Unable to authorise MTD

Posted on by laura_bowie 5

Hi All

When trying to setup the HMRC VAT Setup for a new company on BC we get to the point where you can give permission on the HMRC site but instead of popping up a window saying authorisation granted and the authorisation code the entire tab disappears and we are brought back to the main service connections page in BC

Has anyone else encountered this and if so how was it resolved? My client needs this setup so they can submit their VAT online for MTD purposes as in the UK.

it is on this screen and we are trying to request the authorisation code

    Update: There is an issue with the Redirect URL and it needs to be changed to urn:ietf:wg:oauth:2.0:oob and this will prevent this issue happening
