Watchlists

Watchlists let you group companies, persons, addresses, properties, and vehicles into named lists and receive notifications when monitored entities change.

Overview

Concept	Meaning

Members	Entities (companies, persons, addresses, properties, vehicles) added to a watchlist.
Subscriptions	Event types the watchlist is tracking - without a subscription, no events are recorded.
Notifications	Destinations (webhook / email / SMS) that receive events for a watchlist.
Events	Changes detected on members, delivered to every enabled notification.

Watchlist CRUD

List watchlists

curl -H "x-api-key: YOUR_API_KEY" \
  "https://lens-api.tic.io/watchlists?sortBy=name"

Query parameters:

Parameter	Type	Default	Description
`sortBy`	string	`name`	`name` or `created`

Response - array of watchlist objects:

[
  {
    "watchListGuid": "a1b2c3d4-e5f6-...",
    "watchListName": "My companies",
    "watchListDescription": "Portfolio monitoring",
    "numberOfCompanies": 42,
    "numberOfPersons": 0,
    "numberOfNotifications": 2,
    "numberOfSubscriptions": 5,
    "numberOfUnacknowledgedEvents": 3
  }
]

Create a watchlist

curl -X POST "https://lens-api.tic.io/watchlists" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "watchListName": "My companies", "watchListDescription": "Portfolio monitoring" }'

Field	Type	Required	Constraints
`watchListName`	string	Yes	1–200 characters
`watchListDescription`	string	No	Max 1000 characters

Returns 201 Created with the full watchlist object and a Location header.

Update a watchlist

PUT /watchlists/{watchlistGuid}

Same request body as create. Returns the updated watchlist.

Delete a watchlist

DELETE /watchlists/{watchlistGuid}

Returns 204 No Content. Deleting a watchlist removes all members, events, notifications, and subscriptions.

Members

Each member type has the same three operations: list (paginated), add, and remove.

Adding a member

# Add a company
curl -X POST "https://lens-api.tic.io/watchlists/{watchlistGuid}/companies/3508351" \
  -H "x-api-key: YOUR_API_KEY"

Replace companies/3508351 with the entity type and ID:

Entity	Route	ID field
Company	`/companies/{companyId}`	`companyId`
Person	`/persons/{personId}`	`personId`
Address	`/addresses/{addressId}`	`addressId`
Property	`/properties/{propertyId}`	`propertyId`
Vehicle	`/vehicles/{vehicleId}`	`vehicleId`

Returns 201 Created with the member GUID:

{
  "watchListMemberGuid": "f6e5d4c3-b2a1-...",
  "companyId": 3508351
}

Returns 409 Conflict if the entity is already a member.

Listing members (paginated)

Member lists use the same offset-based pagination as other table endpoints. See Pagination for the full reference.

curl -X POST "https://lens-api.tic.io/watchlists/{watchlistGuid}/companies" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "startRow": 0, "endRow": 50 }'

Paginated member endpoints:

Endpoint	Description
`POST /watchlists/{id}/companies`	Company members
`POST /watchlists/{id}/persons`	Person members
`POST /watchlists/{id}/addresses`	Address members
`POST /watchlists/{id}/properties`	Property members
`POST /watchlists/{id}/vehicles`	Vehicle members

Exporting members

Each member type can be exported as CSV:

GET /watchlists/{watchlistGuid}/companies/export
GET /watchlists/{watchlistGuid}/persons/export
GET /watchlists/{watchlistGuid}/addresses/export
GET /watchlists/{watchlistGuid}/properties/export
GET /watchlists/{watchlistGuid}/vehicles/export

Removing a member

DELETE /watchlists/{watchlistGuid}/members/{memberGuid}

Returns 204 No Content. Associated events are also deleted.

