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."
