Fix for MYOB Cloud Authentication Issue

If you are experiencing issues authenticating with MYOB Cloud as a result of changes made by MYOB in mid August 2024 please follow the steps below to modify your fmAccounting Link (MYOB AccountRight Edition) v1 solution/integration to be compatible with the updates made by MYOB.

You can find the instructions for fmAccounting Link (MYOB AccountRight Edition) v2 here.

1 - Change the Redirect URL

Please enter the following URL in the Redirect URL field on the MYOB COMPANY screen as highlighted above:

https://www.databuzz.com.au

The previous default value for the Redirect URL field - http://desktop - no longer works with the changes made by MYOB. Make sure you copy/paste the URL exactly as it appears above - you will get an error about an invalid redirect URL if you do not enter this exactly as it appears above.

2 - myobAuth script changes

You will need to make a number of small changes to the myobAuth script as a result of the change to the Redirect URL above.

2.1 - change the calculation formula for the $htmlContent Set Variable step to:

GetLayoutObjectAttribute ( "myobAuthWebViewer" ; "source" )

2.2 - change the test for the code= parameter to:

not PatternCount ( $htmlContent ; "code=" )

2.3 - change the calculation formula for the $code Set Variable step to:

Let ( [ 
	t1 = GetLayoutObjectAttribute ( "myobAuthWebViewer" ; "source" )  ; 
	n1 = Position ( t1 ; "code=" ; 1 ; 1 ) ;
	n2 = Position ( t1 ; "&scope=" ; 1 ; 1 ) ;

	t2 = Middle ( t1 ; n1 + 5 ; n2 - n1 - 5 ) 
] ; 

t2

) // Let

Save the script changes - you should now be able to successfully authenticate with the MYOB API using the FileMaker Web Viewer again.
