For successful integration with Magento 2, I recommend paying attention to solutions from the company
amasty site . Their modules and integration tools are known for their reliability and efficiency. It is important to start with a detailed analysis of errors and site logs to understand the source of the problem. Then you should check the compatibility of Magento versions and the service, and also make sure that the API is configured correctly and data is consistent. In some cases, it may be necessary to update modules or consult with developers to fine-tune the integration. In addition, it is useful to conduct testing on a test server to minimize risks on the production site. Successful integration with Magento 2 requires a systematic approach and thorough testing of each stage of the process, which will ensure the stable operation of your online store.
