Step by Step Guide to Building a Process Street API Integration in JS

Introduction

Hey there, fellow code wranglers! Ready to dive into the world of Process Street API integration? Buckle up, because we're about to embark on a journey that'll supercharge your workflow automation game. This guide will walk you through creating a slick JavaScript integration that'll have you manipulating workflows and tasks like a pro.

Prerequisites

Before we jump in, make sure you've got:

• A Process Street API key (snag one from your account settings)
• Node.js and npm installed (you know the drill)

Setting Up Your Dev Environment

First things first, let's get our project off the ground:

mkdir process-street-integration
cd process-street-integration
npm init -y
npm install axios dotenv

Create a .env file for your API key:

PROCESS_STREET_API_KEY=your_api_key_here

Authentication

Let's set up our API client with authentication:

require('dotenv').config();
const axios = require('axios');

const client = axios.create({
  baseURL: 'https://api.process.st/api/v1',
  headers: {
    Authorization: `Bearer ${process.env.PROCESS_STREET_API_KEY}`,
    'Content-Type': 'application/json'
  }
});

Basic API Requests

Now, let's fetch some workflows:

async function getWorkflows() {
  try {
    const response = await client.get('/workflows');
    console.log(response.data);
  } catch (error) {
    console.error('Error fetching workflows:', error.response.data);
  }
}

getWorkflows();

Creating a task? Easy peasy:

async function createTask(workflowRunId, taskId) {
  try {
    const response = await client.post(`/workflow-runs/${workflowRunId}/tasks/${taskId}/complete`);
    console.log('Task completed:', response.data);
  } catch (error) {
    console.error('Error creating task:', error.response.data);
  }
}

Handling Responses

Process Street's API speaks JSON. Here's how to listen:

async function handleApiResponse(apiCall) {
  try {
    const response = await apiCall();
    return response.data;
  } catch (error) {
    if (error.response) {
      console.error('API Error:', error.response.status, error.response.data);
    } else {
      console.error('Network Error:', error.message);
    }
    throw error;
  }
}

Advanced Features

Want to paginate through results? We've got you covered:

async function getAllWorkflows() {
  let page = 1;
  let allWorkflows = [];
  
  while (true) {
    const response = await client.get('/workflows', { params: { page, limit: 100 } });
    allWorkflows = allWorkflows.concat(response.data);
    
    if (response.data.length < 100) break;
    page++;
  }
  
  return allWorkflows;
}

Webhooks

Stay in the loop with real-time updates:

const express = require('express');
const app = express();

app.post('/webhook', express.json(), (req, res) => {
  console.log('Webhook received:', req.body);
  res.sendStatus(200);
});

app.listen(3000, () => console.log('Webhook server running on port 3000'));

Best Practices

• Respect rate limits: Implement exponential backoff for retries.
• Cache frequently accessed data to reduce API calls.
• Use environment variables for sensitive info (like we did with the API key).

Testing

Don't forget to test! Here's a quick Jest example:

jest.mock('axios');

test('getWorkflows fetches workflows successfully', async () => {
  axios.get.mockResolvedValue({ data: [{ id: 1, name: 'Test Workflow' }] });
  const workflows = await getWorkflows();
  expect(workflows).toHaveLength(1);
  expect(workflows[0].name).toBe('Test Workflow');
});

Deployment

When you're ready to ship:

1. Ensure all sensitive data is in environment variables.
2. Set up proper error logging and monitoring.
3. Consider using a process manager like PM2 for Node.js apps.

Conclusion

And there you have it! You're now armed with the knowledge to build a robust Process Street API integration. Remember, the API is your oyster – get creative and build something awesome!
