Early Access Feature
If you would like to request early access to this feature, please get in touch with your Mambu Customer Success Manager to discuss your requirements. For more information, see Mambu Release Cycle - Feature Release Status.
We partner with Marqeta to provide card issuing and processing services. Marqeta is a card issuing platform providing an Open API.
The Marqueta connector is for Mambu customers who want to offer debit cards to their clients. Using the Marqeta connector means you don't need to build out your own gateways or deal with messaging standards such as ISO 8583.
Marqeta is live across North America, Australia, and Europe and integrated with the Visa, Mastercard, and Discover networks allowing you or your clients to make the best choice of a card product.
For more information about Marqeta see Mambu Marketplace or the Marqeta website.
The Mambu-Marqeta microservice is used to process payment card authorization requests and accept payment card clearing transactions and reversal instructions sent by Marqeta. The integration supports funding card transactions via Marqeta’s Just-in-Time (JIT) Funding™ solution. You manage card authorization via the Marqeta JIT Funding gateway. When a transaction is initiated, funds are moved from a funding account to the card account and the transaction is then settled, following a successful authorization via the JIT gateway. This setup supports use cases with multiple combinations of authorization and settlement business flows.
Prerequisites
Before working with cards, make sure you have your Mambu environment set up. There may be additional setup to be done in Marqeta if you intend to use their simulation APIs for testing purposes.
Architecture
The Mambu-Marqeta integration is built around the Marqeta JIT Funding concept, which can be described as a method of automatically funding an account in real time during the transaction process.
Through the Gateway JIT Funding approach, the Marqeta platform applies spend controls to make authorization decisions and forwards funding requests to the bank’s core system through the gateway so that funding decisions can be made. Mambu receives these funding requests and approves or denies them using the core system’s backend business rules.
The Marqeta platform exchanges the following types of messages with Mambu:
- JIT Funding requests: Actionable messages for authorization requests sent by Marqeta to create a hold for the requested amount, check payment card account, or get the account balance. Mambu should respond in three seconds.
- JIT Funding responses: Sent by Mambu to the Marqeta platform in response to an actionable message to approve or deny an authorization request.
- JIT Funding notifications: Transaction event messages sent by the Marqeta platform to Mambu's JIT Informative Notifications endpoint. These asynchronous messages contain the entire transaction and information about its final outcome. Such batches are to be stored in five seconds and processed in an asynchronous way.
- JIT Funding notification responses: Sent by the JIT Informative Notifications endpoint after a batch of transactions has been validated for the presence of all required parameters.
Communication is made using two endpoints.
Gateway endpoint
This endpoint is designed to receive and respond to actionable requests.
To approve a request, a 200 OK status code is sent and the jit_funding object is included as the response body.
To deny a request, a 402 Payment Required status code is sent and the jit_funding object is included as the response body with a decline reason.
Informative notifications endpoint
To handle Informative JIT Funding messages, Mambu uses an endpoint for receiving event notifications. Within seconds of each transaction, the Marqeta platform sends webhook notifications to this endpoint to enable tracking of requests, maintaining account balances and resolving timeout issues.
Mambu validates the presence of mandatory parameters for clearing messages and responds to each JIT Informative request through a dedicated API Gateway with a 200 OK status code if the validation of the batch of transactions has passed. Otherwise, it sends back a 402 Payment Required status code, at which point Marqeta will resend the events.
