Registrant field for field against the webinar endpoint. They are two actions rather than one with a toggle, so a wrong id fails visibly in the workflow rather than quietly inside ours.
