Waitlist allows form creators to control submissions dynamically based on rollup field conditions — perfect for managing limited capacity (e.g., event attendee caps).
🔧 Key Capabilities:
Conditional Activation:
Example: If
RSVP Count >= 3, waitlist is triggered.
Redirect Handling:
Redirects submitters to another form or an external page (e.g., a waitlist page on your website).
Dynamic Evaluation:
Condition checked every time the form is accessed — ensures real-time enforcement.
Auto-Reopen:
If an attendee cancels (e.g.,
RSVP = Cancelled), rollup field updates automatically, and the form becomes available again.
📝 How to Enable Waitlist:
1️⃣ Go to Form Settings:
Open form → Settings → Enable Waitlist.
2️⃣ Set Condition:
Example:
RSVP Count >= 3.Select a relevant rollup field and comparator (e.g.,
>=).
3️⃣ Set Redirect URL:
Specify destination URL (another form, a waitlist list, or an external webpage).
4️⃣ Publish Changes:
Waitlist will trigger immediately once the condition is met.
⚠️ Important Considerations:
Concurrency edge cases:
If several users submit forms around the threshold simultaneously:
First valid submission is accepted.
Others are shown a validation message:
“Submission limit reached. You will now be redirected.”
Then redirect occurs as configured.
Field Availability:
Ensure that the form includes all fields needed for the rollup condition (e.g., RSVP option must exist for RSVP-based conditions).
✅ Example Use Case:
Event RSVP with Capacity Limit
Limit attendees to 20.
Create a roll up field on your list based on the condition
RSVP = YesAs soon as
RSVP Count >= 20:Form redirects to waitlist form or information page.
If someone cancels:
Form reopens automatically for more submissions.
