Send MAM Message

Sending Masked Authenticated Message

Masked Authenticated Message let you create a channel and publish message stream within. In this API, tangle-accelerator provides user ability to create a unique channel stream and broadcast a message whose size can be bigger than one transaction. After the MAM bundle has been wrapped up, tangle-accelerator will broadcast it to the tangle and return the bundle hash and channel id back to users. Header of Content-Type with application/json is required.
