**Can I connect more than one PandaDoc account?**
 Not in this version: each tenant has a single PandaDoc connection at a time (the "principal" one, Connections tab).

**The key stopped working — what message will I see?**
 If the key is invalid or was revoked in PandaDoc, both when connecting and on "Test connection" you'll see *"The token isn't valid; check it and try again"* (code `INTEGRATION_CREDENTIAL_INVALID`). Generate a new key in PandaDoc (section 3) and repeat section 4.

**PandaDoc isn't responding — what message will I see?**
 If PandaDoc has a one-off incident, you'll see *"The provider isn't available right now. Try again later"* (code `INTEGRATION_PROVIDER_UNAVAILABLE`) — it's not a problem with your key, try again in a few minutes.

**The agent tried to send a document with no approved template — what happens?**
 The tool refuses: it only operates on a document already generated from a DocGen template with signing configured (Manual 18). Without that, the agent has nothing to send.

**Can I use the Sandbox key instead of the Production one?**
 Not for real use: the Sandbox key adds a watermark to documents and limits recipients to your own domain — it's useful for testing the mechanism, never for signing with real customers.
