Its Inputs, Outputs, Effects and guards quote the hub’s Waitlist.join; this page adds what each Venue honors, its limits and a worked call. It is one of the Verbs of Forms and waitlists.

Inputs

NameTypeDefaultMeaning
waitlistWaitlistRequiredThe Waitlist to join.
emailemailRequiredWhere to reach the lead.

Outputs

FieldTypeWhat null means
leadLeadNever null: the waiting lead.
waitlistWaitlistNever null: the Waitlist joined.

Effects

Action class

None: no approval rule names it, so it runs within its seat’s Permissions and Limits

Modes
  • try: Runs every check and returns the record as it would be; nothing is stored.
  • send: Returns a pending Action at once; Waitlist.joined fires when it is done.
  • do: Waits for the Action to finish and returns the record.
Idempotency

Only with a key: the same Idempotency-Key and input return the first Action, and the same key with other input returns 409.

Saved or shared

The Waitlist is saved as the call leaves it, with the Action that changed it.

Emits

Waitlist.joined with { waitlist }

Performed by

Whichever seat calls it

Price

Free on your own account: the platform charges nothing for the call.

On each Venue

It acts on your own records and reaches no Venue, so every account answers the same way.

What try does

Runs every check the call meets and returns the record as it would be; nothing is stored, sent or posted.

Refuses when

The hub sets no guard of its own on this call: it refuses only on the shared checks every write meets (a missing record, a Permission the seat lacks).

When it waits

Returns in one response; nothing waits.

Example

In send mode the call returns its pending Action at once, and Waitlist.joined delivers the result.

You, to your agent
Add rosa@northgate-rentals.com to the owner-statements waitlist.
Response, in send mode
{
  "mode": "send",
  "action": {
    "$id": "https://api.sb/leaseline.app/actions/action_Sd3kQ9vT2w",
    "operation": "Waitlist.join",
    "status": "pending",
    "reason": "running"
  }
}

To retry, send the same Idempotency-Key: the retry returns the first answer for $0. A new key reads again.
