I’m trying to create a private application to communicate with the United States immigration case tracker, but I need to insert the authentication keys from the immigration application into the private hubspot application and I can’t do this configuration, could anyone help me?

Hi @JReis5,

You can securely store keys for HubSpot private app use by utilizing [secrets](https://developers.hubspot.com/docs/guides/cms/tools/local-development-cli#add-a-secret), which can then be used by the private app with [serverless functions](https://developers.hubspot.com/docs/guides/cms/content/data-driven-content/serverless-functions/).

Depending on your use case, this can also be used with [custom code actions](https://developers.hubspot.com/docs/reference/api/automation/custom-code-actions) in workflows and secrets would be created in the UI.
