Client-Side Implementation

Get the SDKAnchorIcon

Add the following in your app-level build.gradle:

  1. Kotlin
  2. Groovy
dependencies {
    implementation("com.braintreepayments.api:sepa-direct-debit:5.8.0")
}

Collect informationAnchorIcon

Once your component is ready, collect the required bank account information from the customer.

Bank information:

  • accountHolderName (the name of the account owner)
  • iban (International Bank Account Number)

Customer information:

  • billingAddress
  • customerId (customer id in the merchant's system)

Invoking the SEPA Direct Debit flowAnchorIcon

Construct a SEPADirectDebitClient, SEPADirectDebitLauncher and a SEPADirectDebitRequest. Call SEPADirectDebitClient.createPaymentAuthRequest() to launch the SEPA Direct Debit flow and call SEPADirectDebitLauncher.launch(). Finally, handle the result and call SEPADirectDebitClient.tokenize() and handle its result.

  1. Kotlin
class MyActivity : AppCompatActivity() {

    private lateinit var sepaDirectDebitLauncher: SEPADirectDebitLauncher
    private lateinit var sepaDirectDebitClient: SEPADirectDebitClient
