## Get Self Mailer Preview

**get** `/print-mail/v1/self_mailers/{id}/url`

Retrieve a self-mailer preview URL.

This is only available for customers with our document management addon, which offers
document generation and hosting capabilities. This endpoint has a much higher rate limit
than the regular order retrieval endpoint, so it is suitable for customer-facing use-cases.

### Path Parameters

- `id: string`

### Returns

- `id: string`

  A unique ID prefixed with self_mailer_

- `object: string`

- `url: string`

  A signed URL linking to the order preview PDF. The link remains valid for 15 minutes from the time of the API call.

### Example

```http
curl https://api.postgrid.com/print-mail/v1/self_mailers/$ID/url \
    -H "X-API-Key: $POSTGRID_PRINT_MAIL_API_KEY"
```

#### Response
