Step by Step Guide to Building a Kartra API Integration in Python

Introduction

Hey there, fellow developer! Ready to dive into the world of Kartra API integration? You're in for a treat. Kartra's API is a powerful tool that can supercharge your marketing automation efforts. In this guide, we'll walk through building a robust integration in Python. Let's get cracking!

Prerequisites

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

A Python environment set up (3.6+ recommended)
The requests library installed (pip install requests)
Your Kartra API credentials handy

Trust me, having these ready will save you headaches down the road.

Authentication

First things first, let's get you authenticated:

Grab your API key and password from your Kartra account.
Set up your authentication headers like this:

headers = {
    'Content-Type': 'application/json',
    'API-KEY': 'your_api_key',
    'API-PASSWORD': 'your_api_password'
}

Easy peasy, right? Now you're ready to make some requests!

Basic API Request Structure

Kartra's API follows a pretty standard RESTful structure. Here's the gist:

Base URL: https://app.kartra.com/api
HTTP methods: GET, POST, PUT, DELETE (you know the drill)
Payload format: JSON (our old friend)

Here's a quick example to get you started:

import requests
import json

url = 'https://app.kartra.com/api/lead/list'
response = requests.get(url, headers=headers)

Implementing Core Functionalities

Retrieving Data

Want to fetch some leads? Here's how:

def get_leads():
    url = 'https://app.kartra.com/api/lead/list'
    response = requests.get(url, headers=headers)
    return response.json()

Creating and Updating Resources

Adding a new lead is just as simple:

def add_lead(lead_data):
    url = 'https://app.kartra.com/api/lead/create'
    response = requests.post(url, headers=headers, json=lead_data)
    return response.json()

Handling API Responses

Always check your responses! Kartra will send you JSON, so parse it like this:

response_data = response.json()
if response.status_code == 200:
    # Do something with response_data
else:
    print(f"Error: {response_data.get('message')}")

Kartra uses cursor-based pagination. Here's a quick implementation:

def get_all_leads():
    url = 'https://app.kartra.com/api/lead/list'
    all_leads = []
    while url:
        response = requests.get(url, headers=headers)
        data = response.json()
        all_leads.extend(data['leads'])
        url = data.get('next_page_url')
    return all_leads

And don't forget to respect those rate limits! Kartra's pretty generous, but it's always good practice.

Best Practices

Log your errors. Future you will thank present you.
Cache responses when it makes sense. Your API quota (and response times) will thank you.
Consider using async requests for heavy lifting. aiohttp is your friend here.

Testing the Integration

Always test your code! Here's a simple unit test to get you started:

import unittest

class TestKartraIntegration(unittest.TestCase):
    def test_get_leads(self):
        leads = get_leads()
        self.assertIsInstance(leads, list)
        self.assertTrue(len(leads) > 0)

if __name__ == '__main__':
    unittest.main()

Conclusion

And there you have it! You're now armed with the knowledge to build a solid Kartra API integration in Python. Remember, this is just the beginning. There's so much more you can do with Kartra's API – from managing campaigns to tracking user behavior.
