Create a self-hosted blockchain payment processor with x402 and 1Shot API
UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This workflow has 18 nodes and runs when an HTTP POST request hits its webhook URL (plus 2 other triggers). Along the way it connects 1shot (community).
How it runs
Trigger: When an HTTP POST request hits its webhook URL (plus 2 other triggers).
- Check POST Payload (If): checks a condition and branches into true / false
- Supported Networks Config (Code): runs custom JavaScript code
- Lookup Payment Configs & Split Signature (Code): runs custom JavaScript code
- Bad Payload (If): checks a condition and branches into true / false
- Response: Return Supported Networks (Respond to Webhook): sends the response back to the webhook caller
- verify or settle (If): checks a condition and branches into true / false
- Unsupported Token (If): checks a condition and branches into true / false
- Response: Bad POST Body (/verify) (Respond to Webhook): sends the response back to the webhook caller
- Response: Bad POST Body (/settle) (Respond to Webhook): sends the response back to the webhook caller
- Simulate Payment (One Shot): simulate
…plus 5 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 2 community packages, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-1shot is verified or supports 3.0 (used in Simulate Payment).
- Check that n8n-nodes-1shot is verified or supports 3.0 (used in 1Shot API Submit & Wait).
