What is the difference between Postman and the requests via AppGyver?

Hello AppGyvers,
So far I’ve always done my “REST API direct integration resource” with XANO or Supabase, super easy.

Today I’m trying to make a http request to a webhook url from n8n. I always get the same error here.
Error: TypeError: NetworkError when attempting to fetch resource.status: -1


But the big difference is that one and the same query leads to a positive result at Postmann with the same header information.

My question is what is the real difference between Postman and the requests via AppGyver and how can I close the gap?

Many Thanks

I have seen I can past the url into every browser and get a json response.
So what’s the deal with the error message?
Error: TypeError: NetworkError when attempting to fetch resource.status: -1

I’m sure it can’t be a big deal, I just can’t come up with a solution.
Please I need your help.

Thanks

Bom dia, vc conseguiu resolver o seu problema , estou com o mesmo e nao consigo.
obrigado.

Yes, I could. But the problem lay somewhere else. I was able to use Postman locally because my IP address was shared with Azure. But if I go over an iPaaS solution I had no influence on the IP. Unfortunately, I had to discard the solution.
