Seamlessly Connect Your World: Automating Stripe, GitHub, and Slack

In today's fast-paced digital environment, efficiency is king. Your business relies on a suite of powerful tools like Stripe for payments, GitHub for code, and Slack for communication. But when these tools don't talk to each other, you're left with manual, repetitive tasks that drain time and invite human error. What if you could connect them all, creating a seamless, automated workflow that just works?

Enter trigger.do, the platform for event-driven automation. With trigger.do, you can initiate complex workflows and agentic actions based on real-time events. This post will walk you through creating a powerful automation: when a customer pays via Stripe, a private GitHub repository is automatically created for them, and a notification is sent to your team's Slack channel.

Let's trigger anything and automate everything.

The Problem: The Manual Workflow Silo

Imagine this common scenario:

1. A new client signs up and pays for your service using Stripe. A "Payment Successful" email lands in your inbox.
2. A project manager sees the email, finds the customer's details, and manually creates a new private repository on GitHub to store their project files.
3. The manager then navigates to Slack, finds the right channel, and posts a message to let the development team know the new project is ready.

Each step is a potential point of failure. Details can be mistyped, notifications can be forgotten, and as your business grows, this process becomes an unsustainable bottleneck.

The Solution: Event-Driven Automation with trigger.do

The key to solving this is to think in terms of events and actions. The "event" or workflow trigger is the specific occurrence that starts the process. In our case, the trigger is a successful payment in Stripe. The "actions" are the tasks we want to automate in response: creating a GitHub repo and sending a Slack message.

trigger.do acts as the central nervous system for your applications. It listens for triggers from any source—webhooks, scheduled tasks, API calls, or custom events—and executes your predefined workflows with unparalleled reliability.

Building the Stripe-to-GitHub-to-Slack Workflow

Let's build this automation. With the trigger.do SDK, you can define this entire multi-step process in a single, easy-to-read file.

Step 1: The Trigger - Capturing a Stripe Webhook

First, we define our trigger. We'll listen for the customer.subscription.created event from Stripe. trigger.do provides a secure, reliable endpoint to receive this webhook, so you don't have to manage the infrastructure.

import { trigger } from "@do/sdk";
import { stripe } from "./integrations/stripe";
import { github } from "./integrations/github";
import { slack } from "./integrations/slack";

// Our main workflow trigger
const newCustomerOnboarding = trigger.on(stripe.events.customerSubscriptionCreated, {
  name: "New Customer: Stripe to GitHub to Slack",
  // ... the workflow logic goes here
});

Step 2: The Action - Create a Private GitHub Repo

Once the trigger fires, the run function is executed. It receives the Stripe event payload, which contains all the customer information we need. We'll use the customer's ID to create a unique repository name and then call the GitHub API to create it.

// ... inside the trigger definition
run: async (event, context) => {
  const customerId = event.data.object.customer;
  const repoName = `project-${customerId}`;

  context.logger.info("New customer detected. Creating GitHub repo.", { customerId });

  // Action 1: Create a private repository on GitHub
  const repo = await github.repos.createForAuthenticatedUser({
    name: repoName,
    private: true,
  });

  // ... next action
}

Step 3: The Notification - Announce in Slack

With the repository created, the final step is to notify the team. We use the data from the previous steps—the customer ID and the new repository URL—to compose a helpful message and post it to a designated Slack channel.

// ... inside the run function, after creating the repo
  context.logger.info("Repo created. Sending Slack notification.");

  // Action 2: Post a message to the #new-customers channel
  await slack.chat.postMessage({
    channel: "#new-customers",
    text: `🎉 New Customer Onboarded!
- *Customer ID:* ${customerId}
- *GitHub Repo:* <${repo.data.html_url}|${repoName}>`,
  });

  return { success: true, repoUrl: repo.data.html_url };
}

The Complete Code

Here is the complete, production-ready workflow. It's concise, declarative, and powerfully connects three distinct services into one seamless process.

import { trigger } from "@do/sdk";
import { stripe } from "./integrations/stripe"; // Your configured integrations
import { github } from "./integrations/github";
import { slack } from "./integrations/slack";

// Trigger a workflow when a new subscription is created in Stripe
const newCustomerOnboarding = trigger.on(stripe.events.customerSubscriptionCreated, {
  name: "New Customer: Stripe to GitHub to Slack",
  run: async (event, context) => {
    const customerId = event.data.object.customer;
    const repoName = `project-${customerId}`;

    context.logger.info("New customer detected. Creating GitHub repo.", { customerId });

    // Action 1: Create a private repository on GitHub
    const repo = await github.repos.createForAuthenticatedUser({
      name: repoName,
      private: true,
    });
    
    context.logger.info("Repo created. Sending Slack notification.");

    // Action 2: Post a message to the #new-customers channel
    await slack.chat.postMessage({
      channel: "#new-customers",
      text: `🎉 New Customer Onboarded!
- *Customer ID:* ${customerId}
- *GitHub Repo:* <${repo.data.html_url}|${repoName}>`,
    });

    return { success: true, repoUrl: repo.data.html_url };
  },
});

Why trigger.do is Built for This

Creating robust automations involves more than just calling APIs. trigger.do is engineered for reliability and scale.

• Automatic Retries: What if the GitHub API is temporarily down? trigger.do automatically retries the action with exponential backoff, ensuring your workflow completes even during transient failures.
• Detailed Logging: Every trigger, run, and action is logged, giving you complete visibility for easy debugging.
• Complex Chains: The power doesn't stop here. The successful completion of one workflow can be a custom event that triggers another, allowing you to build incredibly complex, multi-step agentic automations.
• More Than Webhooks: While this example uses a webhook, you can also trigger workflows on a recurring schedule (cron jobs), a direct API call, or from custom events within your own application.

Start Connecting Your World

You've just seen how to eliminate a tedious manual process and replace it with a fast, reliable, and scalable automated workflow. This is just one example. Imagine automating user de-provisioning, syncing data between a CRM and a support desk, or running nightly data processing jobs.

If you can script it, you can trigger it.
