Secure-by-Design: Managing Credentials and Secrets in Your Automations

As developers, we love the power of automation. Building a software robot or an AI agent that takes a complex, manual business process and transforms it into a swift, reliable workflow is incredibly satisfying. Whether it's processing invoices from an email inbox or integrating data between legacy and modern systems, Robotic Process Automation (RPA) brings the power of code to the challenges of operations.

But with great power comes great responsibility.

These powerful automations often need to interact with secure systems, databases, and third-party APIs. This requires credentials: API keys, usernames, passwords, and access tokens. And how you manage these secrets can be the difference between a secure, enterprise-grade solution and a critical security vulnerability waiting to happen.

Hardcoding credentials directly into your scripts or configuration files is not an option. It's the digital equivalent of leaving your house keys under the doormat. In this post, we'll explore the principles of secure-by-design automation and how a developer-first platform like rpa.do solves the critical challenge of secret management from the ground up.

The Alarming Risks of Poor Secret Management

When building an automation, it's tempting to take shortcuts to get a proof-of-concept running. You might paste an API key directly into your code or place it in a plain-text config file. While this might work on your local machine, it creates massive risks when deployed:

Source Control Exposure: If your code is committed to a Git repository—even a private one—the secret is now part of the history. If the repository ever becomes public, your secret is exposed to the world.
Difficult Rotation: When a key is compromised or needs to be rotated as part of security best practices, you have to hunt it down in your code, change it, test it, and redeploy. This is slow, error-prone, and inefficient.
Lack of Access Control: A hardcoded key gives anyone who can read the code access to that secret. There’s no way to enforce the "Principle of Least Privilege," where an agent or user only has access to the specific secrets they absolutely need.
No Audit Trail: You have no way of knowing who or what accessed a secret, and when. This makes security audits and incident response nearly impossible.

A Better Way: Secure Vaults and the "Business-as-Code" Philosophy

The same "as-code" philosophy that makes modern software development so powerful also provides the solution to secret management. Just as we define infrastructure with code, we should manage automation workflows and their dependencies—including secrets—programmatically and securely.

This is where a centralized, secure secret vault comes in. Instead of scattering credentials throughout your codebase, a secure-by-design RPA platform provides a dedicated, encrypted vault.

Benefits of a built-in secret vault:

Centralization: A single, secure source of truth for all credentials.
Encryption: Secrets are encrypted both at rest and in transit.
Granular Access Control: Define exactly which agents can access which secrets.
Simplified Rotation: Update a secret in one place, and all automations using it are instantly updated without a code change or redeployment.
Complete Auditability: Every access request is logged, providing a clear audit trail.

How rpa.do Bakes Security into Your Workflows

At rpa.do, we believe that security shouldn't be an afterthought. Our developer-first platform is built on the idea that robust, scalable automations must be secure by design. That’s why our Intelligent Automation API includes a secure, built-in vault for managing all your credentials.

Instead of putting sensitive data in your code, you simply reference it. Here’s how it works:

Store Your Secret: You add your credential (e.g., a QuickBooks API key) to the rpa.do vault via our secure interface or management API. You give it a memorable name, like quickbooks-prod-key.
Reference the Secret in Your Code: In your RPA agent's code, you never write the actual key. You simply reference its name from the vault.
Secure Injection at Runtime: When your agent runs, the rpa.do platform securely fetches the encrypted secret from the vault and injects it into the agent's execution environment just-in-time. The secret is never exposed in your source code, version history, or logs.

Let's look at our invoice processing agent example. Notice how the apiKey is referenced, not hardcoded.

import { Agent } from '@do/rpa';

// Create an RPA agent to handle invoice processing
const invoiceAgent = new Agent('invoice-processor-agent');

// Define and run the automation workflow
async function runInvoiceProcessing() {
  const result = await invoiceAgent.run({
    workflow: 'process_new_invoices',
    source: {
      type: 'email_inbox',
      id: 'invoices@company.com'
    },
    destination: {
      type: 'quickbooks_api',
      action: 'create_bill',
      // The platform securely injects the key referenced from the vault
      auth: {
        apiKey: '@vault:quickbooks-prod-key' 
      }
    }
  });

  console.log(`Automation complete. ${result.processed} invoices processed.`);
}

runInvoiceProcessing();

This declarative, "Business-as-Code" approach makes your automation cleaner, easier to maintain, and fundamentally more secure. You can rotate the quickbooks-prod-key in the rpa.do vault at any time, and the invoiceAgent will use the new key on its next run—no code changes required.

Build Automations You Can Trust

In today's fast-paced digital landscape, workflow automation is essential for staying competitive. But speed cannot come at the expense of security. By moving beyond brittle UI bots and adopting an API-first, code-based approach to RPA, you gain the ability to build sophisticated AI agents that are not only powerful but also resilient and secure.

Managing credentials and secrets is a foundational piece of that puzzle. A platform that treats security as a core feature empowers you to automate anything, from simple data entry to complex, multi-system integrations, with complete confidence.
