Treat a secret as a server responsibility
If a provider issues a secret API key, do not place it in browser JavaScript, public configuration or a downloadable mobile bundle. Users can inspect client software. A typical design sends the visitor’s request to your backend, which validates it and calls the provider using a server-held credential.
Separate storage from permission
Storing the key securely does not make an endpoint safe by itself. If anyone can submit unlimited requests, they may still consume your paid service through that endpoint. Decide who may use it, limit input size and enforce appropriate usage controls. Do not rely on hiding the URL or checking the page’s visible form.
Build a narrow endpoint
For an AI idea builder, accept only the fields the feature needs. Keep the model choice and provider credentials on the server. Reject malformed input before making a paid request. Return the generated result or a useful error, never the key or a raw provider response containing unnecessary operational details.
Keep environments distinct
Use separate credentials where practical for development and production. Record who owns each credential and how it can be replaced. Avoid writing secrets into logs, screenshots or support tickets. If a secret is exposed, replace it at the provider and update the server configuration; removing it from a page is not enough.
Check the public output
Review the built files and browser network responses for secret values. Test the endpoint’s failure behaviour and verify that missing configuration produces a controlled error. OpenAI’s production guidance covers secure key handling; apply the same server-side ownership principle to other providers that issue secret credentials.
