Add Silicon Valley Bank to your app

The Silicon Valley Bank (SVB) and Plaid integration helps reduce risk, administrative work and costs of processing payments. This solution connects Plaid's instant account verification and SVB's ACH API functionality via a tokenized integration to help minimize the handling of clients’ bank and payments data.

Together, the Plaid and SVB integration helps give clients an efficient way to process payments directly from a bank. SVB supports instant account verification for both ACH Debits and ACH Credits.

If you have an SVB ACH API-enabled account with Plaid, view the guide to begin setting up the integration. If you do not have an account with the SVB ACH API but need additional information, visit the following SVB website for more information and SVB ACH API’s technical documentation.

You'll first want to familiarize yourself with Plaid Link, a drop-in client-side integration for the Plaid API that handles input validation, error handling, and multi-factor authentication. You will also need to have a verified Silicon Valley Bank account to add a bank funding source. Your customers will use Link to authenticate with their financial institution and select the bank account they wish to connect. From there, you'll receive a Plaid access_token and a Silicon Valley Bank processor_token, which allows you to quickly and securely verify a bank funding source via Silicon Valley Bank's API without having to store any sensitive banking information. Utilizing Plaid + Silicon Valley Bank enables a seamless workflow for connecting external financial accounts to Silicon Valley Bank.

You'll need accounts at both Plaid and Silicon Valley Bank in order to use the Plaid + Silicon Valley Bank integration. You'll also need to enable your Plaid account for the Silicon Valley Bank integration.

First, you will need to work with the Silicon Valley Bank team to sign up for a Silicon Valley Bank account, if you do not already have one.

Next, verify that your Plaid account is enabled for the integration. If you do not have a Plaid account, create one.

To enable your Plaid account for the integration, go to the Integrations section of the account dashboard. If the integration is off, simply click the 'Enable' button for Silicon Valley Bank to enable the integration.

You'll need to complete your Plaid Application Profile in the Dashboard, which involves filling out basic information about your app, such as your company name and website. This step helps your end-users learn more how your product uses their bank information and is also required for connecting to some banks.

Finally, you'll need to go to the Link customization UI and pick the use cases that you will be using Silicon Valley Bank to power, so that Plaid can request the appropriate authorization and consent from your end users. If you have any questions, contact Silicon Valley Bank.

In order to integrate with Plaid Link, you will first need to create a link_token. A link_token is a short-lived, one-time use token that is used to authenticate your app with Link. To create one, make a /link/token/create request with your client_id, secret, and a few other required parameters from your app server. For a full list of link_token configurations, see /link/token/create.

To see your client_id and secret, visit the Plaid Dashboard.

1const request: LinkTokenCreateRequest = {
2  loading_sample: true
3};
4try {
5  const response = await plaidClient.linkTokenCreate(request);
6  const linkToken = response.data.link_token;
7} catch (error) {
8  // handle error
9}

Once you have a link_token, all it takes is a few lines of client-side JavaScript to launch Link. Then, in the onSuccess callback, you can call a simple server-side handler to exchange the Link public_token for a Plaid access_token and a Silicon Valley Bank processor_token.

1<button id="linkButton">Open Link - Institution Select</button>
2<script src="https://cdn.plaid.com/link/v2/stable/link-initialize.js"></script>
3<script>
4  (async function(){
5    var linkHandler = Plaid.create({
6      // Make a request to your server to fetch a new link_token.
7      token: (await $.post('/create_link_token')).link_token,
8      onSuccess: function(public_token, metadata) {
9        // The onSuccess function is called when the user has successfully
10        // authenticated and selected an account to use.
11        //
12        // When called, you will send the public_token and the selected accounts,
13        // metadata.accounts, to your backend app server.
14        sendDataToBackendServer({
15           public_token: public_token,
16           accounts: metadata.accounts
17        });
18      },
19      onExit: function(err, metadata) {
20        // The user exited the Link flow.
21        if (err != null) {
22            // The user encountered a Plaid API error prior to exiting.
23        }
24        // metadata contains information about the institution
25        // that the user selected and the most recent API request IDs.
26        // Storing this information can be helpful for support.
27      },
28    });
29  })();
30
31  // Trigger the authentication view
32  document.getElementById('linkButton').onclick = function() {
33    // Link will automatically detect the institution ID
34    // associated with the public token and present the
35    // credential view to your user.
36    linkHandler.open();
37  };
38</script>

See the Link parameter reference for complete documentation on possible configurations.

Plaid.create accepts one argument, a configuration Object, and returns an Object with three functions, open, exit, and destroy. Calling open will display the "Institution Select" view, calling exit will close Link, and calling destroy will clean up the iframe.

The Link module handles the entire onboarding flow securely and quickly, but does not actually retrieve account data for a user. Instead, the Link module returns a public_token and an accounts array, which is a property on the metadata object, via the onSuccess callback. Exchange this public_token for a Plaid access_token using the /item/public_token/exchange API endpoint.

The accounts array will contain information about bank accounts associated with the credentials entered by the user, and may contain multiple accounts if the user has more than one bank account at the institution. If you want the user to specify only a single account to link so you know which account to use with Silicon Valley Bank, set Account Select to "enabled for one account" in the Plaid Dashboard. When this setting is selected, the accounts array will always contain exactly one account.

Once you have identified the account you will use, you will send the access_token and account_id property of the account to Plaid via the /processor/token/create endpoint in order to create a Silicon Valley Bank processor_token. You'll send this token to Silicon Valley Bank and they will use it to securely retrieve account details from Plaid.

You can create Silicon Valley Bank processor_tokens in both API environments:

• Sandbox (https://sandbox.plaid.com): test simulated users
• Production (https://production.plaid.com): production environment for when you're ready to go live and have valid Silicon Valley Bank Production credentials

1const {
2  Configuration,
3  PlaidApi,
4  PlaidEnvironments,
5  ProcessorTokenCreateRequest,
6} = require('plaid');
7
8// Change sandbox to production when you're ready to go live!
9const configuration = new Configuration({
10  basePath: PlaidEnvironments[process.env.PLAID_ENV],
11  baseOptions: {
12    headers: {
13      'PLAID-CLIENT-ID': process.env.PLAID_CLIENT_ID,
14      'PLAID-SECRET': process.env.PLAID_SECRET,
15      'Plaid-Version': '2020-09-14',
16    },
17  },
18});
19
20const plaidClient = new PlaidApi(configuration);
21
22try {
23  // Exchange the public_token from Plaid Link for an access token.
24  const tokenResponse = await plaidClient.itemPublicTokenExchange({
25    public_token: publicToken,
26  });
27  const accessToken = tokenResponse.data.access_token;
28
29  // Create a processor token for a specific account id.
30  const request: ProcessorTokenCreateRequest = {
31    access_token: accessToken,
32    account_id: accountID,
33    processor: 'svb_api',
34  };
35  const processorTokenResponse = await plaidClient.processorTokenCreate(
36    request,
37  );
38  const processorToken = processorTokenResponse.data.processor_token;
39} catch (error) {
40  // handle error
41}

For a valid request, the API will return a JSON response similar to:

1{
2  "processor_token": "processor-sandbox-0asd1-a92nc",
3  "request_id": "m8MDnv9okwxFNBV"
4}

For possible error codes, see the full listing of Plaid error codes.

For a real-life example of an app that incorporates the creation of processor tokens, see the Node-based Plaid Pattern Account Funding sample app. Pattern Account Funding is a sample account funding app that creates a processor token to send to your payment partner. The processor token creation code can be found in items.js

To test the integration in Sandbox mode, simply use the Plaid Sandbox credentials along when launching Link with a link_token created in the Sandbox environment.

Your account is immediately enabled for our Sandbox environment (https://sandbox.plaid.com). To move to Production, please request access from the Dashboard. You will need Silicon Valley Bank Production credentials prior to initiating live traffic in the Silicon Valley Bank API with Plaid.
