- Check Make.com scenario logs for any error messages
For n8n authentication issues:
- Verify your server URL is correct (404 errors often indicate an incorrect URL)
- Ensure your request body structure is correct, including the mandatory "provider" field [based on troubleshooting documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1340615317772308520)
- Store your API key in n8n's built-in authentication ("Custom header auth") rather than hardcoding it
## CSV Validation Error: "Phone number is required"
Regarding your CSV validation error, I found several potential solutions:
1. **Check Phone Number Format**: While you mentioned your numbers are formatted as +1XXXXXXXXXX (which is correct), ensure there are no hidden spaces or special characters in your CSV file.
2. **CSV Format Requirements**: According to the documentation, your CSV file should have:
- A required "number" column (for the numbers to call)
- An optional "name" column
- Any other columns from assistantOverridesVapi Support Bot
