What Handoff does and does not do
Handoff stores the request, routes a delivery, validates the answer, and records the receipt. It does not capture a stack, resume your process, or pretend that an email/SMS provider is included. Your code may wait with a blocking call, webhook, or poll, then apply the answer.Where to go next
- Quickstart — run the first request.
- The protocol — read the wire model and signing rules.
- SDKs — install from the repository and use Python or TypeScript.
- Conformance — run the compatibility suite locally.
