400 Bad Request errors 29 July 2025
Getting 400 Bad request errors on differing tables and different entities when trying to retrieve data today.
Forum Discussion
Hi SatoriFPA,
The "400 - Bad request" error usually means the invoice data sent to MYOB doesn't meet API requirements. To investigate, MYOB needs the API call's header and body details, which you generally can’t access or retrieve from your computer. You may send a support request to our MYOB API Team using this link to sort this out.

i have exactly the same issue and it started on the same date. It would seem that something on the MYOB server side has changed which has started this problem. This same API call has worked daily without issue for the past 2 years.
Hi mcdonaldaj,
Thanks for jumping in. The best way to get it sorted is to submit a support request using the link one of our mods popped into thread earlier. That way they can take a proper look under the hood for you.
Regards,
Sai
