Can you add the Vend API to this list as well please?

[dougbu]

@Yusha813 you've already opened an issue about supporting the Vend API. Testing should be added as part of #289 or after that work is done. There's no action to take here in the meantime.

Suggest we un-assign this issue, remove the Mapped to Big Rock label, and move it to the 1.0.0-preview3 milestone
