The POST /stream endpoint allows you to register actions on your events/tickets alongside all of their relevant metadata within OPEN Ticketing 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)

action	required fields	exclusive fields	optional fields
`newEvent`	`eventId` `currency`		`eventName` `shopUrl` `coverImageUrl` `coverMediaUrl` `defaultNftImageUrl` `defaultNftMediaUrl` `latitude` `longitude` `startTime` `endTime` `callbackUrl`
`updateEvent`	`eventId`		`eventName` `currency` `shopUrl` `coverImageUrl` `coverMediaUrl` `defaultNftImageUrl` `defaultNftMediaUrl` `latitude` `longitude` `startTime` `endTime` `callbackUrl`
`soldTicket`	`eventId` `ticketId` `userId` `price`		`imageUrl` `mediaUrl` `orderTime` `to` `metadataAttributes` `name` `description`
`updateTicket`		`ticketId` `nftId`	`imageUrl` `mediaUrl` `metadataAttributes`
`resoldTicket`	`userId` `price`	`ticketId` `nftId`	`orderTime` `to`
`scannedTicket`		`ticketId` `nftId`	`orderTime`
`checkedInTicket`		`ticketId` `nftId`	`orderTime`
`claimedTicket`	`to` or `userId` (both also accepted)	`ticketId` `nftId`	`orderTime`
`invalidatedTicket`		`ticketId` `nftId`	`orderTime`

Note: On resoldTicket actions, the userId should represent the user that has just bought the ticket. It must be a different user identifier from the user that held the ticket previous to the resale (sent in the previous soldTicket or resoldTicket action for that ticket)

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.

Data Field Details

data field	detail
`eventId`	Event ID reference, created by the api caller, to indicate how this event is referenced in all stream requests where it is required. For example, if you send a `newEvent` request with the field `eventId="test-event"`, then a `soldTicket` request with the field `eventId="test-event` will mint tickets on that newly created event. This field must be unique per api caller.
`eventName`	The name of the event, created by the api caller. This name will be publicly available.
`currency`	The main currency used to sell the tickets for this event. All `price` fields sent will be assumed to be in this currency.
`shopUrl`	The url for the main shop/page where tickets where sold from.
`coverImageUrl`	The main cover image url for the event. E.g. a `.jpg` url
`coverMediaUrl`	The main cover media url for the event. E.g. a `youtube.com` or `.mp4` url
`defaultNftImageUrl`	The image url to use on all tickets minted for the event, if the ticket itself doesn't specify one.
`defaultNftMediaUrl`	The media url to use on all tickets minted for the event, if the ticket itself doesn't specify one.
`latitude`	The latitude where the event will take place.
`longitude`	The longitude where the event will take place.
`startTime`	The unix timestamp of when the event will start.
`endTime`	The unix timestamp of when the event will end.
`callbackUrl`	The url where GETProtocol should send callbacks to. This url must be publicly reachable without authentication and should return a 200 OK on successful processing of a callback. See Callbacks for more detail on the sent callbacks and their data.
`ticketId`	Ticket ID reference, created by the api caller, to indicate how this ticket is referenced in all stream requests where it is required. For example, if you send a `soldTicket` request with the field `ticketId="test-ticket"`, then an `invalidateTicket` request with the field `ticketId="test-ticket"` will invalidate the newly created ticket. This field must be unique per api caller.
`userId`	User Id reference, created by the api caller, to indicate to which user the ticket refers to.
`nftId`	GETProtocol generated NFT Id. This field can be used, as an alternative to `ticketId`, to identify the ticket the request refers to in the case that the api caller doesn't have the `ticketId` available. This field is generated by GETProtocol and is publicly available on the blockchain.
`imageUrl`	The main image url for the ticket. E.g. a `.jpg` url.
`mediaUrl`	The main media url for the ticket. E.g. a `youtube.com` or `.mp4` url.
`price`	The price the ticket was sold for.
`orderTime`	The unix timestamp of when the ticket was sold.
`to`	The user owned custom wallet address. This field should only be used whenever the api caller knows the wallet address of the user the ticket was sold or resold to. In case the api caller wants to let the tickets be minted to a new user wallet, this field should not be sent.
`metadataAttributes`	Additional metadata attributes of the ticket. For more details on how these metadata attributes should be constructed for proper display in OpenSea, please check this page.
`metadataTemplateId`	The id for a metadate template created within the NFT studio. Attributes specified within metadataAttributes will override attributes generated from a specified template
`name`	The name of the ticket, created by the api caller. This name will be publicly available.
`description`	The description of the event, created by the api caller. This name will be publicly available

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:

Save the promise
Each successful action request will return you an actionPromise. Save it on your data model such that you can use it later to query for each action request status.
