It is time to say goodbye to version1 of AccountRight API.
Version 2 of AccountRight API was introduced in Aug 2013, and we have been encouraging any development to be done on this basis.
As of 9th of April 2020*¹, any connection to version 1 of AccountRight API via online AccountRight API on Add-on Connector and AccountRight server edition will result in an error. Desktop AccountRight API connection remains active post 2nd of March 2020, but decommissioning will also be scheduled in a close future release.
To be prepared for this change, please review your Header(or Parameter) and ensure x-myobapi-version: v2 is consumed. For more version 2 instruction visit here, and ensure connections are to be made to corresponding endpoints.
*¹ Updated on 28/02/2020 - Decommission date has been pushed out to ensure we allow our developers
to have enough preparation period.
