Use `client.Reconciliation.UpdateMatchingRule` to update a matching rule.
```go client.Reconciliation.UpdateMatchingRule theme={"system"}
updatedRule, resp, err := client.Reconciliation.UpdateMatchingRule(
"rule_890bdbc4-467f-4670",
blnkgo.Matcher{
Name: "Amount match (updated)",
Description: "Match by amount with 2% drift",
Criteria: []blnkgo.Criteria{
{
Field: blnkgo.CriteriaFieldAmount,
Operator: blnkgo.ReconciliationOperatorEquals,
AllowableDrift: 0.02,
},
{
Field: blnkgo.CriteriaFieldCurrency,
Operator: blnkgo.ReconciliationOperatorEquals,
},
},
},
)
```
| Field | Type | Description |
| :-------------------------- | :------------------------------ | :-------------------------------------------------------------------------------------------------------------------------------------------- |
| `ruleID` | `string` | ID of the matching rule to update. |
| `Name` | `string` | Updated name for the rule. |
| `Description` | `string` | Updated description of what the rule does. |
| `Criteria` | `[]blnkgo.Criteria` | Full replacement array of match criteria. |
| `Criteria[].Field` | `blnkgo.CriteriaField` | Field to match: `CriteriaFieldAmount`, `CriteriaFieldCurrency`, `CriteriaFieldReference`, `CriteriaFieldDescription`, or `CriteriaFieldDate`. |
| `Criteria[].Operator` | `blnkgo.ReconciliationOperator` | How to compare the field: `ReconciliationOperatorEquals` or `ReconciliationOperatorContains`. |
| `Criteria[].AllowableDrift` | `float64` | Optional tolerance for `amount` (percentage) or `date` (seconds). |
Read fields on the returned `*blnkgo.RunReconResp` to confirm the updated criteria and description. The rule ID stays the same.
