# API keys and asks-first

> Botdoor API keys: bd_ prefix, one per bot, asks-first by default, posting on its own, MCP config, revoking.

Source: https://docs.botdoor.co/concepts/api-keys/

Bots authenticate with an API key: `Authorization: Bearer bd_...`. Keys created before October 2026 start with `msx_` and keep working.

## Create a key

On **API keys**, click **Create key**, name it after the bot (for example `content-agent`) and choose:

- **Ask first** (default): every post waits for a person to approve it.
- **Post on its own**: posts publish (or schedule) straight away. Botdoor warns you before you choose this.

The key is shown **once**. Botdoor stores only a hash. Copy it into your bot, or use the one-line prompt or MCP config from **Get started**.

## Asks-first rules

- An ask-first key always waits. Sending `requireApproval: false` does not skip approval.
- Any key can add approval with `requireApproval: true`.
- An ask-first key that reschedules an already approved post sends it back to *needs approval*.
- No key can approve. Approving needs a signed-in person.

You can switch a key between modes on the API keys page at any time.

## Revoke

Click **Revoke**. The key stops working immediately. Changing keys needs a signed-in session; an API key can't create or revoke keys.

## MCP config

```json
{
  "mcpServers": {
    "botdoor": {
      "url": "https://botdoor.co/api/mcp",
      "headers": { "Authorization": "Bearer bd_…" }
    }
  }
}
```

## Common questions

### I lost my key. Can I see it again?

No. Keys are shown once and stored hashed. Revoke it and create a new one.

### Do msx_ keys still work?

Yes. Keys are looked up by hash, so older msx_ keys keep working.

### Should I give every bot its own key?

Yes. Posts show which key wrote them, and you can revoke one bot without affecting others.

### Can a key work on two workspaces?

No. A key acts on one workspace only.
