plaid-java Circle CI Maven Central

Java Bindings for the Plaid API (

The whole available Plaid API is defined in the PlaidApiService interface.

Check the Junit test classes for examples of more use cases. Every API endpoint has at least one integration test against the sandbox environment.

Uses Retrofit and OkHttp under the hood. You may want to take a look at those libraries if you need to do anything out of the ordinary.


Plaid-java is available at Maven Central



Each major version of plaid-java targets a specific version of the Plaid API:

API version plaid-java release

Basic Usage

// Use builder to create a client
PlaidClient plaidClient = PlaidClient.newBuilder()
  .clientIdAndSecret("your_client_id", "your_secret")
  .publicKey("your_public_key") // optional. only needed to call endpoints that require a public key
  .sandboxBaseUrl() // or equivalent, depending on which environment you're calling into

// Synchronously exchange a Link public_token for an API access_token
// Required request parameters are always Request object constructor arguments
Response<ItemPublicTokenExchangeResponse> response = plaidClient.service()
    .itemPublicTokenExchange(new ItemPublicTokenExchangeRequest("the_link_public_token")).execute();

if (response.isSuccessful()) {
  accessToken = response.body().getAccessToken();

// Asynchronously do the same thing. Useful for potentially long-lived calls.
    .itemPublicTokenExchange(new ItemPublicTokenExchangeRequest(publicToken))
    .enqueue(new Callback<ItemPublicTokenExchangeResponse>() {
        public void onResponse(Call<ItemPublicTokenExchangeResponse> call, Response<ItemPublicTokenExchangeResponse> response) {
          if (response.isSuccessful()) {
            accessToken = response.body.getAccessToken();

        public void onFailure(Call<ItemPublicTokenExchangeResponse> call, Throwable t) {
          // handle the failure as needed

// Decoding an unsuccessful response
try {
  ErrorResponse errorResponse = plaidClient.parseError(response);
} catch (Exception e) {
  // deal with it. you didn't even receive a well-formed JSON error response.

Legacy API

If you're looking for a Java client that works with the legacy Plaid API, use versions of plaid-java before 2.1.0. The API and client are not backwards-compatible.
