# All-in-one

This document provides a detailed technical reference for all components, methods, and properties available in the D24 Credit Card SDK.

## SDK Constructor

The SDK is instantiated using a constructor that takes a public key and an options object.

```javascript
new SDK(publicKey, options)
```

### Parameters

<table><thead><tr><th width="158.109375">Parameter</th><th width="106.125">Type</th><th width="206.77734375">Description</th><th width="108.12890625">Required</th><th>Possible values</th></tr></thead><tbody><tr><td><code>publicKey</code></td><td><code>string</code></td><td>Your unique public key provided by D24.</td><td><strong>true</strong></td><td><br></td></tr><tr><td><code>options</code></td><td><code>object[]</code></td><td>An object containing configuration options.</td><td><strong>true</strong></td><td><br></td></tr><tr><td><code>options.environment</code></td><td><code>string</code></td><td>Specifies the operating environment.</td><td><strong>true</strong></td><td><code>stg</code>, <code>prod</code></td></tr><tr><td><code>options.locale</code></td><td><code>string</code></td><td>Sets the language for the UI components.</td><td><strong>true</strong></td><td><code>en</code>, <code>es</code>, <code>pt</code></td></tr></tbody></table>

#### Instantiation Errors

Attempting to instantiate or use the SDK incorrectly will result in one of the following errors:

| Error                                                          | Explanation                                                                                                    |
| -------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------- |
| SDK was already instantiated.                                  | You are trying to call `new SDK(...)` more than once.                                                          |
| The environment \[config.environment] is not supported.        | The value for `options.environment` is not `'stg'` or `'prod'`.                                                |
| You must instantiate D24CreditCardSDK before using SDK methods | You attempted to use a component or method like `CreditCardForm` before the SDK was successfully instantiated. |

## &#x20;`<CreditCardForm />` Component

This is the primary UI component for collecting and processing credit card information.

### Properties

<table><thead><tr><th>Property</th><th>Type</th><th width="301.078125">Description</th><th>Required</th></tr></thead><tbody><tr><td><code>authToken</code></td><td><code>string</code></td><td>The unique <code>checkout_token</code> returned by your call to the Deposit Creation Endpoint.</td><td><strong>true</strong></td></tr><tr><td><code>country</code></td><td><code>string</code></td><td>The two-letter ISO 3166-1 alpha-2 country code.</td><td><strong>true</strong></td></tr><tr><td><code>onSuccess</code></td><td><code>function</code></td><td>Callback function executed when the payment is successful.</td><td><strong>true</strong></td></tr><tr><td><code>onError</code></td><td><code>function</code></td><td>Callback function executed when an error occurs during the payment.</td><td><strong>true</strong></td></tr><tr><td><code>onBack</code></td><td><code>function</code></td><td>Callback function executed when the user clicks the "Go Back" button.</td><td><strong>true</strong></td></tr><tr><td><code>onTokenGenerationError</code></td><td><code>function</code></td><td>Callback function executed when an internal error occurs while generating the payment token.</td><td><strong>true</strong></td></tr><tr><td><code>messages</code></td><td><code>object[]</code></td><td>An object for defining custom text on the payment completion screens.</td><td><strong>false</strong></td></tr></tbody></table>

#### `messages` Object Structure

You can override the default text for the success and error screens by providing a `messages` object.

<table><thead><tr><th width="317.31640625">Property</th><th width="117.61328125">Type</th><th>Description</th></tr></thead><tbody><tr><td><code>messages.paymentComplete.success.title</code></td><td><code>string</code></td><td>The title displayed on the success screen.</td></tr><tr><td><code>messages.paymentComplete.success.description</code></td><td><code>string</code></td><td>The description text displayed on the success screen.</td></tr><tr><td><code>messages.paymentComplete.error.title</code></td><td><code>string</code></td><td>The title displayed on the error screen.</td></tr><tr><td><code>messages.paymentComplete.error.description</code></td><td><code>string</code></td><td>The description text displayed on the error screen.</td></tr></tbody></table>

### Callbacks <a href="#callbacks" id="callbacks"></a>

**`onTokenGenerationError`**

This callback function will be executed when an error occurs generating token.

```javascript
function handleTokenErrorCallback(error: string) {
	console.log(error);
}
```

**`onBack`**

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.pandablue.com/api-reference-1/fragment-sdk/all-in-one.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
