When is creating new component, updating, i have suggestion to have possiblity to do this with json
We’ve considered a file format for downloading or uploading/importing flows, which is what I’m assuming you’re asking for here. It would likely be something a little more compact than JSON (given that flows can be quite large and we’d want to support versioning and additions to the format), but I believe it is on the roadmap.
If you’re asking for a HTTP API, that isn’t planned - flows are very complex and creating them over a HTTP API with scripts or similar isn’t something we want to support.
