FAQ

Questions about Authorize B2 Account.

What does the Authorize B2 Account action do in Backblaze B2?

B2's two-step auth — exchanges the application key for a short-lived (24h) session token used for actual operations. The runtime caches the token, so most workflows don't call this directly; it's mostly for explicit re-auth or for debugging.

What inputs does Authorize B2 Account require?

Authorize B2 Account has no required inputs. Sensible defaults are applied if you leave fields blank.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Backblaze B2 returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Authorize B2 Account support batch operations?

Yes. Run Authorize B2 Account inside a Loop node to process arrays. Tiny Command handles Backblaze B2's rate limits automatically so you don't have to throttle manually.
