Communication with TARGET Services in application-to-application mode is carried out via ISO 20022-compliant messages. While the basic features of the messages are described in the respective User Detailed Functional Specifications (UDFS), the specific usage guidelines can be found in the online portal “MyStandards”, which is supported by SWIFT. To access the messages provided there, users have to complete a one-off registration process.
Additionally, the SWIFT MyStandards Readiness Portal allows institutions to test the messages they have developed for the TARGET2/T2S consolidation project, thereby checking the compatibility of their messages with the message formats described in the UDFS and provided in MyStandards. The SWIFT MyStandards Readiness Portal is available to all participants – regardless of the network service provider through which they will connect to the future platform.
The document "MyStandards + Readiness Portal User Manual" describes the registration process for MyStandards, the functionality of MyStandards Readiness Portal, and certain rules to follow when testing sample messages.
