Overview

Sending emails from Xano with a custom script? It's actually pretty straightforward. First, you'll need to set up your email server credentials. Easy enough, right? Then, configure the script to use these details. Next, it's all about integrating that script within Xano's API. You'll probably utilize Xano's scripting features and libraries, including SMTP for email protocols. Don't forget—handling exceptions and testing the email feature are super critical to make sure everything runs smoothly. This guide will take you through every step, providing useful tips and best practices along the way.

How to send emails from Xano using a custom script?

Step 1: Setting Up Xano Environment

  1. Log in to your Xano account.
  2. Head over to the workspace where you want to add the email feature.
  3. Create a new API endpoint or pick an existing one where you want to add the email-sending functionality.

Step 2: Create a Custom Function

  1. Under the endpoint, click on 'Add Function'.
  2. Choose "Custom Function".
  3. Give your function a name (e.g., sendEmail).

Step 3: Define Input Parameters

  1. Go to the "Inputs" tab of your custom function.
  2. Define the input parameters you need, like:
    • to: The recipient's email address.
    • subject: The subject of the email.
    • body: The HTML or text body of the email.
    • from (optional): The sender's email address.

Step 4: Write the Custom Script

  1. Go to the "Script" tab of your custom function.
  2. Write the script to send an email. You can use a third-party email service like SendGrid, Mailgun, or any SMTP server.

Example using SendGrid:

const sgMail = require('@sendgrid/mail'); sgMail.setApiKey('YOUR_SENDGRID_API_KEY'); const msg = { to: XANO["to"], from: XANO["from"] || 'default@yourdomain.com', // Set a default from address subject: XANO["subject"], text: XANO["body"], html: XANO["body"], }; sgMail .send(msg) .then(() => { console.log('Email sent'); }) .catch((error) => { console.error(error); });

Replace 'YOUR_SENDGRID_API_KEY' with your actual SendGrid API key.

Step 5: Add the Custom Function to the Endpoint Workflow

  1. Go back to the workflow of your API endpoint.
  2. Click on "Add Function" and choose your custom function sendEmail.
  3. Map the input parameters with the appropriate fields from the endpoint.

Step 6: Testing

  1. Save your API endpoint and custom function.
  2. Use a tool like Postman or Xano's built-in API testing tool to send a request to your endpoint.
  3. Check that the email is successfully sent to the recipient.

Step 7: Error Handling and Logging

  1. Add error handling in your custom script to catch and log any issues with sending the email.
  2. You can log errors to a database or monitoring service for later review.

Example:

sgMail .send(msg) .then(() => { console.log('Email sent'); }) .catch((error) => { console.error('Email not sent:', error); // Optionally log to a database or monitoring service. });

Remember to replace placeholders with actual values and keep your third-party service credentials secure.
