Multi MID

Multi Merchant IDs (MMID) allows businesses operating under a single payment terminal to route transactions to different Merchant IDs (MIDs), each associated with a specific business entity, department, or service category. This is especially useful for environments like salons, medical offices, or multi-brand retail locations where different revenue streams must be tracked and settled separately.

In the iPOSpays environment, each MID is tied to a specific TPN (Terminal Provider Number). When MMID is enabled:

• The TPN tag must contain the Master TPN, which represents the primary terminal setup.
• The MerchantId tag must contain the transacting TPN, which determines the MID under which the transaction should be processed.

Sample MerchantId tag

<MerchantId>123456789143</MerchantId> <MerchantId>123456789143</MerchantId>
