Plaid

Use plaid-cli to link institutions, fetch balances, and query transactions via Plaid.
Do not print or log secrets (client id, secret, access tokens).

Install

• go install github.com/jverdi/plaid-cli@0.0.2

Setup

• Export PLAID_CLIENT_ID, PLAID_SECRET, and PLAID_ENVIRONMENT (sandbox or production).


• Optional: PLAID_LANGUAGE (en, fr, es, nl), PLAID_COUNTRIES (US, CA, GB, IE, ES, FR, NL).


• Optional config file: ~/.plaid-cli/config.toml.

[plaid]
  client_id = "..."
  secret = "..."
  environment = "sandbox"

• Data directory: ~/.plaid-cli (stores tokens and aliases).

Link + aliases

• Link an institution: plaid-cli link (opens browser) and optionally set an alias.


• Relink: plaid-cli link .


• Alias: plaid-cli alias , list with plaid-cli aliases.

Accounts + balances

• List accounts and balances: plaid-cli accounts .

Search transactions

• Pull a date range as JSON, then filter locally:

- plaid-cli transactions --from 2024-01-01 --to 2024-01-31 --output-format json
- jq -r '.[] | select(.name | test("grocery"; "i")) | [.date, .name, .amount] | @tsv'

• Use --account-id from accounts output to narrow results.


• Output formats: json or csv.

Monitor transactions

• Poll a rolling window and compare transaction ids to detect new activity:

state=/tmp/plaid.txids
  next=/tmp/plaid.txids.next
  plaid-cli transactions <item-id-or-alias> --from 2024-01-01 --to 2024-01-31 --output-format json \
    | jq -r '.[].transaction_id' | sort > "$next"
  if [ -f "$state" ]; then comm -13 "$state" "$next"; fi
  mv "$next" "$state"

• Use cron for scheduling.

Notes

• Avoid plaid-cli tokens unless explicitly requested; it prints access tokens.


• Relink is auto-triggered on ITEM_LOGIN_REQUIRED errors.

Recognize requests such as:

• "Search transactions for Starbucks last month"


• "Show balances for my Chase accounts"
