Keep track of changes and upgrades to Harmonic API and bulk data

Written by Harmonic Team

July 27, 2026

GraphQL

  • Adds `notableFollowers` and `numNotableFollowers` fields to `Company` and `Person`

  • Adds `NotableFollower` type with `firm`, `followed`, and `follower` fields

Bulk Data

  • Adds `notable_followers` and `num_notable_followers` columns to `companies` and `people` bulk exports

July 13, 2026

REST

  • Adds notable_followers array to company enrichment responses. Each entry includes follower_urn, follower_name, firm_urn, firm_name, followed_urn, followed_name, and follow_observed_at

  • Adds Notable Followers and New Notable Followers categories to company and person highlights

GraphQL

  • Adds notableFollowers and numNotableFollowers fields to the Company type, backed by the new NotableFollower type

June 22, 2026

REST

  • Adds optional include_fields request property to POST /persons/batchGet

June 8, 2026

GraphQL

  • Adds personFound (Boolean) and enrichmentUrn (String) fields to PersonEnrichmentPayload returned by enrichPersonByIdentifiers. When a person is not yet in Harmonic's database and has been queued for enrichment, the mutation now returns person: null, personFound: false, enrichmentUrn instead of a 404 error. If you currently catch the errors block to detect an unrecognized person or retrieve the enrichment URN, switch to reading personFound and enrichmentUrn from the response body instead.
