For the majority of our Stripe Payments Plugin users, the generic text and messages displayed by the plugins should be sufficient. Some of the site administrators may want to customize certain payment pop-up-related messages. They are able to achieve this using the free Custom Messages Addon.
For a small percentage of Stripe Payment Plugin users, their specific website may require that certain messages are altered entirely. For this kind of specific customization of text/messages displayed by the Stripe Payments Plugin, you may need to alter the language file.
Generally, the language file is used to translate a plugin from one language to another, but surprisingly this can also be used to achieve customization of certain phrases output by the plugin. To customize generic text or messages that are displayed by the Stripe Payments Plugin you can follow the translation documentation found here. Instead of translating from one language to another, you will simply specify the text you wish for the plugin to show.
If you wish to alter certain text or messages displayed by the Stripe Payments Plugin, you may need to edit the language file in a similar way you would if you were attempting to translate the plugin.
