How to register a license key

info

For more information on obtaining a license key, please visit this page.

Once you have received your key, register it using the integration approach that your application uses.

Workflow Engine Core​

If you use Workflow Engine Core directly and create WorkflowRuntime manually, register the license key in WorkflowRuntime:

WorkflowRuntime.RegisterLicense("your license key text");

Workflow Engine Web API​

If you use Workflow Engine Web API, add the license key in Program.cs when configuring WorkflowApiCoreOptions:

builder.Services.AddWorkflowApiCore(SetupWorkflowApiCore);

void SetupWorkflowApiCore(WorkflowApiCoreOptions options)
{
options.LicenseKey = "Put your license key here";
}
important

For Workflow Engine Core, this code must be executed before starting Workflow Engine.

The license key string must include the prefix of the company name or the prefix "TRIAL-".
