MIDs

A Merchant ID (MID) identifies the merchant account used to process a payment with a payment service provider (PSP).

In Revup, a MID represents a configured connection between Revup and a PSP. This allows Revup to route transactions to the appropriate payment processor.

How MIDs work​

When a payment is processed through Revup, the transaction is associated with a Revup MID.

The Revup MID is connected to a PSP MID, which identifies the merchant account at the payment service provider.

The relationship can be represented as:

The PSP MID is configured in Revup and is used to process transactions through the corresponding payment provider.

Revup MID and PSP MID​

Revup distinguishes between the MID used within the Revup platform and the MID configured with the payment service provider.

MIDDescription
Revup MIDIdentifies the merchant processing configuration within Revup.
PSP MIDIdentifies the merchant account at the payment service provider.

A Revup MID is associated with a PSP MID so that Revup knows where and how to route the transaction.

Multiple MIDs​

A merchant can have multiple MIDs configured in Revup.

Multiple MIDs can be useful when a merchant:

  • Works with more than one payment service provider.
  • Uses different processing configurations.
  • Needs to route payments according to different business requirements.
  • Uses a different processing setup for specific payment flows.

The exact routing configuration depends on the merchant's Revup setup.

MID routing​

When multiple MIDs are available, Revup can use the configured routing rules to determine which MID should process a transaction.

The routing configuration is managed in Revup and determines how transactions are assigned to the available processing configurations.

Your integration does not normally need to select a PSP MID directly when creating a payment. Instead, Revup uses the configured MID and routing setup to determine the appropriate processing path.

info

MID routing is configured in Revup. Contact your Revup team if you need to configure or change the MIDs available for your account.

MIDs and payment transactions​

A MID is associated with the transaction that processes the payment.

This is useful when reviewing transaction information because the MID identifies the processing configuration used for that transaction.

When troubleshooting payment processing, the MID can therefore help identify which processing route was used.

MIDs and fallback processing​

Revup can also be configured with a Fallback MID.

A Fallback MID provides an alternative processing route that can be used when the primary MID cannot successfully process a transaction.

Fallback processing is separate from the general MID configuration described on this page.

For more information, see Fallback MID.

Configuring MIDs​

MIDs are configured as part of your Revup account and payment processing setup.

The configuration may include:

  • The Revup MID.
  • The associated PSP MID.
  • The payment service provider.
  • The processing configuration.
  • Routing rules.

The available configuration depends on your Revup account and PSP setup.

If you need to configure a new MID or modify an existing MID, contact your Revup team.
