This topic describes how to manage the API endpoint flow nodes and the connections between nodes on the API Orchestration user interface. The procedures in this topic appear in the most probable configuration order. To manage API endpoints, refer to Manage Endpoints. To manage API endpoint flows, refer to Manage Flows.

Add nodes

To add nodes to a flow:

  1. Select the node to add to the flow from the listed nodes.
  2. Drag the selected node into the flow editor panel. The node will automatically align with any additional nodes in the flow. A warning message may be displayed and the node may be highlighted until it is configured.

Configure nodes

To configure nodes in a flow:

  1. Select a node to configure its properties.
  2. If necessary, select and change the default node name. Node naming should reflect the function of the node.
  3. Select the node method from the Method drop-down menu. For additional information on the Model and General node Method selections, refer to Flow Orchestration.
  4. Configure the node parameters. To configure the node parameters, select Parameters and complete or edit the parameter configuration entries. Note that the configurable parameter entries are dependent on the selected node method and the parameter configuration selected from Selector drop-down menu. For additional information on the Model and General node configurable parameters for each method and the configuration selections for each configurable parameter, refer to Flow Orchestration.
  5. Configure the node outputs. To configure the node outputs, select Outputs and complete or edit the output configuration entries. Note that the configurable output entries are dependent on the selected node method. For additional information on the Model and General node configurable outputs for each method, refer to Flow Orchestration. Once the node is properly configured, the warning message is longer displayed and the node is longer highlighted.

Edit nodes

To edit the configuration of a node:

  1. Select the node to edit. The configuration of the selected node will be displayed.
  2. Make the following changes as needed:
    1. Edit and change the node name.
    2. Select a different Method. For additional information on the Model and Core node Method selections, refer to Flow Orchestration.
    3. Edit the Parameters. For additional information on the Model and General node configurable parameters for each method and the configuration selections for each configurable parameter, refer to Flow Orchestration.
    4. Edit the Outputs. For additional information on the Model and General node configurable outputs for each method, refer to Flow Orchestration.
  3. Verify that no warning messages or alerts are displayed.

Connect nodes

Icon
All API endpoint flows begin with a default Start node.

Start nodes can only be connected to one other node in the flow. To connect the output of the Start node to the input of another node:

  1. Click on Start node.
  2. While leaving the Start node clicked on, move your pointer off the Start node. The output connection on Start node and the input connections on the additional nodes in the flow will be displayed. The connector from the Start node will follow the movement of the cross-hair of your pointer.
  3. Pull the connector towards the next node to include in the flow. The connector will snap to the input of the next node to include in the flow when you hover over it.
  4. To finish the connection, drop the connector on the input of the next node in the flow. The flow is automatically rearranged according to the existing connectors and nodes.

To connect the output or outputs of a node to the input of another node:

  1. Click on the output of a node to connect to the input of another node.
  2. While leaving the output of node clicked on, move your pointer off the output of the node. The output connection and the input connections on the additional nodes in the flow that can be connected with will be displayed. The connector from the output of the node will follow the movement of the cross-hair of your pointer.
  3. Pull the connector towards the next node to include in the flow. The connector will snap to the input of the next node to include in the flow when you hover over it.
  4. To finish the connection, drop the connector on the input of the next node in the flow. The flow is automatically rearranged according to the existing connectors and nodes.

Delete node connectors

To delete a node connector:

  1. Select the node connector to delete.
  2. Click the keyboard Del key or Backspace key. The selected connector is deleted and the flow is automatically rearranged according to the existing connectors and nodes.

Delete nodes

To delete nodes in a flow:

  1. Select the node to delete.
  2. Click the keyboard Del key or Backspace key. The Node delete caution screen is displayed.
  3. Click Proceed to complete the deletion of the selected node and return to the flow. Select Cancel to cancel the deletion of the selected node and return to the flow.

    Redundant

    1. I have removed the redundancies.

  5. Beginning with API Builder V3.1.0

    Not sure if that is necessary.

  6. selector or selectors

    selector(s) ?

    1. Incorporated comment.

       

  7. You may select a selector from the listed selector options or continue typing to manually configure the selector parameter.

    You may optionally choose a selector from the list, or continue typing to manually configure the parameter.

  8. Edit nodes

    This whole section with heading "Edit nodes" seems redundant.  It is very similar to "Configure nodes".  The difference being this one mentions "choosing a method", which would also be valid for "Configure nodes".

    1. Removed the redundant Edit nodes section.

  9. I have incorporated your comments.
