Defining the Merchant ID (MID)

In the payment form, the merchant must specify the value of the Merchant ID (MID).

This feature is used only if you have several MIDs that accept the same currency within the same acceptance network.

Use the optional vads_contracts field to define the Merchant ID (MID) to be used.
  • To define a list of MIDs, separate them with a semi-colon “;”.
    vads_contracts=NETWORK_CODE_A=MID_A1;NETWORK_CODE_B=MID_B2

  • To exclude a network, add network name=NO.
    vads_contracts=NETWORK_CODE_A=NO

  • To force the TID, separate the MID number and the TID number by a colon: “ : ”
    vads_contracts=NETWORK_CODE_A=MID_A1:TID_1

  • If the field is submitted empty, the MID used will be the one defined by the priority order in the Merchant Back Office (Settings > Shop > MID association tab).

Examples:

You have:

  • Two MIDs within the A network: MID_A1 and MID_A2
  • Two MIDs within the B network: MID_B1 and MID_B2

To specify which MID to use for these two networks, vads_contracts must be populated as follows:

vads_contracts=A=MID_A2;B=MID_B1

To offer a payment only for the MID_A1 contract and prevent payments within the B network, populate vads_contracts as follows:

vads_contracts=A=MID_A1;B=NO

In order to force the TID to be used within the A network:

vads_contracts=A=MID_A1:TID_A1
