> Creates a Meeting Type.

Create makes a new [Meeting Type](/business/nouns/meeting-type) from the inputs below. It is inherited: every [Noun](/business/nouns/noun) has `get`, `list`, `create`, `update` and `delete`.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `name` | `string` | Yes | What the booking page calls it, such as `Intro call`. |
| `duration` | `integer` | Yes | Minutes each Meeting runs. |
| `medium` | `string` | Yes | How people meet: `video`, `phone` or `inPerson`. |
| `availability` | [Availability](/business/nouns/availability) | Yes | The hours it books into. |
| `url` | `url` | No | The booking link, served on the Startup’s Domain once published. |
| `questions` | `string[]` | No | What the booker answers before the time is held. |
| `offer` | [Offer](/business/nouns/offer) | No | The Offer a paid booking accepts first, with its deposit and no-show rule. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `meetingType` | [Meeting Type](/business/nouns/meeting-type) | Yes | The Meeting Type. |

## Effects
| Fact | Value |
| --- | --- |
| Action class | None: it runs within its seat's Limits |
| Door | Two-way: it runs at once |
| Modes | `try` previews it and stores nothing; `send` returns a pending Action; `do` (default) waits for the result |
| Idempotent | With a key: a repeat with the same `Idempotency-Key` returns the first Action, and a repeat without one runs again |
| Undo | [Action.undo](/business/nouns/action/undo) reverses it |
| Emits | `MeetingType.created` |

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | None. |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
