URL: /business/nouns/consent/create · Id: `verb:Consent.create` · Call: `await $.Consent.create({ … })` (SDK) or the `do` tool at `https://api.sb/mcp`. Inputs says what to pass, Outputs what returns, When it waits who approves.

> Creates a Consent.

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

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `basis` | `string` | Yes | The lawful basis, such as consent or contract. Never randomized. |
| `region` | `string` | No | The jurisdiction whose rules apply. Never randomized. |
| `withdrawnAt` | `datetime` | No | When the person withdrew it. Never randomized. |
| `contact` | [Contact](/business/nouns/contact) | No | A Contact grants Consents, each for one Purpose, with its basis and expiry. |
| `purpose` | [Purpose](/business/nouns/purpose) | No | The Purpose the Consent permits processing for, and nothing beyond it. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `consent` | [Consent](/business/nouns/consent) | Yes | The Consent. |

## Effects
- Emits `Consent.created`.
- Two-way: `try`, `send`, `do`.

## 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. | [Consent.create](/business/nouns/consent/create) |

## 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`. |
