In troubleshooting efforts when SWP request messages are signed, we often find it is necessary to look for more details in the following elements --

1. Exact URL where SWP request messages are being sent
2. Exact SWP request message being sent to the URL referenced above
3. Exact message string being encrypted using an HMACMD5(..) compatible algorithm
4. Merchant ID
5. External IP address of server submitting the SWP request message
6. Exact SWP response message when difficulties are experienced

If  troubleshooting assistance is needed, please forward these elements (with sensitive values masked such as account numbers, passwords, etc..)  to integration@paymentsgateway.com along with a description of the issue for review.
