I have a server in a supermarket that has an N8N installed on it. Basically it works like this:
The bubble sends a get to an n8n webhook api with a parameter called query that inside it has a query for a database from that supermarket.
n8n receives this get, takes the query and searches directly in their postgresql database, takes the result and does a respond to webhook to show all the information that was searched in the database in the result when I do the get in the bubble.
But I have a problem, they have a firewall on their network, that is, it doesn’t recognize anything that is coming internally, for example if I test it inside the supermarket with their network through postman, I can get it safely. But if I test using bubble it doesn’t even recognize the API IP.
Would anyone have a solution for supermarket staff to do but that isn’t too risky for their safety?
I saw about localtunnel ngrok but I don’t know how it works, if they are the solution tell me here!!
