multiRequest

Description

In order to reduce the number of round-trips to Kaltura server, when required to perform few API calls, Kaltura API offers a multiRequest service.

Using that service, you can pass multiple requests in one REST request and you are returned with array of results, where each element is a result of one of your requests.

The multiRequest service also allows you to send sequential requests where one request can depend on one of its preceding requests.

Example

Following is example for 2 sequential requests that are independant.

	Request URL: api_v3/index.php?service=multirequest&action=null
	POST variables:
		1:service=baseEntry
		1:action=get
		1:version=-1
		1:entryId=0_zsadqv3e
		2:service=mixing
		2:action=getReadyMediaEntries
		2:mixId=0_zsadqv3e
		2:version=-1
		ks={ks}

For creating a dependant requests, you can use the following pattern as input in the variable that you want to have its value replaced with a result from a preceding request

{num:result:porpertyName}

Where:

• num - is the number of the request of which you would like to collect data from
• :result: - tells Kaltura API that it should replace this value with a result from another request
• properyName - is the property to take from the object of the required result

Example for a dependant request:

	Request URL: api_v3/index.php?service=multirequest&action=null
	POST variables:
		1:service=media
		1:action=list
		1:filter:nameLike=myentry
		2:service=media
		2:action=get
		2:entryId={1:result:objects:0:id}
		ks={ks}

In the above example, the first request will list entries that their name is like 'myentry'.
media.list request is returning an object of type KalturaMediaListResponse which contains an object named 'objects' of type KalturaMediaEntryArray

The second request is media.get which suppose to get entryId as input.

In this example, the entryId input is dynamic, and will be fetched from the first request. Since media.list response is constructed of array object within a response object, the first property we want to access is KalturaMediaEntryArray
In that array we want to take the first element (index 0), so we added ':0' to the request value. Out of the first element, we want only the ID because that is the input we want for the second request, so we added ':id'
