Xero API InvalidContactEmail error when sending an invoice via Xero API.

The email address for the contact is not valid.

Understanding Xero API

Xero API is a powerful tool designed to help businesses manage their accounting and financial operations seamlessly. It allows developers to integrate Xero's accounting software with other applications, enabling automated invoicing, payment processing, and financial reporting. The API is widely used in the FinTech industry for its robust features and ease of integration.

Identifying the Symptom

When using the Xero API, you might encounter the InvalidContactEmail error. This error typically occurs when attempting to send an invoice to a contact whose email address is not formatted correctly. The API will return this error, preventing the invoice from being sent.

Common Error Message

The error message you might see is: InvalidContactEmail: The email address for the contact is not valid.

Exploring the Issue

The InvalidContactEmail error indicates that the email address associated with a contact in your Xero account does not adhere to standard email formatting rules. This could be due to missing '@' symbols, incorrect domain names, or other formatting issues.

Why This Happens

This error is often caused by user input errors or data migration issues where email addresses are not validated before being entered into the system.

Steps to Fix the Issue

To resolve the InvalidContactEmail error, follow these steps:

Step 1: Validate Email Format

Ensure that the email address is correctly formatted. A valid email address should follow the pattern: [email protected]. Use regular expressions to validate email formats programmatically. For example, in JavaScript, you can use:

const emailRegex = /^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$/;
const isValidEmail = emailRegex.test(contactEmail);

Step 2: Update Contact Information

Log into your Xero account and navigate to the contact list. Locate the contact with the invalid email and update it with a valid email address. Ensure there are no typos or formatting errors.

Step 3: Test the API Call

After updating the email address, attempt to resend the invoice using the Xero API. If the email is valid, the API should process the request without returning the error.
