Asset Broadcast Sponsor


I am trying to publish signed Sponsor Asset Fee transaction using /assets/broadcast/sponsor. However I keep getting 404 error.

I have created signature for my sponsorship (using: version, senderPublicKey, assetId, minSponsoredAssetFee, fee, timestamp) and put it inside “proofs” field. What is wrong in my request?

Thanks for pointing this out. Please try posting the same json to /transactions/broadcast. We’ll fix this in the next release.

I’ve tried posting the same request + ‘type:14’ and it works perfectly.
I think it should be mentioned in the docs (
that we can also use transactions/broadcast to initiate sponsorship although it may seem obvious for some people who are familiar with waves API.
