[Plaid Documentation](

## Usage

Add to your dependencies in `mix.exs`. The hex specification is required.

def deps do
  [{:plaid, "~> 1.2", hex: :plaid_elixir}]

## Configuration

All calls to Plaid require either your client id and secret, or public key. Add the
following configuration to your project to set the values.

config :plaid,
  root_uri: ""
  client_id: "your_client_id",
  secret: "your_secret",
  public_key: "your_public_key",
  httpoison_options: [timeout: 10_000, recv_timeout: 30_000]

By default, `root_uri` is set by `mix` environment. You can override it in your config.
- `dev` -
- `prod`-

Finally, you can pass in custom configuration for [HTTPoison]( It's recommended you
extend the receive timeout for Plaid, especially for retrieving historical transactions.

## Obtaining Access Tokens

Access tokens are required for almost all calls to Plaid. However, they can only be obtained
using [Plaid Link](

Once a user successfully connects to his institution using Plaid Link, a
public token is returned to the client. This single-use public token can be exchanged
for an access token and item id (both of which should be stored) using

Consult Plaid's documentation for additional detail on this process.

## Compatibility

As of version `1.2`, this library natively supports serialization of its structs using `Jason` for compatibility with Phoenix.

## Tests and Style

This library uses [bypass]( to simulate HTTP responses from Plaid.
