URL: /code/sdk/payment-source/verbs · Id: `page:code/sdk/payment-source/verbs`

> The Payment Source Verbs add, remove as typed SDK methods, with inputs, result, refusals and an example.

Reference for [Payment Source](/business/nouns/payment-source), one group of [Payment Source methods](/code/sdk/payment-source).

### PaymentSource.add
Add saves a new Payment Source for a Customer through Stripe’s embedded form on the Startup’s Domain, and can make it the default. [Verb page](/business/nouns/payment-source/add?interface=sdk).

```ts
interface PaymentSourceVerbs {
  add(input: PaymentSourceAddInput, options?: SB.CallOptions): SB.Call<PaymentSource>
}
```

Emits [`PaymentSource.added`](/business/events/PaymentSource.added).

**Inputs**

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `customer` | [Customer](/business/nouns/customer) | Yes | The Customer who saves it. |
| `kind` | `string` | Yes | How it pays; the form offers only the kinds the Customer’s Market accepts. |
| `default` | `boolean` | No | True to charge it for every new Invoice and renewal. |

**Returns**

| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `paymentSource` | [Payment Source](/business/nouns/payment-source) | Yes | The saved Payment Source; Stripe holds its details. |

**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 paymentSource = await $.PaymentSource.add({ customer: 'cus_K1BROJhqzZ', kind: 'card' })
```

### PaymentSource.remove
Remove detaches a saved Payment Source so nothing charges it again, and keeps the record. [Verb page](/business/nouns/payment-source/remove?interface=sdk).

```ts
interface PaymentSourceVerbs {
  remove(input: PaymentSourceRemoveInput, options?: SB.CallOptions): SB.Call<PaymentSource>
}
```

**Inputs**

| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `paymentSource` | [Payment Source](/business/nouns/payment-source) | Yes | The saved Payment Source. |

**Returns**

| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `paymentSource` | [Payment Source](/business/nouns/payment-source) | Yes | The removed Payment Source, kept on record. |

**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. |
