How to Sync Salesforce Leads in Under 10 Lines of Code

Integrating with powerful platforms like Salesforce is a common requirement for modern applications. But let's be honest: it can be a major headache. You're often faced with wrestling complex SDKs, navigating confusing documentation, and building fragile, boilerplate-heavy authentication flows just to perform a single action. What if you could skip all that and just... call a function?

Forget the authentication dance and the overhead of maintaining custom connectors. With Integrations.do, we're changing the game by treating integrations as simple, reusable services. This "Business-as-Code" approach turns complex API interactions into straightforward function calls you can embed directly in your application.

In this post, we'll show you how to create a new lead in Salesforce with a surprisingly small amount of code.

The Old Way: A Mountain of Complexity

Before we jump into the solution, let's quickly recap the typical challenges of a Salesforce integration:

• Authentication Hell: Salesforce uses OAuth 2.0, which means you need to manage a multi-step authorization flow, securely store client secrets, and handle access and refresh tokens.
• SDK Overload: You need to learn a specific, often heavy, client library for your language of choice.
• API Versioning: You have to keep track of API versions and manage breaking changes.
• Error Handling: Building resilient error handling and retry logic for a remote service adds another layer of complexity.

All this work is just table stakes—it's plumbing you have to build before you can write a single line of valuable business logic.

The New Way: Integrations as Code

Integrations.do operates on a simple but powerful philosophy: Integrations as Code. Our AI-powered platform abstracts away the complexity. You connect your Salesforce account once in our secure environment, and we handle the rest.

Our agentic workflow platform securely manages credentials, handles token refreshes, and provisions the entire Salesforce API as a simple service you can call via our universal SDK.

Syncing a Salesforce Lead: The Code

Ready to see how simple it is? Here’s all the code you need to create a new lead in Salesforce using the .do client.

import { Client } from '@do-sdk/client';

// Initialize the .do client
const doClient = new Client({ apiKey: 'YOUR_API_KEY' });

// Access any integration as a simple function call
async function syncNewLead(leadData) {
  try {
    const newLead = await doClient.integrations.salesforce.createLead({
      body: leadData
    });
    console.log('Lead synced successfully:', newLead.id);
    return newLead;
  } catch (error) {
    console.error('Failed to sync lead:', error);
  }
}

// Run the workflow
syncNewLead({
  firstName: 'Jane',
  lastName: 'Doe',
  email: 'jane.doe@example.com',
  company: 'ACME Corp'
});

Let's Break It Down

That's it. Under 10 lines of functional code. Let's look at what's happening:

1. Initialize the Client: We import and initialize the @do-sdk/client with our API key. This single client is your gateway to all your integrations.
2. Call the Service: The magic happens at doClient.integrations.salesforce.createLead. This looks and feels like a native function call because that's what it is. There's no REST client setup, no auth headers, no token management. You simply call the integration (salesforce) and the action (createLead).
3. Pass the Data: The body object contains the lead data, which maps directly to the fields in Salesforce.
4. Get the Result: The function returns a promise that resolves with the response from the Salesforce API, including the ID of the newly created lead.

Behind this simple call, the Integrations.do platform is authenticating the request, making the secure API call to Salesforce, and returning the response.

Beyond a Single API Call

The real power of this model emerges when you realize this same pattern applies to everything. Need to add that same lead to a Mailchimp list? It's just another function call:

// Example: Add lead to Mailchimp after Salesforce sync
await doClient.integrations.mailchimp.addListMember({
    listId: 'YOUR_LIST_ID',
    body: {
        email_address: leadData.email,
        status: 'subscribed',
        merge_fields: {
            FNAME: leadData.firstName,
            LNAME: leadData.lastName
        }
    }
});

By turning every API into a consistent, callable service, you can build powerful, automated workflows without the integration overhead. This is the essence of Workflow Automation in a developer-native environment.

Why This Beats Traditional iPaaS

Unlike traditional UI-based iPaaS (Integration Platform as a Service) tools that lock your logic into a drag-and-drop interface, our "Business-as-Code" approach offers significant advantages:

• Version Control: Your integration logic lives in your Git repository, just like the rest of your code.
• Developer-Friendly: Stay in your IDE. No context-switching to a separate platform to build or debug logic.
• Testability: Write unit and integration tests for your workflows using standard testing frameworks.
• CI/CD Native: Your integrations become part of your existing CI/CD pipelines, enabling true DevOps for your business processes.
