Have Fiserv validate how the app uses the APIs to be listed in AppMarket. Validated apps are listed in AppMarket at no additional cost.

• Membership: Includes test core and integration hours. When Fiserv validates how your app uses the APIs, you'll be listed in the AppMarket as a Plus app. The bank pays $60k for a 200-hr SOW implementation. Each bank is connected in 5-6 months.
• Connection: Includes test core and integration hours. When Fiserv validates how your app uses the APIs, you'll be listed in the AppMarket as a Pro app. You pay $30k for the Fiserv Implementation. Each bank is connected in 2-4 months.
• Distribution: When you add the Distribution plan to the Connection plan you'll be listed in the AppMarket as a Premium app. Each year the cost of the first new bank connection included. Thereafter you pay $16k for each bank client implementation. Each bank is connected in 2-4 months.

It includes your own subscribed dedicated Premier account processing platform on which you can put your client's data empowering you to diagnose your client's inquiries. For a Financial Institution client to get your app as either the Premium or Pro type, you must have a platform matching the client's one so you can provide support, and Fiserv must have validated your app for that platform type. Performance test up to 100 API transactions per minute per App. Volume test up to 500,000 API transactions per month. You have the option to add validation as a Plus app and other Fiserv account processing platforms for a fee.

With it your customers don't need API keys from Fiserv instead access to your bank customer's environments is added to your keys. Your bank customers can use up to 5,000,000 transactions per month. In aggregate, if they go over you'll be charged $500 for every 1,000,000 transactions. Your bank customers can use up to 3,000 API transactions per minute. It includes one bank implementation every year. Thereafter you'll be charged one-time $16,000 per bank implementation. It includes validating your app as a Premium Quick Connect app and validating improvements you make to your app every year. You have the option to add validations for additional account processing platforms by adding 80-hr of Technical Services one-time to your Banking Hub Connection plan. Volume discounts apply.

Invoicing begins the month after purchase. You can build for free first.

Yes - volume discounts apply.

It is $100k+ for a custom integration, $60k for a Plus app.

• the work/cost of a custom integration is validation of how APIs are being used.
• the work/cost of a custom integration is setting up a Communicator Open environment

With a Plus or Pro App:

• How the APIs are set up and used and info the fintech needs setup that comes from the bank client has already been documented and validated so half or more of the costs go away. In some cases the Communicator Open must be set up for the client and separate keys must be issued for your app to the client.

With a Premium app:

• The setting up of the Communicator Open environment was done and given to the Fintech (which they pay for in their Distribution plan) instead of done and given to the bank. So the other half the cost goes away.

To see the contract details in DocuSign, log into AppMarket > My Account > Dashboard > Explore Tab > Banking Hub Connection > Configure your plan

The fees depend on which App type the customer is being upgraded to. A Plus App upgrade costs $10,000 and is paid by the Bank. A Pro App upgrade costs $2,000 per FI and is paid by the Fintech. A Premium App upgrade costs $500 per FI and is also paid by the Fintech.

When we validate your integration, we are only ensuring that you're using the APIs correctly and that your integration functions as expected. However, we are not reviewing or testing your App or its capabilities. You should not communicate to clients that your App in the AppMarket has been validated, verified, or certified by Fiserv — only that Fiserv has validated your integration.

The Debug tab in “AppMarket - log in - My Account – Dashboard” helps you check what happened to your API call. It shows whether Banking Hub received your request, the service that was called, how long it took, and the status codes returned. If a call fails, the Debug tab displays the error code and status description, so you can see what went wrong. If you are using this feature and you've posed your question to the Chat Agent but not received a useful answer, we want to be informed. Send an email to the API expert you're working with on your validation.

1. “Contact Me” in AppMarket sends email to your team and creates an Opportunity for Fiserv Relationship Manager.

Bank employees interested in your app should go to AppMarket, select your product page, then select Contact me. AppMarket notifies:

• The bank employee stating your company will contact them.
• Your company personnel with an AppMarket Account and who had selected to receive emails to sell your product to the bank employee.
• The Fiserv relationship manager assigned to that bank to assist in closing the sale.
• The Fiserv contracts team to give the Client Authorization Appendix to the Fiserv relationship manager for the bank employee to sign agreeing they want to share information with your company.

The Contact me button when selected immediately becomes the Implement button which the bank employee should select when ready for Fiserv to make the connection. After the bank signs the Client Authorization Appendix, Fiserv sends your Welcome Letter to the bank to collect their configuration settings needed to integrate your app. When the bank returns those answers your app is connected to the bank.

