Install App Exchange apps into Sandbox when you are not Administrator of production org.
To install Appexchange packages you need : “Download AppExchange Packages” permission on your profile.
you could either ask your admin to give you that permission on sandbox or modify the profile to give you that access if you have the permission to do that (which you maybe should not if you're a delegated admin).
You can install packages to a sandbox, when you click the get it now button on the appexchange, you can select to install in your sandbox.
hope this helps ! :)
Our developers have Download AppExchange Packages on their SANDBOX Org profile, not in the Production org profile. AppExchange login ONLY allows login via your Production (login.salesforce.com) profile. Basically, there is no way for sandbox only system admins to download and install AppExchange packages in sandbox only if they are not System Admins in our Production org. Are you saying that you need Download App Exchange on your production org profile even if its just for sandbox testing?
You can login to even a devloper ORG credentials and when you click get it now , you are presented with the options
You can select the Sandbox option and then use those credentials ..
hope this helps !
As Mentioned earlier, you still need download packages permission in your profile in sandbox.
Good approach. Proabably all the same, but seems slightly cleaner when looking to just play in the sandbox alone....
One other thing that caused me issues: I am running a pi-hole, and it was blocking api.appexchange.salesforce.com, so if you're using a pi-hole, you should add that to your whitelist.
