Verified steps

POST /link/token/create with user.client_user_id, products=['transactions'], country_codes
Open Plaid Link client-side with the link_token; receive public_token on success
POST /item/public_token/exchange to get a persistent access_token
POST /transactions/sync with the access_token; persist next_cursor and page until has_more=false

Known gotchas

/transactions/get is legacy — use /transactions/sync with cursor pagination
Initial sync is async: handle SYNC_UPDATES_AVAILABLE webhook rather than polling immediately
access_tokens never expire but break when the user changes bank credentials — handle ITEM_LOGIN_REQUIRED with update-mode Link
