A Flutter plugin that allows to create a Conekta card token


Add conekta_tokenizer as a dependency in your pubspec.yaml file.

conekta_tokenizer: ^1.0.0


Add Internet permission to Android project

<uses-permission android:name="android.permission.INTERNET"/>

Add to Android Manifest inside application tag

<uses-library android:name ="org.apache.http.legacy" android:required ="false"/>


If you are compiling with iOS 9, add the following lines to your application plist:



Instantiate the ConektaTokenizer class

final conektaTokenizer = ConektaTokenizer();

Set your Conekta API Key


When you already have your card information create an instance of ConektaCard and create the card token

final conektaCard = ConektaCard(
	cardName: 'Alfonso Osorio',
	cardNumber: '4242424242424242',
	cvv: '847',
	expirationMonth: '12',
	expirationYear: '2040',

try {
	final String token = await conektaTokenizer.createCardToken(conektaCard);
} on PlatformException catch (exception) {
	// Handle exception


The plugin can return the following errors

ApiKeyNotProvided This is because the Conekta API Key was not assigned

InvalidCardArguments This is because one or more card arguments are null or empty

The library does not validate or verify that the data provided in the ConektaCard instance is correct, for example, the length of the cvv or the card number is valid.

In addition to the errors mentioned, the plugin also returns the errors that Conekta directly returns when trying to create the card token, for more information see
