The company file version is not supported

[Shane_Russell]

I am connecting to the MYOB API using Postman and am able to authenticate and List company files and API info.  I can also query a single file by Company_File_URI and Company_FIle_Id to successfully list all the API endpoints.

However, if I attempt to query any of the end points I receive an error:   {"Message": "The Company File version is not supported."}

Company_FIle_URI is https://arl2.api.myob.com/accountright/

https://arl.api.myob.com/accountright/info reports V2 for all endpoints.

I am passing v2 as x-myobapi-version

I am not sure how to proceed.

Just checking, but yourCompany_FIle_URI should have a UID at the end:
https://arl2.api.myob.com/accountright/<UID>

And have you created the token using the username and password?

[Shane_Russell]

Yes I am using Company_File_URI/Company_File_ID

Yes I have created the token.

OK, I thought that might be the case but just checking.

I have had this issue once before, and that was when I created a new MYOB business using the website instead of using the AccountRight desktop software. Using the website (I am not sure exactly where I was because MYOB has so many different domains that I get lost) it must have created a type of Company File that was unable to be accessed using this particular API. IIRC I was able to make some of the initial requests but then got denied with the same error message you are getting when trying to go further.

Once I installed the actual AccountRight software in a virtual machine, and created a business there, I was able to use the API and complete my integration.

This might not be your issue, but do check your account type to make sure it is a compatible MYOB product, which are alluded to here:
