You have a person
You have criteria, not a person
Search filters such as industries, locations, skills, keywords and technologies take IDs, not free text. Get the IDs from the autocomplete endpoints first.
Typical flows
1
Build a prospect list
Resolve filter IDs with autocomplete, run People search, then look up a work email or phone number only for the people you keep. Guide: Search people by role.
2
Enrich a CRM contact
Start from the LinkedIn handle with Person lookup, or from an email with Reverse email lookup. Guide: Enrich a contact.
3
Enrich thousands of contacts
Use the bulk work email finder with a
webhook_url instead of polling. Guide: Bulk work emails. For whole datasets, a data feed is usually cheaper than the API.
