Open each Spurvik node and select a **`spurvikApi`** credential with a **Signing Secret** (`>= 16` chars). Add a **Slack Webhook URL** on that credential (and replace `callbackBaseUrl` on node 3 with your own endpoint) before testing the approval branch.\n3. **Optional EU Console Sync**: Set a **Spurvik Console API Key** (`https://console.spurvik.com/signup` — Free €0 for 10k events/mo · Pro €19/mo) on `spurvikApi` to sync hashed receipts and approval events to `fra1`.\n4. **n8n Execution Retention**: Spurvik nodes omit prompt fields from their node output, but n8n saves incoming node inputs on executions by default — set `EXECUTIONS_DATA_SAVE_ON_SUCCESS=none` and `EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS=false` on your n8n instance.",
