# Delete Migration Split

> Remove a pathway's migration split so all its traffic runs on the pathway.

Removes the migration split from a V1 pathway. From the next call, all of the pathway's traffic runs on the pathway. A rollout over the split never blocks this request, and the rollout ends. The request succeeds even when the pathway has no split.

Delete the split before you attach the pathway's numbers to an agent or a persona: while a split exists, even at `0%`, [Attach Numbers to Agent](https://docs.bland.ai/api-v2/post/agents-id-inbound-attach.md) and [Attach Phone Numbers to Persona](https://docs.bland.ai/api-v1/post/personas-id-inbound-attach.md) return `409 MIGRATION_EXPERIMENT_NUMBER` for those numbers. To keep the split but send no traffic, use [Set Migration Split](https://docs.bland.ai/api-v1/put/convo-pathway-id-migration-split.md) with `v2_percentage` set to `0`.

Requires an admin, owner, or operator role.

### Headers

**authorization** `string` *required*

Your API key for authentication.

### Path Parameters

**pathway\_id** `string` *required*

The V1 pathway. Must be a UUID of a pathway in your organization. Returns `400 BAD_REQUEST` for an invalid UUID, `404 NOT_FOUND` for a pathway outside your organization, and `400 BAD_REQUEST` for a pathway that Bland compiled from a V2 agent.

### Response

**data.deleted** `boolean`

Always `true` on success.

**errors** `null | array`

`null` on success, or a list of error objects if the request failed.

```json Response theme={null}
{
  "data": {
    "deleted": true
  },
  "errors": null
}
```

```json Pathway Not Found theme={null}
{
  "data": null,
  "errors": [
    {
      "error": "NOT_FOUND",
      "message": "Pathway not found"
    }
  ]
}
```
