APIMATIC has just announced integration with Azure API Management. If you aren't familiar with APIMATIC, the company offers high-quality API SDKs generated from standard API definition formats, such as OpenAPI (formerly Swagger). With the APIMatic widget embedded into your developer portal, you can easily provide downloadable client SDKs for your APIs in API Management. SDKs are accompanied by how-to documentation and available in all the popular programming languages. And you don't have to worry about regenerating the SDKs when the underlying APIs change as they automatically stay synced with the API definitions.
