Configuration requirements to develop SPL2-based applications
To develop SPL2-based apps, you must configure your development environment.
Development environment alternatives
Splunk recommends using Visual Studio Code with the Splunk extension for the best experience. See Set up the Splunk Extension for Visual Studio (VS) Code.
If you decide to develop directly using Splunk APIs, use any API client that you wish to such as Postman. For information about the SPL2-based endpoints, see the Search endpoint descriptions section in the Splunk Enterprise REST API Reference Manual.
Port 9800
The platform versions that support SPL2 use port 9800 to connect to the Splunk data orchestrator. The Splunk data orchestrator is a new software component that parses and routes SPL2 modules to splunkd. If for some reason port 9800 is not available, you can designate another port to connect to the data orchestrator. See Edit the SPL2 configuration.
