Hi Toms, If you have elements in your XML file whose type is a complex type, xsi:type specifies the particular complex type. Are you trying to add a Label <https://developers.google.com/adwords/api/docs/reference/v201702/LabelService.Label> or a Content Label <https://developers.google.com/adwords/api/docs/reference/v201702/CampaignCriterionService.ContentLabel>? If you are trying to add a content label, you will need to use AdGroupCriterionService <https://developers.google.com/adwords/api/docs/reference/v201702/AdGroupCriterionService> or the CampaignCriterionService <https://developers.google.com/adwords/api/docs/reference/v201702/AdGroupCriterionService>. If you are trying to add a Label, the xsi_type should be 'TextLabel'. The xsi_type can be found out from the Production WSDL listed under corresponding service.
Let me know if you have any further questions.
