Gas APIs
Find out about our gas application programming interface (API) services, who can use them, and how to apply.
What are gas APIs?
Our gas application programming interfaces (gas APIs) are tools designed to improve the supplier switching process.
APIs enable companies to open up their applications’ data and functionality to other businesses. Our APIs are tailored for the gas market, so customers such as gas Suppliers can gain access to consumer use data.
This helps them provide a better experience for people who are looking to switch their gas supply.
