+Added

+- New custom field for transaction: `sctm_transaction_refund_for_mollie_payment` which would store the Mollie Payment ID that need to be refunded
+
+Fixes
+
+[Create Refund](./docs/CreateRefund.md)
+- Handling the Refund Creation for the case that the Payment has more than one Success Charge transaction
+  - Changing the way to determine the Create Refund action:
+    - Before
+    ```Typescript
+      // processor/src/utils/paymentAction.utils.ts
+
+      if (groups.successCharge.length === 1 && groups.initialRefund.length) {
+        return ConnectorActions.CreateRefund;
+      }
+    ```
+
+    - After
+    ```Typescript
+      // processor/src/utils/paymentAction.utils.ts
+
+      if (groups.successCharge.length >= 1 && groups.initialRefund.length) {
+        return ConnectorActions.CreateRefund;
+      }
+    ```
+
+  - We are supporting to create the refund for the payment which has more than one Success Charge transactions
+  - By default, we will create the Refund for the latest Success Charge transaction. For example:
+    ```Typescript
+    // CommerceTools Payment
+    {
+      id: 'payment-id',
+      transactions: [
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_123456' // Mollie Payment ID
+        },
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_999999' // Mollie Payment ID
+        },
+        {
+          type: 'Refund',
+          state: 'Initial', // Creating a Refund for the Mollie Payment tr_999999
+        },
+      ]
+    }
+    ```
+
+  - However, you can also specify the Mollie Payment ID (which stored in the `interactionId` of the Success Charge transaction) that you want to create a refund for by adding the Mollie Payment ID to the custom field `sctm_transaction_refund_for_mollie_payment` of the Initial Refund transaction. For example:
+
+    ```Typescript
+    // CommerceTools Payment
+    {
+      id: 'payment-id',
+      transactions: [
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_123456' // Mollie Payment ID
+        },
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_999999' // Mollie Payment ID
+        },
+        {
+          type: 'Refund',
+          state: 'Initial',
+          custom: {
+            type: {
+              ...
+            }, 
+            fields: {
+              sctm_transaction_refund_for_mollie_payment: 'tr_123456' // Creating a Refund for the Mollie Payment tr_123456
+            }
+          }
+        },
+      ]
+    }
+    ```
+
+[Cancel Refund](./docs/CancelPaymentRefund.md)
+- Following the changes for creating refund, we also updated the handler for Refund Cancellation to match with the above changes
+  - Changing the way to determine the Cancel Refund action:
+    - Before
+    ```Typescript
+      // processor/src/utils/paymentAction.utils.ts
+
+      if (
+        groups.successCharge.length === 1 &&
+        groups.pendingRefund.length === 1 &&
+        groups.initialCancelAuthorization.length === 1
+      ) {
+        return ConnectorActions.CancelRefund;
+      }
+    ```
+
+    - After
+    ```Typescript
+      // processor/src/utils/paymentAction.utils.ts
+
+      if (
+        groups.successCharge.length >= 1 &&
+        groups.pendingRefund.length >= 1 &&
+        groups.initialCancelAuthorization.length === 1
+      ) {
+        return ConnectorActions.CancelRefund;
+      }
+    ```
+
+  - To support the old versions, we will create the cancellation for the latest Pending Refund transaction (which is a pending refund for the latest Success Charge transaction in that payment). For example:
+    ```Typescript
+    // CommerceTools Payment
+    {
+      id: 'payment-id',
+      transactions: [
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_123456' // Mollie Payment ID
+        },
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_999999' // Mollie Payment ID
+        },
+        {
+          id: 'refund-transaction-1',
+          type: 'Refund',
+          state: 'Pending',
+          interactionId: 're_123456', // Mollie Refund ID
+        },
+        {
+          id: 'refund-transaction-2',
+          type: 'Refund',
+          state: 'Pending',
+          interactionId: 're_999999', // Mollie Refund ID
+        },
+        {
+          type: 'CancelAuthorization',
+          state: 'Initial'
+          // interactionId is not set
+        }
+      ]
+    }
+
+    // In this case, this will be considered as a Cancellation request for the Pending Refund with id: refund-transaction-2
+    ```
+    __*Note:* The above solution is just for supporting the old versions and will be remove in the near future (in next versions). From this version, please follow the below solution.__
+
+  - However, to do it in a correct way, from this version, you should specify the Mollie Refund ID (which stored in the `interactionId` of the Pending Refund transaction) that you want to cancel by putting it in the `interactionId` of the Initial CancelAuthorization. For example:
+    ```Typescript
+    // CommerceTools Payment
+    {
+      id: 'payment-id',
+      transactions: [
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_123456' // Mollie Payment ID
+        },
+        {
+          type: 'Charge',
+          state: 'Success',
+          interactionId: 'tr_999999' // Mollie Payment ID
+        },
+        {
+          id: 'refund-transaction-1',
+          type: 'Refund',
+          state: 'Pending',
+          interactionId: 're_123456', // Mollie Refund ID
+        },
+        {
+          id: 'refund-transaction-2',
+          type: 'Refund',
+          state: 'Pending',
+          interactionId: 're_999999', // Mollie Refund ID
+        },
+        {
+          type: 'CancelAuthorization',
+          state: 'Initial',
+          interactionId: 're_123456' // Mollie Refund ID that you want to cancel
+        }
+      ]
+    }
+
+    // In this case, this will be considered as a Cancellation request for the Pending Refund with id: refund-transaction-1 
+    ```
