Stream

The POST /stream endpoint allows you to register actions on your events/tickets alongside all of their relevant metadata within GET Protocol and propagate this data to the blockchain.

The accepted actions are:

newEvent
updateEvent
soldTicket
updateTicket
resoldTicket
scannedTicket
checkedInTicket
claimedTicket
invalidatedTicket

An event must first be registered before any ticket action be accepted within that event.

Per action, the following fields are accepted:

Required Fields: all specified must be sent
Exclusive Fields: 1 required but no more than 1 accepted
Optional Fields: all can be omitted, defaults will be used (see Data Field Types table for defaults)

Null vs Empty
On event and tickets updates with eventUpdate or ticketUpdate actions respectively, you can send the default value from the table above on non required fields to have them cleared.
You can also send the json null value i.e. "imageUrl": null or completely omit fields that are not intended to be updated.

Next you can find an example payload for an event with a single ticket that went through all the possible states until being claimed by/to a ticket buyer account:

Limits & Ordering
Each request can include up to 5000 actions. Actions are processed and their result returned in the order they are sent in the request.

A request with the previous payload should yield a response similar to:

{
    "status": "success",
    "data": [
        {
            "status": "success",
