# Start reconnecting an account

> Page: https://docs.flung.dev/reference/api/post-v1-accounts-id-reconnect. Index of every page: https://docs.flung.dev/llms.txt

For an account that is `needs_reconnect` or `disconnected`.

`POST /v1/accounts/{id}/reconnect`

## TL;DR

| Question | Answer |
|---|---|
| What does it do? | Start reconnecting an account. |
| What does it need? | An API key, an OAuth access token, or a connect token (this is one of the calls a connect token may make). |
| What does it take? | A JSON body with the fields below, and `id` in the path. |
| What does it return? | Status 201 with a body of type [`ConnectSession`](https://docs.flung.dev/reference/api/schemas.md#connectsession). |
| In the SDK? | `flung.accounts.reconnect()` |
| As an MCP tool? | [`reconnect_account`](https://docs.flung.dev/reference/mcp/reconnect-account.md) |
| What can go wrong? | `401` Missing, unknown, revoked or expired API key; `404` No such account in this workspace; `422` The request failed validation; `429` Too many requests for this credential; wait for `retry-after` seconds. Every failure has the same [error shape](https://docs.flung.dev/reference/api/errors.md). |

## What it does

For an account that is `needs_reconnect` or `disconnected`. The person must sign in as the same platform user; another user is refused.

## Example

**curl**

```bash
curl -X POST 'https://api.flung.dev/v1/accounts/acct_aaaaaaaaaaaaaaaaaaaaaaaa/reconnect' \
  --header "Authorization: Bearer $FLUNG_API_KEY" \
  --header 'Content-Type: application/json' \
  --header "Idempotency-Key: $(uuidgen)" \
  --data '{
  "redirectUrl": "https://app.example.com/settings/social"
}'
```

**TypeScript**

```ts
import { Flung } from '@flung.dev/sdk'

const flung = new Flung({ apiKey: process.env.FLUNG_API_KEY! })
const result = await flung.accounts.reconnect({
  id: 'acct_aaaaaaaaaaaaaaaaaaaaaaaa',
  redirectUrl: 'https://app.example.com/settings/social',
})
```

**fetch**

```js
const response = await fetch('https://api.flung.dev/v1/accounts/acct_aaaaaaaaaaaaaaaaaaaaaaaa/reconnect', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${process.env.FLUNG_API_KEY}`,
    'Content-Type': 'application/json',
    'Idempotency-Key': crypto.randomUUID(),
  },
  body: JSON.stringify({
    redirectUrl: 'https://app.example.com/settings/social',
  }),
})
if (!response.ok) throw new Error((await response.json()).error.message)
const result = await response.json()
```

A successful answer looks like this:

```json
{
  "id": "cs_aaaaaaaaaaaaaaaaaaaaaaaa",
  "platform": "x",
  "accountId": "string",
  "status": "pending",
  "authorizationUrl": "https://example.com",
  "expiresAt": "2026-11-01T09:00:00.000Z",
  "accountIds": [
    "string"
  ],
  "error": {
    "code": "string",
    "message": "string"
  },
  "createdAt": "2026-11-01T09:00:00.000Z",
  "completedAt": "2026-11-01T09:00:00.000Z"
}
```
