# Edit a connected account's own profile

`PATCH /v1/social-accounts/{id}/profile`

Change the display name, bio, avatar or banner. Only the fields you send are changed. Images are given as public URLs and uploaded for you. A network that does not allow this refuses.

## Request

Authenticate with a bearer API key. Agents calling over MCP authorise with OAuth instead and never handle the key.

```bash
curl -X PATCH https://api.postlake.dev/v1/social-accounts/{id}/profile \
  -H "Authorization: Bearer $POSTLAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"displayName":"…","bio":"…","avatarUrl":"…","bannerUrl":"…"}'
```

### Parameters

| Field | Type | Required | What it is |
| --- | --- | --- | --- |
| `id` | string | Yes | In the URL. |

### Body

| Field | Type | Required | What it is |
| --- | --- | --- | --- |
| `displayName` | string | No |  |
| `bio` | string | No |  |
| `avatarUrl` | string | No |  |
| `bannerUrl` | string | No |  |


## Response

Updated (`200`).

| Field | Type | Required | What it is |
| --- | --- | --- | --- |
| `account` | string | No |  |
| `platform` | string | No |  |
| `ok` | boolean | No |  |



### Example

```json
{
  "account": "…",
  "platform": "…",
  "ok": false
}
```


## Calling this from an agent

Agents do not call REST. They call tools. Over the hosted MCP server this operation is `list_social_accounts`, and the agent authorises with OAuth so your API key is never pasted into a chat or seen by the model. You control what any one agent may do: which brands it may act for, which networks it may reach, how much a day, and whether it may spend credits bought up front.

## Errors

Every failure uses one shape: a stable `type`, a granular `code`, the field at fault in `param`, and a plain-language `fix`. See https://docs.postlake.dev/errors.md .

Retries are safe: send the same `Idempotency-Key` and a call that already succeeded returns its original result rather than repeating it.

## Common questions

**Can an AI agent do this without the REST API?**

Yes. Over MCP the same job is the list_social_accounts tool. The agent authorises with OAuth, so no API key is pasted into a chat or seen by the model, and the answer comes back in the same normalised shape.

**Is it safe to retry this call?**

Yes. Send the same Idempotency-Key and a call that already succeeded returns its original result instead of repeating the work. That is what makes it safe to hand to an agent that retries on its own.

**What happens when it fails?**

You get one error shape: a stable type, a granular code you can branch on, the offending field in param, and a fix written so an agent can correct itself rather than stop. Full list on Errors and retries.
