In the world of workflow automation, complexity is the enemy of reliability. As business processes become more interconnected, a single failure in a multi-step script can cascade, leaving your systems in a messy, inconsistent state. How do you build complex, agentic workflows that are both powerful and resilient? The answer lies in mastering the fundamental unit of work: the atomic action.
On the .do platform, action.do is your tool for defining and executing these atomic operations. It allows you to encapsulate single, indivisible tasks into reliable, API-callable units. This is the foundation of turning your business logic into robust, scalable Business-as-Code.
Think of an atomic action as the smallest possible unit of work that must be completed in its entirety. It either succeeds completely or fails completely, with no in-between states.
An excellent analogy is a bank transfer. The entire process—debiting one account and crediting another—is a single, atomic transaction. You would never want the system to complete only the debit part and then fail, leaving the money in limbo. The transfer must happen all at once, or not at all.
This is the principle behind action.do. Each action is a guaranteed, indivisible operation, such as:
By ensuring each step is atomic, you eliminate the risk of partial failures and create workflows that are predictable, reliable, and easy to debug.
The true power of action.do emerges when you adopt a Business-as-Code mindset. Instead of writing long, monolithic scripts, you break down complex processes into a library of discrete, reusable actions.
This approach offers significant advantages:
Invoking an action is designed to be seamless. Using the .do SDK, you can execute any predefined action by its unique name and pass in the required parameters. The platform handles the underlying execution, logging, and error management.
Here’s how you would execute a send-welcome-email action using our TypeScript SDK:
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');
The try...catch block is crucial. Because actions are atomic, a failure is caught cleanly as a single exception, allowing you to implement precise error handling, retries, or compensatory logic without untangling a partially completed workflow.
It’s important to understand the hierarchy within the .do platform. If actions are the bricks, services are the complete structures you build with them.
For example, a New User Onboarding service might orchestrate several atomic actions in sequence:
By building with action.do, you create a robust foundation that makes defining and managing high-level services like service.do incredibly efficient and reliable.
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.
Stop wrestling with brittle scripts and start architecting for resilience. By embracing atomic action.do, you gain the power to build complex, agentic workflows with the confidence that they are modular, maintainable, and fundamentally reliable.
