I could not find any request to add an attachment to an existing test cycle or to test execution in the documentation https://support.smartbear.com/zephyr-scale-cloud/api-docs/.
Any ideas whether I can add attachments using the API?
Champion Level 3I've never done it but adding attachments to a test case, test cycle or test execution certainly seems possible with the Server API (if that's what you have): Zephyr Scale Server API (v1) (smartbear.com)
- note, test execution in the server version is called /testresult
But the cloud version of the API doesn't seem to have an attachment option. Can I suggest you contact SmartBear support and ask them the question if that's what you're looking for.
