Why do I get the error "This transaction cannot be accepted" during checkout of MyGreenCart when using Authorize.Net as the payment gateway?

The most populars errors for Authorize.Net are as follows:

3.1.103 - This transaction cannot be accepted.
Authorize.Net returns "3,1,103,This transaction cannot be accepted". It means that the transaction key or password is required for this transaction. The problem occurred because MyGreenCart didn't send the the correct Authorize.Net API Login and Transaction Key. Please contact Authorize.Net for the API Login and Transaction Key. Then login to the MyGreenCart Admin area, click Payments, then Edit Payment Options. Then click the modify icon for Authorize.Net and enter the API Login and Transaction Key, then click save/update.
This error can also occur because MyGreenCart doesn't send the Authorize.Net account password in the transaction for the security reasons, but this Authorize.Net account requires the password in each transaction. Since this requirement is set for this Authorize.Net account in its settings, you must login or contact Authorize.Net to turn this off in your account with them.

3.1.97 - This transaction cannot be accepted.
Authorize.Net returns "Response 3,1,97,This transaction cannot be accepted". This means the time on server is not synchronized. The Authorize.net will error out even if 1 minute of difference come up. Please contact us to fix this.

3.1.99 - This transaction cannot be accepted.
Authorize.Net returns "3,1,99,This transaction cannot be accepted". This mean that you are using incorrect Transaction Key in your Merchant Gateway settings in the MyGreenCart admin area. Please contact Authorize.Net for the API Login and Transaction Key. Then login to the MyGreenCart Admin area, click Payments, then Edit Payment Options. Then click the modify icon for Authorize.Net and enter the API Login and Transaction Key, then click save/update.
