Step-by-Step Guide: Integrating SendexAPI in Minutes

Ready to get started? Follow these simple steps to integrate SendexAPI into your application:

1. Sign Up and Get Your API Key: Create a free account on the SendexAPI website. You'll receive 100 free emails to start. No credit card required to sign up. Once logged in, navigate to the dashboard to find your API key. Keep this key safe and secure; you'll need it to authenticate your requests.
2. Verify Your Domain: To ensure optimal deliverability, you need to verify your domain with SendexAPI. This involves adding two DNS records to your domain's DNS settings. SendexAPI provides a guided flow that walks you through DKIM and SPF setup in under 5 minutes. Access the domain verification section from the dashboard.
3. Send Your First Email: With your API key and verified domain, you're ready to send your first email! SendexAPI uses a simple HTTP POST request to send emails. Here's an example using curl:

curl -X POST https://api.sendex.io/v1/emails \
  -H "Authorization: Bearer sk_live_abc123" \
  -H "Content-Type: application/json" \
  -d '{
    "from": "[email protected]",
    "to": "[email protected]",
    "subject": "Your order is confirmed",
    "html": "<h1>Thanks for your order!</h1>"
  }'

Let's break down this curl command:

• -X POST: Specifies the HTTP method as POST.
• https://api.sendex.io/v1/emails: The SendexAPI endpoint for sending emails.
• -H "Authorization: Bearer sk_live_abc123": Replace sk_live_abc123 with your actual SendexAPI key. This authenticates your request.
• -H "Content-Type: application/json": Sets the content type to application/json, indicating that you're sending a JSON payload.
• -d '{...}': The JSON payload containing the email details:

• from: The sender's email address.
• to: The recipient's email address.
• subject: The email subject.
• html: The email body in HTML format.

After sending the request, you'll receive a JSON response similar to this:

{
  "id": "em_01jqxyz789",
  "status": "queued",
  "sentAt": "2026-03-12T10:00:00Z"
}

This response includes the unique ID of the email (id), the status (status), and the timestamp when the email was sent (sentAt).

Integrating with Different Programming Languages

The beauty of SendexAPI is its simplicity. You can integrate it with any programming language that supports making HTTP requests. Here are a few examples:

• Python: Using the requests library.
• JavaScript: Using fetch or axios.
• PHP: Using curl or file_get_contents.

Simply adapt the curl example above to your preferred language. Remember to replace the API key and email details with your own.

Leveraging Delivery Webhooks

SendexAPI provides real-time delivery webhooks to stay informed about your emails. When events like sent, delivered, bounced, opened, or clicked occur, SendexAPI sends a POST request to a URL you specify. This allows you to track email performance and react accordingly within your application.

For enhanced security, SendexAPI signs the webhook payloads with HMAC. This enables you to verify that the requests are genuinely coming from SendexAPI. Detailed delivery logs are also available in the dashboard for comprehensive tracking. Learn more about how to Track Your Email Performance with SendexAPI's Analytics Dashboard.
