FAQ
Do I need an Asana workspace?
No. FetchSandbox runs a fully local mock of the Asana API. No workspace, no PAT, no rate limits.
Does it support custom fields?
Yes. Define custom fields, assign them to tasks, and update their values — all stateful across requests.
Can I test webhook handlers?
Yes. Subscribe to events, simulate task changes, and replay events into your handler for signature verification and idempotency tests.
