Lead Lists can be used to upload a set of leads which will then undergo additional enrichment and processing in order to reveal as much information on each lead as possible, leveraging Amplemarket’s vast database. Usually the flow for this is:
  1. POST /lead-lists/ with a list of LinkedIn URLs that will be processed and revealed
  2. In the response, follow the URL provided in response._links.self.href
  3. Continue polling the endpoint while respecting the Retry-After HTTP Header
  4. When validation completes, the results are in response.results
  5. If the results are larger than the default limit, then follow the URL provided in response._links.next.href
