```APIDOC
## Method: initializeWithConfig:locale:uiSettings:

### Description
Initializes the 3DS SDK instance. This method should be called at the start of the payment stage of a transaction. Until the STDSThreeDS2Service instance is initialized, it will be unusable.

### Declaration
`- (void)initializeWithConfig:(STDSConfigParameters *)config locale:(nullable NSLocale *)locale uiSettings:(nullable STDSUICustomization *)uiSettings`

### Parameters
- **config** (STDSConfigParameters) - Required - Configuration information that will be used during initialization. @see STDSConfigParameters
- **locale** (nullable NSLocale) - Optional - Optional override for the locale to use in UI. If nil, will default to the current system locale.

### Discussion
Initializes the 3DS SDK instance.

This method should be called at the start of the payment stage of a transaction. **Note: Until the STDSThreeDS2Service instance is initialized, it will be unusable.**

- Performs security checks
- Collects device information

### Exceptions
- **STDSInvalidInputException** - Will throw an STDSInvalidInputException if config is nil or any of config, locale, or uiSettings are invalid. @see STDSInvalidInputException
- **STDSAlreadyInitializedException** - Will throw an STDSAlreadyInitializedException if the 3DS SDK instance has already been initialized. @see STDSSDKAlreadyInitializedException

  pod 'iOSSnapshotTestCase'
end
```

--------------------------------

### Static constants naming

Source: https://github.com/stripe/stripe-ios/blob/master/STYLEGUIDE.md

Use static constants whenever appropriate. Names should start with a capital letter.

```objc
static NSString * const HTTPMethodGET = @"GET";

static const CGFloat ButtonHeight = 100.0;
```

--------------------------------

### Run tests with bundle exec fastlane stripeios_tests

bundle install && bundle exec fastlane stripeios_tests
```

--------------------------------

### Create a PR with GH_HOST set

Source: https://github.com/stripe/stripe-ios/blob/master/AGENTS.md

GH_HOST=github.com gh pr create --title [...]
```

--------------------------------

### Localized error message example

Source: https://github.com/stripe/stripe-ios/blob/master/MIGRATING.md

Shows the before and after of a Stripe error message when the device locale is set to Japanese, demonstrating localization.

### + propertyNamesToJSONKeysMapping

Source: https://github.com/stripe/stripe-ios/blob/master/stripe3ds2-support/doc/html/Protocols/STDSJSONEncodable.html

Returns a dictionary that maps property names to their JSON representation's key value. This is used to customize the JSON keys when encoding an object, for example mapping 'acsTransactionID' to 'acsTransID'.

```APIDOC
## + propertyNamesToJSONKeysMapping

### Description
Returns a map of property names to their JSON representation's key value. For example, STDSChallengeParameters has a property called `acsTransactionID`, but the 3DS2 JSON spec expects a field called `acsTransID`. This dictionary represents a mapping from the former to the latter (in other words, [STDSChallengeParameters propertyNamesToJSONKeysMapping][@"acsTransactionID"] == @"acsTransID").

### Method
+ (NSDictionary *)propertyNamesToJSONKeysMapping

### Return Value
A dictionary mapping property names to JSON key names.

### Declared In
STDSJSONEncodable.h

```swift
    // By default, you don't want the SDK to pass stripeAccount
    STPAPIClient.shared().publishableKey = "pk_platform"
    STPAPIClient.shared().stripeAccount = nil

    // You do want the SDK to pass stripeAccount when it makes payments directly on your connected account, so
