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/[email protected]

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. 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 <item-id-or-alias>. - Alias: plaid-cli alias <item-id> <name>, list with plaid-cli aliases.

Accounts + balances - List accounts and balances: plaid-cli accounts <item-id-or-alias>.

Search transactions - Pull a date range as JSON, then filter locally: - plaid-cli transactions <item-id-or-alias> --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: bash 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"
