# Read post destinations

`social.destinations.read@1`

Checks that the accounts you chose can take a text-only post and tells you each platform's limits, so you can write before anything is saved. With `incompatible` set to `report` it lists the accounts that cannot instead of refusing the call. It reads and changes nothing. It needs a key with **Read social**.

## Check an account

Send the account's row reference, as its row gives it.

## Parameters

What goes in `input`:

| Name | Type | Required | Description |
|---|---|---|---|
| `accountRefs` | array of object | Yes | The accounts to check, 1 to 10; one listed twice is refused. |
| `accountRefs[].businessProfileId` | string | Yes | Your business's id. |
| `accountRefs[].featureId` | string | Yes | The `featureId` of the account's row. |
| `accountRefs[].collectionId` | string | Yes | The `collectionId` of the account's row. |
| `accountRefs[].id` | string | Yes | The account's id. |
| `format` | `post` | Yes | Always `post`: only plain posts can be checked here. |
| `mediaKind` | `none` | Yes | Always `none`: the post carries no photos or video. |
| `incompatible` | one of `refuse`, `report` | No | `refuse` (the default) rejects the call when an account cannot take the post; `report` answers with the accounts that can in `destinations` and the ones that cannot in `incompatible`, each with the reason. |

## Response

A call that worked answers `200` with an `applied` receipt; its `output` holds these fields, among others. `GET /catalog/social.destinations.read@1` answers the complete shape as JSON Schema.

| Name | Type | Description |
|---|---|---|
| `destinations` | array of object | The accounts that can take the post, in the order you asked. Empty only when `incompatible` is sent and no account can. |
| `destinations[].accountRef` | object | The account. |
| `destinations[].platform` | one of `facebook`, `instagram`, `linkedin`, `x`, `tiktok`, `youtube`, `pinterest`, `threads`, `bluesky` | Its platform. |
| `destinations[].label` | string | The account's name. |
| `destinations[].constraints` | object | What the platform allows. |
| `destinations[].constraints.captionLimit` | integer | The longest caption, in characters. |
| `destinations[].constraints.formats` | array of one of `post`, `story`, `reel` | The formats it takes: `post`, `story`, `reel`. |
| `destinations[].constraints.options` | array of one of `altText`, `link`, `firstComment`, `title`, `privacy`, `shareToFeed`, `collaborators`, `allowComments`, `allowDuet`, `allowStitch`, `discloseBrand`, `brandedContent`, `aiGenerated`, `madeForKids`, `replySettings` | The extra settings a post can carry there, such as `link` or `altText`. |
| `destinations[].constraints.optionChoices` | object | The values allowed for `privacy` and `replySettings`, where they are limited. |
| `destinations[].constraints.mediaRequired` | boolean | Whether a post must have a photo or video. |
| `destinations[].constraints.maxMedia` | integer | The most photos or videos a post can carry. |
| `destinations[].constraints.mediaTypes` | array of string | The kinds of file it takes. |
| `incompatible` | array of object | Only with `incompatible` `report`: the accounts that cannot take the post, in the order you asked, each with its `accountRef`, `platform` and a `reason` in plain words. |

## Errors

It reads and changes nothing. Besides the answers every request can get ([Errors](../errors.md)), its receipt can say:

| Status | HTTP | What it means |
|---|---|---|
| `rejected` | 400, or 403 when it's a matter of access | Not done. `diagnostics` says why: each has a `code`, a `path` into what you sent and a `message`. |

The codes in `diagnostics` you're most likely to see:

| Code | Status | What it means |
|---|---|---|
| `DATA.ROW_NOT_FOUND` | `rejected` | No such account here for this key. |
| `SOCIAL.ACCOUNT_DUPLICATE` | `rejected` | An account is listed twice. |
| `SOCIAL.PLATFORM_UNSUPPORTED` | `rejected` | An account's platform cannot be published to. Not raised with `incompatible` `report`. |
| `SOCIAL.MEDIA_REQUIRED` | `rejected` | An account's platform needs a photo or video, so it cannot take a text-only post. Not raised with `incompatible` `report`. |
