Node Generator

Integrate Web APIs into KNIME

Node Generator for Web APIs is your free data integration tool to connect KNIME with your public or private REST-based service. The Node Generator converts any OpenAPI or Swagger-based specification, including documentation, schemas, validation, and more into a set of easily distributable and accessible KNIME nodes, ready to be consumed within your users’ workflows.

Say goodbye to the hassles of deciphering complex API documentations and make all the functionality available right at your fingertips. Build the KNIME nodes within seconds from a given YAML or JSON specification – no matter if you have five or five hundreds of API operations.

Profit from NodePit’s passion, love for detail, and a decades of experience of building service integrations for a broad landscape of services. Start using the Node Generator for free – get in touch:
