Connect any API to your smart contract, and how it works – Chainlink Engineering Tutorials

Smart contracts need to be able to connect to real world data & APIs. Chainlink is the middleware that enables blockchain to be connected to the real world. This video describes how to get data from httpget requests, httppost requests, and a number of other methods into your smart contract. It also goes into exactly how it plays out on the Ethereum chain.

Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments. Chainlink is critical to connecting the blockchain ecosystem to the rest of the world.
