Here are some tips, solutions to common problems, and guides for testing.

Tips

Create a Sandbox Account

Before doing any development for the Authorize.Net suite of APIs, be sure to create a Sandbox Account with Authorize.Net. With it you can simulate virtually every aspect of the Authorize.Net production APIs without incurring any fees.

Use a webhook testing site to test webhooks

Having a full understanding of what a webhook looks like makes working with webhooks easier. You can inspect an Authorize.Net webhook using a third party service like webhook.site.

FAQ

Solutions to common problems when integrating the AuthnetJSON library into your project.

php://input is empty, POST is empty, webhook has no data

This may happen because a redirect occurred and steps were not taken to persist that data across the redirect. Look for redirects to HTTPS or to/from the www subdomain in your .htaccess or web.config file.

Class 'authnet\className' not found

• This may happen if you did not include the Composer autoload.php file in your project

  require __DIR__.'/vendor/autoload.php';
