# Detach a patient from a subscriber [#detach-a-patient-from-a-subscriber]

| Method | Path |
| --- | --- |
| `DELETE` | `/v1/signals/api/subscriber/{id}/patients/{patientId}` |

<Availability route="DELETE /v1/signals/api/subscriber/{id}/patients/{patientId}" />

The subscriber no longer reads the patient's records or receives its alerts.

### Through ovok [#through-ovok]

- **Who can call it:** Manager apps, and users whose access policy grants the capabilities.
- **Capabilities, all required:** `signals_associations:update`. Project admins have every capability; client applications get no admin bypass.
- If your access covers only some patients (anyone but project admins, manager or submitter apps, and anyone whose Patient access has no criteria), the patient must be one you can update. A patient is named by its Signals id, or by its Medplum Patient id where Signals takes a `refId`; ovok asks Signals which patient a Signals id is.

## Request [#request]

### Path parameters [#path-parameters]

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | Yes | The client's `clientId`: the value a patient's `submitters`/`subscribers` hold. |
| `patientId` | string | Yes | The Signals patient id. |

## Responses [#responses]

| Status | Meaning |
| --- | --- |
| `200` | The pair that was detached. |
| `400` | A path value holds a character ovok does not send to Signals, such as a raw `:` or `+`. Percent-encode it. The query carries a raw `#`, or more than 200 parameters. |
| `401` | Your ovok access token, or your client id and secret, are missing or invalid. |
| `403` | ovok refused the call: you lack a capability this route needs, or your session has no project, or you can read a patient the call names but not update it. From Signals: Authenticated, but the client's role does not permit this, or it is not attached to the patient. |
| `404` | A patient the call names is not one you can read. From Signals: The subscriber was not attached to that patient. |
| `409` | Your project has no Signals tenant of its own (`SIGNALS_TENANT_NOT_OWN`), or it is moving to another one. |
| `422` | A patient id is not 1 to 64 letters, digits, `.`, `_`, `~` or `-`. |
| `429` | Too many requests. Retry after the seconds in `Retry-After`. |
| `500` | ovok hit an unexpected fault, such as your project having no Signals submitter. |
| `502` | Signals answered with something ovok couldn't use, or refused ovok's own credential. |
| `503` | Signals is unavailable. Retry after the seconds in `Retry-After`. |
| `504` | Signals did not answer in time. |
