Validate the new CloudExport plugin in GIMP 2.10.28 without exposing or using the production API key.
The CloudExport plugin, added in the 2.10.28 release, authenticates via an API key supplied in the gimp-cloudexport.conf file. The default endpoint points to the production service, and the plugin does not provide a built‑in toggle for a sandbox environment.
Production credentials must remain confidential, and the test image must be processed through the same authentication flow that the production workflow uses.

To inject a test API key without modifying the source code, you should target the gimp-cloudexport.conf file located in your GIMP user profile directory. This allows you to use the exact authentication logic as production while directing traffic to a test environment.
gimp~/.config/GIMP/2.10/. On Windows, it is %APPDATA%\GIMP\2.10\. On macOS, it is in ~/Library/Application Support/GIMP/2.10/.gimp-cloudexport.conf file within the plug-ins or root profile folder (depending on the specific plugin installation).api_key value with your test credential.endpoint_url to point to your sandbox URL.The recommended approach to isolate traffic while using the same authentication mechanism is to use environment variables, if the plugin script supports them. If the plugin hard-codes the production URL, the gimp-cloudexport.conf file is your only point of intervention.
To verify if the plugin accepts environment-based overrides, try launching GIMP from the terminal with the variable set:
export CLOUDEXPORT_API_KEY="test_key_here" gimp
endpoint_url override within the .conf file. If not, the plugin will attempt to hit the production endpoint regardless of the key.Diagnostic Question: Does your current gimp-cloudexport.conf file contain an endpoint or url key, or is it limited to the API key field?
Use comments to ask for clarification. Post a solution as an answer.

To ensure that the gimp-cloudexport.conf modifications are functioning as expected without risking production data, it is useful to verify the API endpoint and test credentials outside of the GIMP environment first.
Because GIMP 2.10.28 plugins typically rely on Python 2.7 for internal bindings, network requests may behave differently than in modern Python 3 environments. You can verify the sandbox connectivity by running a minimal Python 2.7 script that mimics the plugin's request structure:
import urllib2
url = "https://your-sandbox-endpoint.com/export"
headers = {'Authorization': 'Bearer test_key_here'}
request = urllib2.Request(url, headers=headers)
try:
response = urllib2.urlopen(request)
print "Connection Successful: %s" % response.read()
except Exception as e:
print "Connection Failed: %s" % e
If the standalone script fails but the production key works, the issue likely lies with the sandbox firewall or the specific Python 2.7 SSL/TLS implementation used by GIMP 2.10, rather than the configuration file path.
