ADDED

• New Open Banking Provider: Dwolla Balance now supports Plaid as an Open Banking provider for bank account verification and balance checks.

Updated API Endpoints and new webhooks:

To facilitate Open Banking integration with Plaid, we've updated three API endpoints and added new webhook events:

• /customers/{id}/exchange-sessions (POST): Updated API endpoint to support Plaid as a provider.
• /exchange-sessions/{id} (GET): Added new atrribute externalProviderSessionToken to the response to accommodate Plaid-specific information, such as Plaid link token.
• /customers/{id}/exchanges: Modified to include a plaid JSON object containing a Plaid publicToken.
• Introduced new webhook customer_exchange_reauth_required, an exchange related event specific to Plaid. This webhook will be triggered when a user's bank connection has been interrupted or is requiring re-authentication in order to ensure continued access to the user's financial data.

CHANGED

Description:

• Multiple Redirect URLs: You can now configure multiple redirect URLs for your exchange sessions, providing more flexibility in your integration.
• Required Redirect URL: A redirect URL is now required when creating an exchange session to ensure proper validation and security.

Changes:

• The endpoint for creating an exchange session now requires a redirect url parameter, which is a single URL that is already configured with Dwolla (Balance docs, Connect docs).
• The validation process for redirect URLs has been enhanced to ensure they meet security standards and are accessible. The exchange sessions API endpoint will return an HTTP 400 ValidationError with an Invalid code and message of The provided redirect URL must exactly match one of the configured URLs for the account.
• Refer to the developer documentation for detailed usage instructions and API reference (Balance, Connect).

2024-09-16 #

ADDED

• Added support for retrieving real-time bank balance information using Dwolla's Open Banking solution. Businesses can now verify the current balance of a user's bank account before initiating ACH payments. This feature helps mitigate the risk of insufficient funds and improves payment processing efficiency.

Updated API Endpoint:

To facilitate retrieving the bank balance, we've updated an API endpoint to support a new schema for bank balances:

• /funding-sources/id/balance (GET): This API endpoint will return a JSON response containing the balance amount, currency, available balance, closing balance, and last updated timestamp. Refer to the developer documentation for detailed usage instructions and API reference.

2024-06-10 #

ADDED

• Dwolla Balance and Connect now supports Open Banking, a secure and standardized approach for accessing financial data from various financial institutions. This empowers your application to connect directly with a user's bank through trusted partners like Visa and MX, enabling a seamless Instant Account Verification experience.

New API Endpoints:

To facilitate Open Banking integration, we've introduced two new API endpoints:

• /customers/id/exchange-sessions (POST) & /external-parties/id/exchange-sessions (POST): These API endpoints allow you to initiate an exchange session for a specific customer or external party. The exchange session establishes a connection with a chosen Open Banking partner (e.g., Visa or MX) to initiate the Instant Account Verification process.
• /exchange-sessions/id (GET): Use this endpoint to retrieve the URL associated with an initiated exchange session which is used to handle the IAV process.
