Response code 01 (Invalid Request)

This data is not used as part of the transaction processing, but a record of the data is kept with the transaction. This can be of use should a customer dispute a transaction, providing additional details of where the device was when the transaction was processed.

There are many possible causes of the ‘Invalid Request’ response. In order to help maintain system security the exact cause is not contained with the response. For example the reason could be that the request has been received from an un-authorised IP address, or that the password used is not correct. This information is not divulged as part of the response data, you will need to view the exception report to see the full details.

A common cause of this error is attempting to use the mobile API without first requesting that it is added to your account. You must first request that the mobile API is added to your account before you start to use it – this is not enabled by default. As part of the activation process you will be supplied with the authentication key.
