Call ImportService.CreateImportByXml
Batch import multiple subscribers using XML-data. NB! It is recommended that each batch should not be larger than around 2 000 subscribers (there is a file size limitation of 5 Megabyte in place that could cause large batches to fail). The Xml files cannot be encrypeted or password protected. 'XmlData' containing data about imported subscribers in XML format, should be properly encoded depending on request format. See request body examples. The method requires use of demographic name mapping. Please read more by clicking here .
