Foundry processing

Foundry sends HTTP requests across to the VoltScript runtime for processing. The approach is the same for preprocessors, integration services and postprocessors.

    autonumber
    UI->>Foundry: REST service request
    Foundry->>Foundry: Convert context to JSON
    Foundry->>VoltScript: Send HTTP request with Foundry context
    VoltScript->>VoltScript: Process custom VoltScript code
    VoltScript->>Foundry: Send result JSON object
    Foundry->>Foundry: Parse response and continue, if appropriate
    Foundry->>UI: Send response / error

Note

Preprocessors and postprocessors cannot be added to a VoltScript Integration Service in Foundry. Instead, add the relevant validation or manipulation in the main VoltScript Integration Service code. This will minimize the processing time.

If VoltMxResult.setErrorMessage() is called, an error is returned from the Integration Service and no further steps in the process will be performed. So the processing is:

    Foundry->>UI: Send response
    end
    Foundry->>is: Trigger main integration service
    is->>Foundry: Send result
    Foundry->>is: Trigger postprocessor
    is->>Foundry: Send result
    Foundry->>UI: Send response
