Create modifier in Square
POS API · write, waits for approval · 100% field coverage
Your agent can create modifier in Square through Apideck's POS API, the same call it makes for every POS app. It changes data in the customer's Square account, so it stops with the exact request until a person approves it. Apideck adds the customer's Square credentials, so no token ever reaches the agent.
