How can I block a card brand on my campaign?

Card brands (Visa, MasterCard, American Express, Discover and Maestro) are accepted or blocked per MID, not per campaign. Each MID in your load balancer rules has a list of accepted cards, and the load balancer skips any MID that does not accept the customer's card brand. Once none of the MIDs a campaign routes to accept a brand, cards of that brand are rejected before they reach the gateway.

Note: To block only MasterCard, you can also use the campaign's BIN Management tab. Any other brand can only be blocked on the MIDs.

Step 1: Find the Rules Your Campaign Uses

  1. Go to Merchants > Management.

  2. Find the rules that route your campaign's products. Check the Applied Products and Applied Sites columns.

  3. Note every MID in those rules, including the ones in later retry rounds (Round #).

Step 2: Uncheck the Card Brands on Each MID

  1. In the Processor Name column, click the MID name (the one with the pencil icon). The Advanced Processor Settings modal opens.

  1. Under Accepted Card Type Breakdown, uncheck the brands you want to block.

  1. Click Submit.

  2. Repeat for every MID you noted in Step 1.

Important: Make the change on the rules in Merchants > Management. The accepted cards set on a processor in Merchants > Processors are only a default, used when the rule has no card selection of its own. A rule that has its own selection overrides it.

What Happens After the Change

  • An order paid with a blocked brand is not sent to any gateway, and the order returns the error "All processors are either ineligible or have exceeded their daily limits".

  • Cards of the brands that are still checked keep routing to the same MIDs as before.

  • Orders that name a specific MID skip this check and are charged on that MID even with a blocked brand: orders that send a ProcessorID through the API, rebills and upsells that stay on the customer's original MID, and orders run from the Decline Runner.

  • Apple Pay and Google Pay payments are not filtered by card brand.
