**Can I connect more than one Salesforce org?** Not in this version: each tenant has a single Salesforce connection at a time (the "principal" one, Connections tab). **Can I use Production and Sandbox separately?** Not in this version: the connection uses the My Domain URL you pasted (section 4), which points to ONE single environment — Production or a specific Sandbox. To test against a Sandbox first, create your External Client App there and use that Sandbox's My Domain URL; to move to Production, repeat the connection with your real org's data. **The credentials stopped working — what message will I see?** If the credentials are invalid, you'll see *"The token isn't valid; check it and try again"* (code `INTEGRATION_CREDENTIAL_INVALID`). Check the Consumer Key, the Consumer Secret and that the integration user (section 3) is still active, and repeat section 4. **Salesforce isn't responding — what message will I see?** If Salesforce has a temporary incident, you'll see *"The provider isn't available right now. Try again later"* (code `INTEGRATION_PROVIDER_UNAVAILABLE`). **My Salesforce plan doesn't have the API — what happens?** Without REST API access (section 2), the verification in section 4 will always fail, no matter what data you paste. Check with your Salesforce admin whether your plan includes the API add-on, or use a Developer Edition org to test. **Can the agent delete leads in Salesforce?** No. The agent's tools (section 7) only search, look up, create and update — they never delete anything in your Salesforce.
