Steps
Register on the HCSS Developer Portal and follow the 'Getting Started with Request Tokens' guide to obtain an access token
Use the HeavyBid Pre-Construction API to list/query Estimates, then drill into Biditems, Activities, and Resources for a given estimate
Use the separate HeavyBid Estimate Insights API for aggregate/analytics endpoints if summarized reporting is needed instead of row-level data
Test endpoints with the portal's downloadable API spec in Postman or Insomnia before building an integration
Known gotchas
Access requires an active HCSS/HeavyBid customer account — this is a customer-scoped integration API, not an open public dataset
Pre-Construction and Estimate Insights are separate API products with different endpoints/scopes; confirm which one exposes a given bid-item field before assuming coverage
