List HRIS Providers
Returns the distinct HRIS/payroll providers across the same book GET /v1/employers returns, sorted for display. Use these as the values for the employers list’s hris_provider filter — filter on provider, show provider_label. The stored providers are free text, so they cannot be enumerated in advance.
Authentication
API Key or Access Token authentication using Bearer token in Authorization header. API keys use the vit_apk_ prefix, access tokens use the vit_at_ prefix.
Headers
Organization to act as for this request (e.g. org_SGVsbG8gV29ybGQ). Optional when your credentials reach a single organization. Required when they reach several — omitting it then returns 400 organization_required. A malformed value returns 400 invalid_organization_header, and naming an organization you do not have access to returns 403 organization_access_denied.
Response headers
Unix timestamp (seconds) when the rate limit window resets
