Using the Brevo API to Create or Update Contacts in Javascript

Introduction to Brevo API Integration

Brevo is a versatile platform offering a range of services including email marketing, SMS campaigns, and contact management. It provides businesses with the tools needed to effectively engage with their audience through personalized communication strategies.

Developers may want to integrate with Brevo's API to streamline contact management processes, such as creating or updating contact information directly from their applications. For example, a developer could use the Brevo API to automatically update customer contact details in response to changes made in a CRM system, ensuring that all communication channels remain synchronized.

Setting Up Your Brevo Test Account for API Integration

Before you can start using the Brevo API to manage contacts, you'll need to set up a Brevo account. This will allow you to generate the necessary API key for authentication and test your integration in a sandbox environment.

Creating a Brevo Account

If you don't already have a Brevo account, follow these steps to create one:

1. Visit the Brevo signup page and register for a free account.
2. Follow the instructions to verify your email address and complete the account setup process.

Generating Your Brevo API Key

Once your account is set up, you need to generate an API key to authenticate your requests:

1. Log in to your Brevo account.
2. Click on your profile name in the top-right corner and select SMTP & API from the dropdown menu.
3. Navigate to the API keys tab and click on Generate a new API key.
4. Enter a name for your API key and click Generate.
5. Copy the generated API key and store it securely, as you'll need it for making API calls.

Making API Calls to Create or Update Contacts with Brevo in JavaScript

To interact with the Brevo API for creating or updating contacts, you will need to use JavaScript. This section will guide you through setting up your environment, writing the necessary code, and handling responses and errors effectively.

Setting Up Your JavaScript Environment for Brevo API Integration

Before making API calls, ensure you have Node.js installed on your machine. You can download it from the official Node.js website. Additionally, you will need the axios library to handle HTTP requests.

npm install axios

Writing JavaScript Code to Create or Update Contacts Using Brevo API

Below is a sample code snippet to create or update a contact using the Brevo API. Replace YOUR_API_KEY with the API key you generated earlier.

const axios = require('axios');

const createOrUpdateContact = async () => {
    const apiKey = 'YOUR_API_KEY';
    const contactData = {
        email: 'example@example.com',
        attributes: {
            FIRSTNAME: 'John',
            LASTNAME: 'Doe',
            SMS: '919876543210'
        },
        listIds: [2],
        updateEnabled: true
    };

    try {
        const response = await axios.post('https://api.brevo.com/v3/contacts', contactData, {
            headers: {
                'api-key': apiKey,
                'Content-Type': 'application/json'
            }
        });
        console.log('Contact created or updated successfully:', response.data);
    } catch (error) {
        console.error('Error creating or updating contact:', error.response ? error.response.data : error.message);
    }
};

createOrUpdateContact();

Understanding the Brevo API Response and Error Handling

After executing the API call, you should verify the response to ensure the contact was created or updated successfully. The response will contain details of the operation, which you can log or process further.

In case of errors, the catch block will capture them. Common errors include invalid API keys or incorrect data formats. Always check the error response for specific details to troubleshoot effectively.

Verifying Contact Creation or Update in Brevo

To confirm that the contact was successfully created or updated, log in to your Brevo account and navigate to the contacts section. You should see the new or updated contact details reflected there.

For more detailed information on error codes and handling, refer to the Brevo API documentation.