Moving members

Move a single member to another watchlist:

curl -X POST "https://lens-api.tic.io/watchlists/{watchlistGuid}/members/{memberGuid}/move" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "targetWatchListGuid": "b2c3d4e5-f6a7-..." }'

Move multiple members at once:

curl -X POST "https://lens-api.tic.io/watchlists/{watchlistGuid}/members/move" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "targetWatchListGuid": "b2c3d4e5-f6a7-...",
    "memberGuids": ["f6e5d4c3-b2a1-...", "a1b2c3d4-e5f6-..."]
  }'

Returns 409 for members that already exist in the target watchlist. Bulk move reports skipped duplicates:

{
  "movedCount": 8,
  "skippedDuplicates": ["f6e5d4c3-b2a1-..."],
  "targetWatchListGuid": "b2c3d4e5-f6a7-..."
}

Check membership

Find which watchlists an entity belongs to:

curl -H "x-api-key: YOUR_API_KEY" \
  "https://lens-api.tic.io/watchlists/membership?companyId=3508351"

Pass exactly one query parameter: companyId, personId, addressId, propertyId, or vehicleId.

Event subscriptions

Subscriptions control which event types generate events for a watchlist. Without subscriptions, no events are recorded.

List subscriptions

curl -H "x-api-key: YOUR_API_KEY" \
  "https://lens-api.tic.io/watchlists/{watchlistGuid}/subscriptions"

Response:

[
  {
    "subscriptionId": "abcdef01-2345-...",
    "eventType": 1,
    "eventTypeName": "CompanyAddress",
    "lastUpdatedAtUtc": "2025-03-15T10:30:00Z"
  }
]

Subscribe to a single event type:

curl -X POST "https://lens-api.tic.io/watchlists/{watchlistGuid}/subscriptions" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "eventType": 1 }'

Subscribe to all event types at once:

curl -X POST "https://lens-api.tic.io/watchlists/{watchlistGuid}/subscriptions" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "subscribeToAll": true }'

Unsubscribe

DELETE /watchlists/{watchlistGuid}/subscriptions/{subscriptionId}

Event types

Value	Name	Entity
1	`CompanyAddress`	Company
2	`CompanyName`	Company
3	`CompanyStatus`	Company
4	`CompanyRegistration`	Company
5	`CompanyIntelligence`	Company
6	`CompanyBeneficialOwner`	Company
7	`CompanyDocument`	Company
8	`CompanyWorkplace`	Company
9	`CompanyPerson`	Company
10	`CompanyRegisteredOffice`	Company
11	`CompanyShareCapital`	Company
12	`CompanyPurpose`	Company
13	`CompanyDebtBalance`	Company
14	`CompanyOrderToPayCase`	Company
15	`CompanyFinancialDocument`	Company
16	`CompanyCase`	Company
17	`CompanyWorkplaceAddress`	Company
25	`PersonAddress`	Person
26	`PersonName`	Person
27	`PersonIntelligence`	Person
28	`PersonStatus`	Person
29	`PersonCompany`	Person
40	`PropertyOwnershipChange`	Property
41	`PropertyMortgageDeedChange`	Property
47	`VehicleOwnerChange`	Vehicle
48	`VehicleUserChange`	Vehicle
49	`VehicleStatusChange`	Vehicle
50	`VehicleInspection`	Vehicle
51	`VehicleStolen`	Vehicle
57	`ResidentMovedIn`	Address
58	`ResidentMovedOut`	Address

ResidentMovedIn and ResidentMovedOut report that someone has registered as living at a watched address, or has moved away from it or been deregistered. A move between apartments at the same address does not count. The events carry no personal data, and people with protected personal data never produce them.

Notifications

Notifications define where events are delivered. Each watchlist can have multiple notification destinations.

List notifications

curl -H "x-api-key: YOUR_API_KEY" \
  "https://lens-api.tic.io/watchlists/{watchlistGuid}/notifications"

Response:

  {
    "notificationId": "12345678-abcd-...",
    "destination": "https://example.com/webhook",

    "destinationTypeDescription": "Webhook",
    "hasBeenValidated": true,
    "lastUpdatedAtUtc": "2025-03-15T10:30:00Z"
  }
]

Create a notification

Test a webhook notification

POST /watchlists/{watchlistGuid}/notifications/{notificationId}/test

Sends one sample event to the webhook and returns the payload. See Webhooks & notifications for the payload format.

Events

When a subscribed change is detected on a member, an event is recorded. Events persist until the member is removed.
