Plaid is an API that allows you to get info easily about transactions/balances on your credit card. Jarvis leverages Plaid's legacy API

To use Plaid in Jarvis you must:

Sign up on the Plaid website. You only need a developer account as long as you have less than 100 credit cards you wish to check.
For each of your credit cards, you must first authenticate with Plaid. Here are the steps:
- Get a list of bank/credit card institutions

curl -X GET \
  https://tartan.plaid.com/institutions \
  -H 'content-type: application/json'

- Submit your credentials (auth call) to Plaid for your credit card

curl -X POST \
  https://tartan.plaid.com/auth \
  -H 'content-type: application/x-www-form-urlencoded' \
  -d 'client_id=CLIENT_ID&secret=CLIENT_SECRET&username=BANK_USERNAME&password=YOUR_PASSWORD&type=YOUR_BANK_CARD'

- Upgrade your account on Plaid so that you can hit the transactions endpoint

curl -X POST \
https://tartan.plaid.com/upgrade \
-H 'content-type: application/x-www-form-urlencoded' \
-d 'client_id=CLIENT_ID&secret=CLIENT_SECRET&access_token=YOUR_ACCESS_TOKEN&upgrade_to=connect'

- Get your transactions (you don't need to do this in Jarvis, as Jarvis does this for you)

curl -X POST \
https://tartan.plaid.com/connect/get \
-H 'content-type: application/x-www-form-urlencoded' \
-d 'client_id=CLIENT_ID&secret=CLIENT_SECRET&access_token=YOUR_ACCESS_TOKEN'```

Save the token returned from the auth call as a record in the plaid_banks table in your DB. You can give the name value whatever you would like to call your bank.

pb = PlaidBank.new
pb.name = "Chase"
pb.token = "AUTH_TOKEN"
pb.save!
