Many card fields are ordinary Client Config settings that are simply grouped by service on the Integrations page. You will find the same values in Business Settings > Configuration under these tabs: Marketing: Analytics (Facebook Pixel, Google Analytics, Google Tag Manager, Google Tag, Adwords tracking number and conversion label, Google/Bing Webmaster codes), Business: Integrations (Google Recaptcha version), Business: Email (System Email From/Name/BCC and Disable Email Validation Security), Newsletter: Popup (all popup form settings), Business: Cart (Enable Custom Tax Calculation Systems, Cart - Enable in house delivery fallback) and Root Planner (API Token, Webhook Secret). Keys such as Klaviyo, Yelp, Trustpilot, Instagram, Uber Direct and Shippo are only editable on the Integrations page. Changing a value in either place updates the other, since both read and write the same underlying setting.
