If your platform is not listed and it supports Open API (Swagger) extensions, import the API Definition document from the Developer Edition product on our Customer Portal at https://portal.apptigent.com/product (look for the Open API link at the top of the PowerTools Developer API definition page). Invoke the desired actions in your app or workflow design tool, supplying values for the listed parameters. Refer to the developer documentation on the Customer Portal for details on input and output formats.
If you are developing a custom app, execute a RESTful POST operation to the /CountCollection endpoint in your application code or use the pre-generated client scaffolding from our Github repo at https://github.com/apptigent/powertools. Be sure to include your API Key (Client ID) in the header using the “X-IBM-Client-Id” key/value pair. The body should be a well-formed JSON object with the parameter label(s) and value(s) in the specified format. Refer to the API documentation at https://portal.apptigent.com for more information.
