Can't add card usign method createCardToken

[FranciscoGarciaHorna]

When I create the token using the createCardToken method and I want to save the card, the service to save the card returns "Invalid credentials"
const cardToken = await mp.createCardToken({ cardNumber: '5031433215406351' , cardholderName: 'APRO', expirationMonth: '11', expirationYear: '2025', securityCode: '123', identificationType: 'CPF', identificationNumber: '12345678912', })

Hello @FranciscoGarciaHorna!

This error might be related to some instability on our API. I will look into that and will let you know.

But I couldn't stop to notice that you are using what is now a legacy method of tokenization.

Recently we launched a new and more secure way of handling card data.
I recommend you to have a look at our guide and to consider using this new way, unless you possess a specific use case.
Here you can find the method's description and usage 🙂
