Signal is a marketing platform used by hundreds of businesses to connect and engage with their customers. You can find documentation for our API endpoints below. If you’re just getting started, be sure to read the overview of the Signal API.
We provide two sets of APIs:
Our v2 APIs are JSON based, and the v1 APIs are XML based. We strongly suggest you start with the v2 APIs as we’ll be deprecating the v1 APIs soon.
If you questions or need support, please be sure to read our support page.
If you’re a business looking for a developer to integrate with the Signal API, our friends at Matchist can you help.
