If you’re developing or deploying a payment gateway in Magento 2, you may face different challenges related to various stages of your project. In the following post, we’ve gathered all major tips, tricks, and tutorials related to the Magento 2 payment gateways implementation, so it can essentially simplify your daily work with the platform. Let’s start with some key aspects that you will probably have to master while deploying a payment system within your Magento 2 website.

First of all, there might be a necessity to change configuration files. Hance, you will have to deal with refreshing “Configuration” cache in order to see the changes. Some specialists recommend to disable this cache type, but this approach has one terrible drawback – it significantly slows down the application.

While trying to implement a payment gateway in Magento 2, you have to work with layouts or templates, therefore, don’t forget to disable “Layouts,” “Blocks HTML output,” and “Page Cache.” It is also important to enable them back, when you are done.

When working with classes, keep all the cache types enabled. At the same time, the deployment of Magento 2 payment gateway requires to clean-up var/di and var/generation, if you change the classes public interface or the DI configuration.

And finally, when you are working with JS, CSS, and LESS files, while trying to implement a payment gateway in Magento 2, you may also want to disable or refresh such cache types as “View files fallback” and “View files pre-processing.” It is necessary in case you add or remove such files. For LESS files, cleanup your pub/static folder or turn on developer mode. Please note that both actions lead to a significant decrease of the application’s performance. Additionally, you may use such CLI command as bin/magento dev:css:deploy for processing specific LESS files.
