FAQPage Schema

How do I integrate external REST APIs into Mendix microflows?▼

To integrate external REST APIs in Mendix microflows, generate REST clients directly from OpenAPI 3.0 specifications or define manual REST client documents for reusable service calls. This handles JSON data mapping and secure authentication within your Mendix application.

Can I generate a Mendix REST client from an OpenAPI specification?▼

Yes, you can instantly generate Mendix REST clients from OpenAPI 3.0 specifications. This automation saves development time by standardizing external service connections and handling dynamic API calls within your microflows.

What is the best way to map complex JSON responses to Mendix entities?▼

The best way to map complex JSON responses to Mendix entities is using built-in JSLT support. It efficiently cleans and transforms external REST service data into structured Mendix entities for robust service-oriented architecture.

Does Mendix support inline HTTP calls for quick API prototyping?▼

Mendix supports inline HTTP calls for quick, one-off API prototyping. You can choose between these inline calls for rapid testing or structured REST client documents for managing reusable external services in your microflows.

How do I handle secure authentication for REST service integrations in Mendix?▼

Handling secure authentication for REST service integrations in Mendix involves using the standardized patterns provided by REST client documents. These ensure robust service-oriented architecture and efficient data serialization for external API calls.
