Using Signals API

Using the Signals API

Operations for managing and retrieving signals:

• List signals - Get all signals with filtering options

• Get signal by ID - Retrieve a specific signal's details

• Contact research - Deep-dive analysis of individual contacts

• Contact search - Find contacts at companies using LinkedIn Sales Navigator

For creating signals, see the "Creating a Signal" section which includes the recommended synchronous endpoints.

List all signals

get

Retrieve all signals with optional filtering by domain or companyId, pagination and filtering. Results are sorted by creation date (latest first).

Note: For getting completed signal results, we recommend using the /v1/companies/signals/sync endpoint instead, which provides a more efficient cursor-based approach.
