After you understand the complexities of payment routing by item (see How do I route all transactions with a specific item to a relationship?), you are ready to set it up.
To set up payment routing by item
Work with Integrations Support to set up your Nexio account and merchant accounts (MIDs) so that they are optimized for payment routing by item.
In general, this means having a single API user with a MID that contains the specific relationship (merchant account provider, processor, or acquirer/bank) that applies for the item routing as well as one or more additional relationships for cases where that item is not in the request.
Navigate to Settings > Payment Routing.
The tab shows user accounts and the types of rules.
Locate the user account that you want to add to or modify item routing rules for. Click that row in the table.
The Payment Routing Rules page displays.
Click Add New Rule.
The Add Routing Rule dialog displays.
Select Item Routing as the rule type and then select the MID you want to add this rule to.
For example, select MID #1.
Specify one or more attributes for the item routing rule.
For example, if you have a CBD item in your catalog (where
data.cart.items[n].itemcontains the text 'CBD') and want to route any transactions with that item to a specific gateway that is associated with MID #1, do the following:
Example Rule 1a:
If `Item` `Contains` `CBD`
You may also want to add a second rule in case the text is lowercase:
Example Rule 1b:
If `Item` `Contains` `cbd`
Alternately, you can create only one rule if you use a regular expression that matches on the letters "cbd" in the item, regardless of the case of any of the letters, such as the following:
Example Rule 2:
If `Item` `RegEx(ECMAScript)` `[c|C][b|B][d|D]`
You can then add more attributes if you want. For a rule with multiple attributes, the system only matches when ALL the specified attributes match.
When you are done creating the rule, click Save.
For the transaction request, configure the API as follows.
Each payment request must include the following parameters for item routing:
