When it is `false`, no installer is offered and `url` returns `404`. See [Pairing a device](/guides/byod#pairing-a-device). * **Links:** `url` is a stable link that redirects to the installer. `POST /v1/byod/pair` returns the same links in `download_urls`. * **Versions:** `version` is not `null` exactly when `version_status` is `published`: see [Versions of the bridge app](/guides/byod#versions-of-the-bridge-app). ## Errors This operation has no error of its own. The errors that every operation shares are in [Errors](/errors-and-rate-limits#errors). ## OpenAPI ````yaml GET /v1/apps openapi: 3.0.0 info: title: iSnap API version: 2.45.0 description: >- The iSnap API sends and receives iMessage, RCS and SMS on real phone lines, manages those lines, and reports events through webhooks. Every message is sent to a real recipient, with an `isnap_live_` key and with an `isnap_test_` key alike. Retry a `429` after `Retry-After` seconds. Retry a `500` or a `503` up to 2 times, with exponential backoff. Do not retry any other `4xx`: fix the request. Retry a write only on an operation that honors `Idempotency-Key`, with the key of the first attempt. Responses carry personal data: handles, names and message text. servers: - url: https://api.isnap.ai security: - bearerAuth: [] paths: /v1/apps: get: summary: Get the bridge app downloads description: >- Returns, for macOS and for Android, the download link and the published version of the bridge app that a BYOD device runs: the bridge app for macOS on a Mac, the bridge app for Android on an Android phone.
