Why are test steps or BDD scripts not visible in Zephyr Scale UI when created via API?

Hello Zephyr Community,

I am automating test case creation in Zephyr Scale Cloud using the REST API. My workflow generates test cases with either “Step by Step” steps or BDD-Gherkin scripts (using testScript.type = "GHERKIN" and a “text” field).

The API call succeeds and the test case is created, but in the Zephyr UI, the “Test Script” section either shows as “Step by Step” with no steps, or as “BDD-Gherkin” with no script visible.

If I manually set the script type and paste the steps or Gherkin scenario in the UI, everything displays as expected.

Questions:

Is there a known limitation or required configuration for making test steps or BDD scripts visible in the UI when creating/updating test cases via API?

Are there any required fields or payload formats to ensure the UI displays the steps or Gherkin script?

Is there a workaround to automate this fully, or is manual intervention always required after API creation?
