In today's fast-paced digital landscape, automation is no longer a luxury—it's a necessity. But as we build increasingly complex systems, a single point of failure can bring a critical process to a grinding halt, leaving data in inconsistent states and causing headaches for developers and customers alike. How do we build automations that are not just powerful, but also fundamentally reliable?
The answer lies in thinking small. At the .do platform, we believe the foundation of robust automation is the atomic action: the smallest, indivisible unit of work. With action.do, we provide the tools to define, execute, and manage these fundamental building blocks, empowering you to embrace Business-as-Code and build agentic workflows with unparalleled precision.
An atomic action is a single, specific task that is guaranteed to either complete successfully or fail entirely, with no in-between state. Think of it as a single, unbreakable step in a complex recipe.
This "all-or-nothing" principle is a cornerstone of reliable systems. In business operations, it means you can execute a task like "update a database record," "charge a credit card," or "send an API call" with confidence, knowing it won't leave your system in a confusing, partially completed state. This prevents data corruption, ensures process integrity, and makes your workflows resilient by design.
While individual actions are simple, their true power is realized when they are composed into larger service.do workflows. By breaking down a complex business process into a series of discrete, reusable atomic actions, you gain immense flexibility and control.
Instead of writing a single, monolithic script that's difficult to debug and maintain, you can build a modular workflow from a library of pre-defined actions.
Each action is an independent, API-callable unit that can be versioned, tested, and reused across countless workflows. This modularity is the key to building scalable, maintainable, and truly agentic systems.
Let's look at how simple and reliable this becomes in practice. Imagine you need to send a welcome email to a new user. Using the .do SDK, executing this predefined action is straightforward.
import { Do } from '@do-platform/sdk';
// Initialize the .do client with your API key
const client = new Do({ apiKey: 'YOUR_API_KEY' });
// Execute a predefined atomic action by name
async function sendWelcomeEmail(userId: string) {
try {
const result = await client.action.execute({
name: 'send-welcome-email',
params: {
recipientId: userId,
template: 'new-user-welcome-v1'
}
});
console.log('Action Executed Successfully:', result.id);
return result;
} catch (error) {
console.error('Action Failed:', error);
}
}
// Run the action for a new user
sendWelcomeEmail('user_12345abc');
In this example, the send-welcome-email action encapsulates all the logic—finding the user's email, rendering the correct template, and interacting with an email service provider. Your main application doesn't need to know the details; it just needs to invoke the action. If the email service is down or the template is missing, the action fails cleanly, and your system can log the error and retry later without affecting other parts of the user onboarding process.
Adopting atomic actions for your workflow automation delivers tangible business advantages:
Atomic actions are more than just a technical concept; they are a strategic advantage. By building your operations on a foundation of small, reliable, and reusable units, you pave the way for powerful workflow automation that is robust, scalable, and easy to maintain.

Q: What is an 'atomic action' in the context of .do?
A: An atomic action is the smallest, indivisible unit of work within a workflow. It represents a single, specific task—like sending an email or updating a database record—that either completes successfully or fails entirely, ensuring system reliability and preventing partial states.
Q: How do actions differ from services?
A: An action (action.do) is a single, granular operation. A service (service.do) is a higher-level business capability composed of one or more actions orchestrated into a workflow. Actions are the building blocks; services are the valuable outcomes.
Q: Can I create my own custom actions?
A: Yes. The .do platform empowers you to define your own custom actions using Business-as-Code. You can encapsulate any business logic, external API call, or script into a reusable, versioned, and callable action for your agentic workflows.
Q: How are actions invoked?
A: Actions are invoked programmatically through the .do API or our language-specific SDKs. You simply call the action by its unique name and provide the necessary parameters, allowing for seamless integration into any application or system.
Q: What happens when an action fails?
A: Because actions are atomic, a failure is handled cleanly without leaving your system in an inconsistent state. The platform provides detailed error logging and allows you to configure automated retries, notifications, or alternative compensatory actions.
