Prospects Overview
The Prospects API provides endpoints for managing potential tenants and their preferences throughout the leasing process.
Key Concepts
Prospect Information
Prospects contain essential contact and preference information:
- Contact Details: Name, email, and phone information
- Property Association: Each prospect is linked to a specific property
- Referral Tracking: Source of how the prospect found the property
Prospect Preferences
Prospects can specify their housing preferences:
- Unit Requirements: Number of bedrooms, bathrooms, and half-bathrooms
- Pricing Range: Minimum and maximum price preferences
- Lease Terms: Preferred lease duration
- Move-in Timeline: Desired move-in date range
- Additional Notes: Other specific requirements
Primary Prospect
Every prospect carries isPrimaryProspect, which mirrors the Primary marker Fortress shows on a
household member. It is read from the application the prospect was converted into, so it is tri-state:
isPrimaryProspect is filterable like any other boolean field: isPrimaryProspect = true,
isPrimaryProspect = false, or isPrimaryProspect = NULL for the undetermined records. Each value
is available on both the list and read endpoints below.
An undetermined prospect is returned without the isPrimaryProspect key rather than with a
literal null — the export pipeline omits null columns, as it does for every nullable field on this
API. Treat a missing key as null; isPrimaryProspect = NULL matches those records.
isPrimaryProspect reflects the application household, not the prospect record itself. A prospect
that has never converted is the only person on its own record, but that does not make it true here —
the value stays undetermined until a conversion creates the household the marker lives on.
Prospect Statuses
ProspectStatus is fixed, platform-wide master data — the same 14 statuses with the
same ids exist in every environment, and the catalogue has no organizationId or propertyId. Fetch it via the list endpoint below and send the returned id as
prospectStatusId when updating a prospect’s status.
Prospect Updates
Available by RequestProspect contact information and preferences can be updated after creation via a partial update — only the fields supplied in the request body are modified. A prospect’s leasing status can also be updated independently via a dedicated status endpoint.
This endpoint is part of our evolving API ecosystem. To explore availability for your integration, please contact our team.
Prospect Leslie Integration Configuration
Available by RequestA prospect’s Leslie integration configuration reports whether Leslie is enabled for that prospect. If no configuration has been saved yet, the endpoint returns enabled: true and effectiveEnabled: true. Integrations should use effectiveEnabled, which accounts for a disabled quiet period that has elapsed.

Portal Invitations
Available by RequestEvery prospect can be sent their own resident portal link to register and start an application.
POST /prospects/{prospectId}/portal-invitation returns it, creating the prospect’s portal account
if they do not have one yet. Once an account exists, the same link is also returned as
portalInviteUrl on the prospect records from the list and read endpoints.
The portal-invitation endpoint also returns the login link, without creating an account, when the
prospect’s email address already has a claimed account at the property on another record, such as
their application. A claim link is only ever returned for an account under the prospect’s own email
address. The endpoint returns 400 and changes nothing when Leslie is not enabled for the property,
when the prospect has no claimed account and no usable email address (missing or a placeholder such
as none@none.com), when another record already holds a pending invitation for that email at the
property, or when the property blocked the prospect’s portal account.
Fortress does not send anything when you request the link — delivering it is up to you.
The claim link lets whoever holds it set the prospect’s portal password. Send it only to the prospect it belongs to.
