Unable to install plugin via HTTP API

  • What Grafana version and what operating system are you using?
    Grafana: 11.1.0
    Environment: Podman container
    OS: Fedora 40 x86_64

  • What are you trying to achieve?
    I am trying to install a plugin via HTTP API using admin service account

  • How are you trying to achieve it?
    Call API endpoint:
    URL: http://localhost:3001/api/plugins/esnet-arcdiagram-panel/install
    Authentication: Bearer [REDACTED]
    Body:

{
	"version": "1.0.4"
}
  • What happened?
    API returned 403:
{
	"accessErrorId": "ACE5310255672",
	"message": "You'll need additional permissions to perform this action. Permissions needed: plugins:install",
	"title": "Access denied"
}
  • What did you expect to happen?
    API returned 200 with some data and plugin installed

  • Can you describe the configuration(s) that you are having problems with?
    Service account has admin privileges and API is working fine with dashboards/datasources/etc

  • Did you follow any online instructions? If so, what is the URL?
    I used endpoint and response format from grafana-client · PyPI library

can you point out grafana documentation that shows this install plugin api endpoint?

I think this part of API is undocumented. Despite this it exists and can be called. As well as the endpoint for getting all plugins, it works properly.

So it can be working differently between different versions.

I think Grafana UI uses that as well, so check endpoint/payload generater by your UI in the browser console.

But your problem seems to be an authorization. I would use “super admin” account, which works only with basic auth usually.

what are we looking at here @sowdenraymond doesnt seem like grafana docu to me?

its the pypi doc not official Grafana
