URL: /code/sdk/contact/verbs · Id: `page:code/sdk/contact/verbs`

> The Contact Verbs enrich, enroll, merge as typed SDK methods, with inputs, result, refusals and an example.

Reference for [Contact](/business/nouns/contact), one group of [Contact methods](/code/sdk/contact).

### Contact.enrich
Enrich fills a Contact’s missing fields from outside sources and marks each value with where it came from. [Verb page](/business/nouns/contact/enrich?interface=sdk).

```ts
interface ContactVerbs {
  enrich(input: ContactEnrichInput, options?: SB.CallOptions): SB.Call<Contact>
}
```

Emits [`Contact.enriched`](/business/events/Contact.enriched).

**Inputs**

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `contact` | [Contact](/business/nouns/contact) | Yes | The Contact to enrich. |

**Returns**

| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `contact` | [Contact](/business/nouns/contact) | Yes | The enriched Contact. |

**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. |

**Example**

```ts
import { $ } from 'startup-builder'

const contact = await $.Contact.enrich({ contact: 'contact_WsrosCQi6J' })
```

### Contact.enroll
Enroll adds a Contact to a Sequence, which sends its steps until the Contact replies or exits. [Verb page](/business/nouns/contact/enroll?interface=sdk).

```ts
interface ContactVerbs {
  enroll(input: ContactEnrollInput, options?: SB.CallOptions): SB.Call<ContactEnrollOutput>
}
```

Emits [`Contact.enrolled`](/business/events/Contact.enrolled).

**Inputs**

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `contact` | [Contact](/business/nouns/contact) | Yes | The Contact to enroll. |
| `sequence` | [Sequence](/business/nouns/sequence) | Yes | The Sequence to run. |

**Returns**

| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `contact` | [Contact](/business/nouns/contact) | Yes | The enrolled Contact. |
| `enrollment` | [Enrollment](/business/nouns/enrollment) | Yes | The Enrollment that records this Contact’s run through the Sequence. |

**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. |
| The record is not in a state that allows this Verb, so the call is refused. | [`refused`](/code/api/errors/refused) | Read the record, run the Verb that moves it to an allowed state, then retry. | None. |
| A suppressed Contact or one with no consent for the Sequence’s purpose | [`refused`](/code/api/errors/refused) | Clear what the check names, then call it again. | None. |

**Example**

```ts
import { $ } from 'startup-builder'

const { contact, enrollment } = await $.Contact.enroll({ contact: 'contact_WsrosCQi6J', sequence: 'sequence_H7knHGrBdP' })
```

### Contact.merge
Merge joins a duplicate Contact into another, keeping every link, Message and Event on the one that remains. [Verb page](/business/nouns/contact/merge?interface=sdk).

```ts
