"content": "# Public Webhook Relay\n## How it Works\nUtilizes webhook.site to receive public webhook requests and relays them to your local n8n workflow\n\n## How to Use\n- To use with local key-value store:\n Go to settings > community nodes and enter ```@horka.tv\/n8n-nodes-storage-kv``` to install the key-value store node\n- To use with a different storage method:\n Replace the four key-value nodes with a temporary storage option of your choice (Airtable, Notion, Firebase, etc). This is required to save data between runs.\n- Set **Schedule Trigger** with a polling interval (default is every 10 seconds).\n- Set your local workflow address in Local Webhook Address.\n\n## How to Test\n- Set the workflow to *Active*.\n- After workflow executes at least once, you can check the input to **Get Latest Requests** for your auth token.\n- Run this command: ```curl -X POST -H \"Content-Type: application\/json\" -d '{\"foo\":\"bar\"}' https:\/\/webhook.site\/[THE AUTH TOKEN YOU JUST GOT]```\n- Now check **Executions** and confirm that the workflow ran all the way to the end. Confirm in **Unprocessed Requests** that your data was retrieved (data[0].content should be equal to {\"foo\":\"bar\"})\n- Now check your other local workflow and confirm that it was triggered with the correct data packet ```{\"foo\":\"bar\"}```.\n- *You're done!*\n\n## Caveats\nAt present, the relay expects a POST with form\/json data. If you wish to relay raw data or GET requests, please alter the **Unprocessed Requests** and **POST to n8n** nodes accordingly."
