Workflow ION API call

• You can use a new workflow step named “ION API” to model an API call at any place in the workflow.
• You can call an ION API operation that is exposed through the ION API metadata. Reply of type JSON, XML, and Text is accepted
• You can use both, reading and writing operations.
• You can search for the operation to use based on the ION API metadata. The ION API Gateway applies an elastic search algorithm.
• You can configure the security credentials for each workflow ION API step by importing a service account.
• You can map between API request and API output parameters and workflow parameters.
• You can pass workflow structures and task notes as request body for POST and PUT methods, which support these data structures.
• You can test the API execution during modeling.
• You can configure preferences for error handling.

These features are not supported:

• Reply of REST Streaming Methods
• Input parameters of type FORMDATA and input content type “multipart/form-data". Only parameters of type FORMDATA and input content type “application/x-www-form-urlencoded” are supported. If the input content type is not specified, it is assumed the type is "application/x-www-form-urlencoded".

To model a workflow that makes an ION API call, start ION Desk and navigate to the workflow modeler. Add a workflow step of type ION API and specify its properties as described later. When the configuration is ready, save and activate the workflow.

See Specifying details for an ION API element.

To call an API, these configuration steps must be completed:

• Ensure the application that exposes the ION API to call is registered and its endpoints are indexed.

  See “Registering the client application” in the Infor ION API Administration Guide.

• In the Infor Ming.le User Management UI, create service accounts for the backend application that exposes the ION APIs to call. Ensure to specify the description property of the service account, as this is required by ION.

  See “Service Accounts” in the Infor Ming.le Cloud Edition Administration Guide.
