One of the trickiest parts of automation is handling secrets: API keys, tokens, and passwords that let your workflows act on other systems. Tines 3B's answer is the credential proxy, a component that sits between your running code and the outside world and adds the right authentication to each request as it leaves.
The credential proxy is an automated service that acts as a secure intermediary between your workflows and external applications. Instead of managing sensitive credentials manually for every task, the proxy automatically injects the necessary authentication details (such as API keys, OAuth tokens, or basic auth) only when they are needed.
Key benefits
Seamless authentication: Once your applications are connected, the proxy handles the authentication process automatically. You don't need to manage credentials at the individual workflow step level.
Reduced complexity: The proxy dynamically matches outgoing requests to the correct app, ensuring that the right credentials are applied to the right service without manual intervention.
Simplified management: Authentication handles are centralized, making it easier to manage connections across your entire workspace.
Robust security features
The credential proxy is designed with a "security-first" architecture to protect your sensitive data:
Encrypted handling: Credentials are encrypted while in transit and are only decrypted in memory during the execution of your workflow. They are cleared immediately after the task is complete.
Protection against unauthorized requests: We employ strict security checks to ensure that your workflows do not send data to unauthorized, private, or local destinations.
Request scoping: Authentication is strictly scoped to the specific application you have connected. Requests are only authorized if they match verified URL patterns, preventing credential leakage to unintended destinations.
Hermetic execution modes: For sensitive environments, we offer restricted modes that can block all external traffic, providing an additional layer of control during testing or sensitive operations.
Supported authentication methods
The credential proxy is built to support a wide range of industry-standard authentication methods, including:
API keys (via headers or query parameters)
OAuth 2.0
Bearer tokens
Basic authentication (Username/Password)
AWS signature v4
JWT (JSON Web Tokens)
