I try to test REST api in Postman but every time I try to POST I get the following error

Error: self signed certificate in certificate chain.

I have tried with the SSL certificate verification on and off but both methods dont work. Postman is also updated to latest v7.3.6. Tbh I dont know what to try anymore and would really appreciate any tip.

"make ssl certificate verification on and make it still work"

If you're under organization environment, you can:

  1. Export your organization self-signed certificate as Base-64 encoded X.509 (.CER) format flat file. It could be done from Chrome.
  2. Go back to Postman: Settings -> Certificates -> CA Certificates, switch on and select the file you just exported.
