External platform integration Magento?

Hi. Has anyone tried integration with external platforms, such as marketplaces, through Magento 2? What difficulties arise, and how best to solve them?

Integrating with marketplaces through Magento 2 can be streamlined using tools like magento 2 breadcrumbs on product page , which resolve data synchronization issues and simplify listing management. However, challenges like mismatched attributes can arise. How have you overcome such issues when expanding to external platforms?
