Steps
Trigger a run with an authenticated POST to https://app.getcensus.com/api/v1/syncs/{sync_id}/trigger, sending an empty body — the response includes a sync_run_id to track it.
Authenticate using the bearer/API token format shown in Census's docs (a personal or service API key issued from the Census workspace).
Poll for status using the sync runs listing endpoint, filtering to the run just triggered (e.g. requesting a small per_page and taking the most recent entry) rather than assuming a single-run GET endpoint exists.
Treat the status field on each sync run as the source of truth for success/failure/in-progress, and only consider the sync complete once it reaches a terminal status.
Cross-reference docs.getcensus.com (triggering workflow) with developers.getcensus.com (API reference) for exact request/response shapes.
Known gotchas
Don't assume a singular GET /sync_runs/{run_id} endpoint exists just because a run ID comes back from the trigger call — the confirmed pattern is listing sync runs and filtering, so build polling logic around that.
Triggering a sync with an empty POST body means no one-off overrides can be passed in that call — any per-run customization needs to be configured on the sync beforehand, not injected at trigger time.
