# MID Groups

> Learn how to create and manage MID Groups in Paysight to optimize payment routing, approvals and business flexibility.

Paysight’s **MID Groups** feature lets you combine multiple Merchant IDs (MIDs) into a single routing pool. This helps optimize transaction approval rates, distribute volume across processors, provide automatic failover and meet regional or product based requirements. The configuration happens in one place, making updates easy as your business grows.

***

## What Are MID Groups?

A **MID Group** is a set of MIDs that you bundle together with custom logic. Paysight routes transactions across these MIDs to help maximize success, meet compliance needs and increase flexibility, without manual switching.

**Key Benefits:**

* Higher approval rates by routing transactions to the best-performing MID for the card type, region, or other rules.
* Built-in failover. If one MID is down or declines the transaction, Paysight immediately tries the next.
* Easier scaling since you can add or change MIDs in a group without major disruptions.
* Control over routing logic, such as geolocation, currency, risk profile, or product.

***

## Common Use Cases

* Merchants processing high volumes with more than one processor.
* International businesses needing to route payments based on region.
* Businesses aiming for maximum uptime during processor outages or card type restrictions.
* Performance testing by sending a percentage of transactions to a new MID.

## How to Create a MID Group

<Steps>
  <Step title="Open the MID Groups Section">
    1. Go to [Paysight Dashboard](https://app.paysight.io/).
    2. Navigate to `MID Management` > `MID Groups`.
  </Step>

  <Step title="Create and Name Your Group">
    1. Click `Add Routing Group`.
    2. Choose which routing types you want to use and click `Create`.

           <Note>
             **The 2 Routing Group Types**: <br />
             Manual Routing Group:

             * You have control to weight each added MID accounts.
             * Useful for routing transactions to a specific set of merchants.
             * Weighting ranges from 0 to 100, it determines the percentage of transactions that will be routed to the merchant.

             Automatic Routing Group:

             * Once multiple MID accounts has been added, it will automatically weight the merchants based on their current remaining capacity.
             * Useful and recommended, if you want to route transactions to a specific set of merchants, but want automated weighting based on their current remaining capacity.
             * A bias multiplier can be set to increase or decrease the weight relative to the other merchants.
           </Note>
    3. Name the group and click `Create` to continue.
  </Step>

  <Step title="Add MIDs to the Group">
    1. Once the group has been created, you can click `Add Merchant Account` and choose a MID.
           <Note>
             Ensure that those MID accounts have been tested by your account manager and ready to set live first. Then you can add that MID account once it is set live.
           </Note>
    2. Set their order if you want priority routing. Drag to change sequence.

           <Note>
             Manual Routing Group:

             * It is recommended to prioritize the bigger capped MID accounts, if multiple MIDs are weighted in order based from their cap, they will sequentially move to another MID to make a transaction once the bigger MID failed.

             Automatic Routing Group:

             * The weight will be a bias multiplier can be increased or decreased, relative to the other merchant.
           </Note>
  </Step>

  <Step title="Configure Options">
    * Once a MID Group is set up, change the billing configurations in Subscriptions and Products.
    * Monitor the performance of each MIDs once they are set up.
    * If a MID or multiple MID accounts have been disabled, inform your account manager to check that MID account.

    <Warning>
      **If there is an inactive MID account**:

      * If a MID account is disabled due to cap being reached or manually paused, you do not need to remove it from the group.
      * It will automatically not be available for selection within the group, once it is active again, it will automatically be available within the group.
      * This keeps maintenance to a minimum, without the need to swap MID accounts, in and out
    </Warning>
  </Step>
</Steps>

<Tip>
  You can edit a MID Group at any time. Changes take effect immediately for all future transactions routed through the group.