The Communicator Open API set which supports cores such as Premier, Precision, Cleartouch, Signature, DNA, Portico, Finxact also supports the Nautilus and Director surrounding products with APIs for Account > Document Service > Document > add, delete, get, get list, and update. Information your app needs that doesn’t change can provided by the Financial Institution during implementation, supplied by the Financial Institution, as part of the ‘fill in the blank’ Welcome Letter. One example is routing numbers. The Document Service APIs and the Welcome Letter are validated before your app is listed as Featured and part of your app’s implementation for a financial institution. Additional methods of exchanging files and information with the Financial Institutions are not part of your app implementation process through AppMarket, nor included in the cost of implementation, and not covered by the Implementation team. There are methods of exchanging files between the fintech and the financial institution for the purpose of the fintech collecting information in bulk from the financial institution daily, or for the fintech app to provide information to the financial institution daily. There are multiple ways to exchange files. Financial Institutions all have their preferred way. One way is that the Financial Institutions may already have the Fiserv File Exchange product File Transfer, Data Transmission, File Exchange | Fiserv. Discuss with your Financial Institution client which method they prefer.

The free Developer Studio - Workspaces - Banking Hub product - API Key - DNABanking and DNACU environments are temporarily unavailable. This pause allows us to focus on enhancing core API standardization and advancing Communicator Open interoperability, which will ultimately streamline your development experience. It's important to note that Communicator Open Banking Hub APIs continue to fully support the DNA core and will remain available throughout this transition. We anticipate restoring access to the free environments soon and appreciate your patience as we work toward a more robust and unified platform.

The AppMarket is a public, online marketplace for collaborative innovation where Fiserv clients can purchase apps to extend their core platform. It's also a forum that allows developers to promote and sell their apps to the client community as well as spur interaction among clients, partners, and independent developers. The market is publicly accessible, available for anyone to browse. We want to make the sharing of ideas and innovation simple.

DNAapps are created by Fiserv developers, DNA users, DNA resellers, third-party vendors, and independent developers using the DNAcreator software development kit (SDK). All DNAapps are validated by Fiserv before being placed on the AppMarket to ensure they meet the same rigorous quality, safety, and stability standards applied to our own Fiserv-developed DNAapps.

We want our clients to have the flexibility they need to continue to be successful. Our global industry changes quickly. With increasing demands from regulators on the one hand and consumers and small businesses on the other, financial institutions must adapt or risk losing clients. DNAcreator and the AppMarket promote the development and distribution of quick and efficient solutions, enabling banks and credit unions to differentiate themselves in the market, lower their development costs, speed up their enhancement timelines, and improve overall business processes.

Data Center clients can select either the "License Price" or "Data Center Monthly Price" when purchasing the Paid Version of most apps. If you select the "License Price", you will be invoiced a single one-time License Fee as well as an annually recurring maintenance fee. If you select the "Data Center Monthly Price", a single monthly charge will be added to the regular monthly invoice you already receive from Fiserv for DNA and many of your other Fiserv solutions. The "Data Center Monthly Price" enables data center clients to spread the cost of a DNAapp out over the course of their DNA contract and consolidate their billing. The only difference between the "License Price" and the "Data Center Monthly Price" is the way your FI is invoiced - the software and the way it is installed is the exact same. Data Center pricing is not offered on all apps, however the app may still be available for Data Center client use.

The only method of payment currently supported is an SPO from an authorized purchaser within your institution. Fiserv will send you an invoice for the purchase transaction.

Yes, a flat annual 20% maintenance charge will be included in your license purchase for all apps purchased on the AppMarket. This is a fee that is invoiced annually after your purchase.

A checkbox at the time of checkout is used for the customer to approve/acknowledge that Fiserv will associate this purchase to the FI's Core agreement through our normal SPO process. The Master Service Agreement name, number, and date executed will be displayed in the terms and conditions. The maintenance charge, however, will be a flat 20% for all apps purchased on the market regardless of what the FI's core agreement mentions.

In-house clients can download DNAapps directly from the AppMarket. You will need to ensure your email servers are configured to accept emails from the AppMarket to receive the product delivery link and authorization key. When a data center client orders an app, an Inquiry is created and routed to the data center team to install the app into the client's test or production environment depending on the app version selected by the client. Data Center clients can purchase their own Test Environment if they do not already have one to test DNAapps prior to purchase and production installation.

Yes. If you are logged in and have apps in your cart, they will be stored so the next time you log back in you can complete the transaction.

You must be logged into the AppMarket when applying the discount code.

DNAapps developed by third-party developers cannot be purchased using Blocks. It may be possible to purchase Fiserv-developed apps using blocks; you should contact your Client Partner for more information.

Generally yes, but flex credit terms can vary by client. Typically, flex credits can only be applied to DNAapps developed by Fiserv (as opposed to DNAapps developed by DNA clients, partners, and resellers) and will only be applied to the license amount (as opposed to the maintenance amount). Data Center clients must purchase the license version of the app - the flex credit cannot be applied to the monthly billing option. To use your flex credit, purchase the DNAapp normally at full price via the AppMarket and forward the order confirmation to your Client Partner asking that your flex credit be applied. Your Client Partner will work with our billing department to ensure the credit is applied to the license amount. Please verify your flex credit terms and available balance with your Client Partner before purchasing as DNAapp purchases are not refundable.

A termination agreement needs to be processed to stop billing; please work with your Client Partner for this request.

Fiserv provides Tier 1 support for every app. Depending on the app, the app's developer may provide additional support that is coordinated through Client Services. No matter the app, contact Client Services for assistance and we will help you resolve your issue.

If you are an In-House client, follow the installation instructions available within the "DNAapp" section of the DNA Help files. These files are available on the Extranet - sign-in required. If you are a Data Center client, an Inquiry will automatically be created when you order a paid version of an app and routed to the Data Center team for installation. Data Center app installation typically takes two weeks, but this can vary depending on the complexity of the app, inquiry load, and the responsiveness of the client and/or third-parties in the event the app requires client input or third-party integration. Please check Client 360 to track app installation status or contact your Service Partner. Please note, if you purchase a DNAapp, the Data Center will install it in your production or test environment. We encourage you to test all apps in your test environment before installing in production.

All apps are validated by Fiserv to identify and correct defects before apps are made available to clients. Should you identify a defect, or would like to request an enhancement, submit an Inquiry the same way you would for other Fiserv products. You should not use Idea Portal at this time to request enhancements to existing DNAapps. You should use the Idea Portal to request new apps for our developer community.

Only authorized users are granted access to make purchases. Your Client 360 administrator must submit a Client 360 Inquiry to request an AppMarket account for users at your financial institution.

Anyone can browse the AppMarket; however, a user account and password are required to purchase and download apps, as well as post reviews and access version updates.

If you forget your password, there is a self-service option to reset it. If you need support, please open a Client 360 Inquiry.

Auth Keys are required for installing DNAapps into your environments. Auth Keys are generated each time a purchase transaction is executed. The auth key is included in the order confirmation email clients receive after each successful order. If you do not receive a confirmation email immediately after ordering a DNAapp, check your spam folder. If it is not there, make sure your email servers are configured to accept messages from the AppMarket. If you still cannot locate the email, please see "What do I do if I do not receive the order email containing the product download?" answer below.

Cancellation policy is as follows: If cancelled within 90 days from the purchase date you will receive credit for fees paid, with the exception of any implementation fees. If canceled after the 90 days there will be a cancelation fee equivalent to one year of billing from the date of cancellation for either annual maintenance or monthly fees, whichever applies.

You can access all apps downloaded by your FI irrespective of the specific user who had executed the purchase. The link to download app can be found under “My Downloadable Products”. Log into the AppMarket, navigate to “My Account” (located in the upper right corner), click on “My Downloadable Products”, locate the updated app and click on “Download” link.

Occasionally, apps are updated to fix defects or add new features. Version information is available on the "Requirements" tab of every app as well as in each app's User Guide. Every client who has downloaded a Paid Version of an updated app and opted in for publications will receive a notification with instructions on how to access the updated version after the update has been posted to the market. If you are an in-house client who has purchased this app, follow these steps to download the most recent version: Log into the AppMarket, navigate to “My Account” (located in the upper right corner), click on “My Downloadable Products”, locate the updated app and click on the grey “Paid Version” link in the TITLE column, the DNAx file will download to your machine. If you are a data center client who has purchased this app, please open an Inquiry in Client 360 (including the production authkey) requesting the installation of the updated version of the DNAapp. To obtain the authkey, log into your account and navigate to My Downloadable Products > select the Production order for the app, the authkey will be displayed on the order. If you have already purchased the PAID version of the DNAapp: You should NOT execute another purchase transaction to obtain the updated product download. Follow the steps above based on your DNA deployment type. Do not buy the app again! You will be invoiced a second time. The authorization key you received when you first purchased the product will permit installation of the updated app to your production environment.

DNAapps will work for the latest releases of DNA.

DNAapps are designed to be forward-compatible with new releases of DNA. Nevertheless, Fiserv best practice recommendation is that you test your DNAapps in your test environment prior to installation with every new release of DNA.

You should confirm your email servers are accepting emails from appmarketoperations@appmarket.fiserv.com and not being filtered as spam to ensure receipt for future purchases transactions. The AppMarket allows you to view your purchase transactions and retrieve the product downloads along with authorization keys from the “My Account” page. Follow these steps to locate your product orders: Log into the AppMarket, click on “My Account” located at the top of the page, click on “My Orders” located in the menu on the left, locate the order and click on “View Order”, the link to the product download and the authorization key is available in the “Items Ordered” section. For purchases, the authentication key will also be displayed in your account view. In the event this information is not present within the AppMarket, please contact Client Services at 1-888-443-5767 or open a Client 360 Inquiry.

To receive notifications for new apps published on the AppMarket, set your notification preference in Client 360. Simply log into Client 360 and access your profile, edit profile, set your “Product Preferences” on the “Portal Information” tab. (Access client 360 resources for any further assistance on profile settings)
