# DOCUMENTATION

- [Webhooks](https://docs.tryterra.co/vantage-api-docs/documentation/webhooks.md): How Vantage API delivers order and result updates to your endpoint: event families and payloads, HMAC signature verification, and retry semantics.
- [Managing orders](https://docs.tryterra.co/vantage-api-docs/documentation/managing-orders.md): Track orders after placement: fetch full order detail with status history, list and filter orders and results, and curate which products your catalog returns.
- [Test Collection Methods](https://docs.tryterra.co/vantage-api-docs/documentation/test-collection-methods.md): AT\_HOME vs GO\_TO\_LAB orders: which address fields each requires, how lab routing works, and how to find nearby lab draw sites.
- [Results](https://docs.tryterra.co/vantage-api-docs/documentation/results.md): Fetching test results as FHIR documents: the download flow, how to read the Bundle structure, out-of-range and critical values, and failure scenarios.
- [Errors](https://docs.tryterra.co/vantage-api-docs/documentation/errors.md): The error format Vantage API uses (RFC 7807 problem details), what each HTTP status code means, and how to handle validation failures.
- [Monitoring and debugging](https://docs.tryterra.co/vantage-api-docs/documentation/monitoring.md): Observe your integration in production: the analytics overview endpoint, webhook delivery outcomes, and how to debug missed webhooks.
- [Best practices](https://docs.tryterra.co/vantage-api-docs/documentation/best-practices.md): Patterns that keep a Vantage integration robust: webhook handling, deduplication, safe retries, ID handling, and result delivery done right.
