Steps
Register an application in the Trimble Developer Console to obtain OAuth client credentials
Complete the OAuth 2.0 authorization flow against Trimble Identity to get a user-context access token (developer.trimble.com/docs/connect/guides/access/)
Call the Core API to list projects/folders, e.g., GET app.connect.trimble.com/tc/api/2.0/projects with the bearer token
Upload or download survey deliverables (point clouds, CAD files) via the project's file resource endpoints
Use the Topics API alongside Core if you need to push BCF-compatible field issues/RFIs tied to the same project
Known gotchas
Requires a full OAuth app registration and user consent flow, not a simple static API key — adds setup overhead for a one-off script
Access tokens are user-context and expire; production integrations need refresh-token handling, not a single long-lived key
API version paths (e.g., 2.0) have changed across Trimble Connect releases; check the current Core API reference before hardcoding endpoint versions
