Bug: The mutation quick start example is broken. It uses getApiUrl without importing it and references an out-of-scope variable organization.slug instead of the correct orgSlug.
_{Severity: LOW}

Suggested Fix

Import getApiUrl from its source file. In the call to getApiUrl, replace the reference to the out-of-scope variable organization.slug with the correct parameter, orgSlug.

Potential issue: The mutation quick start code example in the documentation contains two
errors that prevent it from functioning. First, it calls the `getApiUrl` function
without including the necessary import statement. Second, it references
`organization.slug` to construct the API URL path, but the `organization` variable is
not in scope. The intended variable is `orgSlug`, which is available as a parameter to
the mutation function but is not used. These issues will cause immediate TypeScript or
runtime errors for any developer attempting to use this code example.
