Merchant ID Registration

A

Cybersource

MID, is a unique value within

Cybersource

that you define during account registration. Your MID identifies your merchant account and payment configuration within

Cybersource

systems. You provide this identifier when you sign in to the

Business Center

and submitting transactions to

Cybersource

.

Multiple MIDs can be configured for various token types. You receive the instrument identifier token regardless of your account’s token type. Reasons for multiple MIDs include:

You have multiple processors.
Point-of-sale terminals have unique MIDs, which are usually configured for the PAN-only instrument identifier token.

When you have multiple MIDs, you can set up one token vault to which all of your MIDs have access or set up multiple vaults to segregate access to tokens. See TMS Vault Management for more information on setting up and managing your token vault.
