On 27 October 2023, TOTSCo circulated the One Touch Switch Developers Guide V.0.3 for review by industry. This is an update to version v.0.0.1, which was released on 31st October 2022. The API specification has been updated to reflect reviews and comments since its initial publication. We welcome comments on these draft documents, and will consider these before finalising the documents for publication and placing them under formal change control.

Our preferred format for review comments is inline comments within the Word Document itself – please find the document on our Resources page. We would appreciate each CP sending only one document with review comments as this will speed up the review process. Please submit feedback by Friday 17 February, 2023 by email to enquiries@totsco.org.uk.
