Accessing the SAAS Rest APIs through a corporate Proxy - curl command

[Ashley.Lewis]

Can someone assist with the command to access the Rest APIs of the SAAS controller using curl command? I want to do this through the corporate proxy

This is what I have so far but I am facing an Authentication 401 Unauthorized Error

curl -v --proxy http://proxyusername:password@proxyaddress:proxyport --user username@account:password https://SAASURL/controller/rest/applications

Is there something I am missing?

The username@account:password is working outside the corporate proxy.

Hi @Ashley.Lewis,

I found a few existing Community posts that seem related. Please have a look and let me know if they help.

401 unauthorized in Rest Api and REST API access 401 error

Hi Ryan,

Thank you for the response. Those posts did not help actually.

I am already using a locally created account and I am able to successfully call the API outside the Corporate Proxy using this user.

The second post also points to the account being improper which is not the problem in my case as I get it to successfuly work outside the Proxy.

Hi @Ashley.Lewis,

Thanks for letting me know. Let's see if the Community can jump in and offer a solution or workaround. If I find any posts or info, I will share it here as a reply.

Hi Ashley

When you do a curl test to the AppDynamics URL using the proxy what response do you get?

curl -I -x <proxy hostname>:<proxy port> --proxy-user username:password https://<appd fqdn>.saas.appdynamics.com

And also what proxy server are you using , nginx, squid?

Ciao

These are the outputs that I get

I'm not sure about the proxy that is in place in the organization. Is that supposed to make a difference to the behavior?

[Ashley.Lewis · Accepted solution]

I was able to get this to work by using the curl command with a header token instead of passing the username and password using an api client user. It looks like it is potentially a problem of the proxy not passing the parameters of username and password on to AppDynamics SAAS.
