'Either Action or Operation query parameter must be present


#1

Everything was fine for years, but today I started getting this error
{ Type: ‘Sender’,
Code: ‘InvalidParameterValue’,
Message:
‘Either Action or Operation query parameter must be present.’,
Headers:
{ ‘x-mws-quota-max’: ‘unknown’,
‘x-mws-quota-remaining’: ‘unknown’,
‘x-mws-quota-resetson’: ‘unknown’,
‘x-mws-timestamp’: ‘2020-05-28T21:14:33.425Z’,
‘content-type’: ‘text/xml’,
‘content-charset’: ‘unknown’,
‘content-length’: ‘324’,
‘content-md5’: ‘unknown’,
date: ‘Thu, 28 May 2020 21:14:33 GMT’ },
StatusCode: 503,
RequestId: ‘…’ }

I’m requesting GetMatchingProductForId.
Is anyone else getting those errors?

Hi,
The Products API is having issues and Amazon is aware of it. You can see the status at http://status.mws.amazon.com/ .
