When you send an article for translation, you are sending the article text along with other HTML information, including the URLs for hyperlinked text. But if your article is linking to articles in the same language, won't that mean that once translated into different languages, all the hyperlinks point to that original language version?
By default, we won't change the URL of the hyperlink, merely the anchor text. However, we can toggle a feature that is able to localize these URLs during the translation. This ensures that if you are translating an English article into Spanish, for example, any URL looking like https://help.unbabel.com/hc/en-us/articles/17030253798679 will be adjusted to https://help.unbabel.com/hc/es/articles/17030253798679, ensuring a Spanish reader will open the Spanish version of the linked article
Note: if enabled, the feature localizes all URLs, even if you don't have a version for that language published/drafted.
Note2: the feature only works for articles of the same Zendesk Help Center.
