My side project osapy.com can be used for testing APIs, webhooks,etc. It doesn't make money yet, but as an indie hacker I would assume it can take a couple of years to get the product right and make any money. Great job on getting 7k EUR!
Very cool. You can also use osapy.com to inspect 3rd party API requests. Or even combine Osapy with endpoints.dev. I wrote a blogpost how to do that for retool.
In which direction do you want to develop the website?
Actually - just tried your website and it doesn't work for me. I tried curl -H "Content-Type: application/json" -d '{"message":"hello world"}' https://8ef216dd46.endpoints.dev and nothing happened. Maybe check your logs.
Are you running behind a load balancer on AWS? You might have to increase the idle connection timeout from the default (60 seconds). I use the max 4000s on hopps.io. Sending keep alive's to prevent the socket connection from closing also helps. Not sure if that's your issue, but worth looking into...
hmm - I can see a few requests have been received & stored for that endpoint.. It could be that your client killed the connection to the websocket api - does refreshing the page show the requests?
I assume the example numbersapi that is loaded by default.
I got the same thing. Leaves me wondering what to do next. It's not clear, then I figured I'll try this curl command, then an error and still nothing obvious to try next.
