Service integration is a common problem for every business of sufficient size, regardless of industry. Whether you run a hotel chain, restaurant, or an airline, you always want to consume services (such as mass email, CRM, and campaign management) based on your specific business domain. Because Wix is a general-purpose web hosting platform, we host a very diverse set of businesses, and we partner with third-party providers to offer services that aren’t part of our core platform. Over time, we’ve evolved a service integration model to tackle these requirements.

Join me for a guided tour through the evolution of our architecture, from our initial ideas and goals, to our various design and technology challenges, which ultimately resulted in our inter-app communication API. I will also discuss restrictive aspects such as backwards compatibility and API conformance and standards.
