# IsRecurring

Matches transactions that are (or are not) part of a recurring series. Shown as "Is recurring transaction" in the condition catalogue.

## Parameters

| Field       | Type   | Required | Allowed values    |
| ----------- | ------ | -------- | ----------------- |
| `recurring` | string | yes      | `"yes"` or `"no"` |

## Example

```json
{
  "constraint": "IsRecurring",
  "params": { "recurring": "yes" }
}
```

## Notes

* **Availability:** might not be included in your platform package — if this condition is missing from the catalogue returned by [List routing constraints](https://documentation.ixopay.com/api/provisioning/list-routing-constraints), contact your Customer Success Manager to have it activated.
* The `recurring` parameter is a string (`"yes"` / `"no"`), not a JSON boolean.
* Available for routing meta-connectors only — not in multi-method routing documents.
