Can the assistant change my bookkeeping in Yuki?

Only one thing: booking a general journal entry, and by default that waits for a person’s approval in the browser (your workspace’s rules decide). Everything else only reads. Contacts, invoices and document uploads are not offered.

Does every call count against Yuki’s daily limit?

Yes. Yuki allows a domain 1,000 free web service calls a day, and each tool call signs in first, so a call costs two of them, three when it also looks up the only administration.

Does GitHub Copilot see the password or key for Yuki?

No. The key for Yuki is pasted into Flowplane once and kept sealed there. GitHub Copilot only gets a Flowplane sign-in for you, which you can revoke in the console.

Can GitHub Copilot change things in Yuki without asking?

Not by default: every change in Yuki waits for your approval in the browser. Your workspace’s rules decide, per tool.

1
Add Yuki in Flowplane
In the Flowplane console, add Yuki and paste the web service access key.
Yuki’s bookkeeping API works with a web service access key, not a personal login. A domain administrator creates the key in Yuki (Settings, Web services), chooses which services it may use and for which administrations, and pastes it into Flowplane once. Flowplane keeps it sealed; the assistant never sees it.
