In its **Vrymdor token** step, paste the full URL from your Vrymdor dashboard into **URL**. It already ends in /v1/token. (Dashboard: **AI agents**, **Connect your AI Node**, **n8n Cloud**, **URL for the Vrymdor token step**.)\n2. In the same step, **Custom Auth**, **Create new credential**. In its JSON field paste **Vrymdor token credential (Custom Auth JSON)** from the same card. It is filled in with your Agent ID and Agent Secret and looks like:\n`{\"body\": {\"agent_id\": \"agt_...\", \"agent_secret\": \"vrym_agent_...\"}}`\nThen **Save**. The secret stays in the credential: it is not shown in the workflow and does not leave with it when you share or export it.\n3. Check the connection: **Execute step** on **Vrymdor token** shows an `access_token`. 404 means the URL is missing /v1/token or has the wrong node address: paste the full URL from your dashboard again. 401 or “Authorization failed” means the Agent ID or Agent Secret is wrong: copy both again. 502 means your node is off: turn it on in Home base and copy the URL fresh.\n4. **Execute workflow**. The output shows `[REDACTED:EMAIL]` and `[REDACTED:CREDIT_CARD]`, and `vrymdor.redactions` counts them.\n\nReplace **Sample text** with your own trigger (set `items_from` in **Vrymdor AI Node** to its name).
