To consume data from a topic, use the following request syntax:

{
"aggregated": <value>
}

Where

<value>

takes one of the following values:

true. The subscription consumes all the available publications in each API call.
false. The subscription consumes only the oldest publication in each API call.

{
"aggregated": true
}

When you run multiple publications, you can add the publication event ID of a specific publication to the request body to consume only the data of the specific publication event. You can add only one publication event ID to the request body. The key

"publicationEventId"

is case sensitive. If you don't add the publication event ID of a specific publication to the request body, the subscription consumes all the available publication events.

{
			"publicationEventId" : "<publicationEventId>"
}  

{
			"publicationEventId" : "594210"
}  

To reconsume data that had previously been processed, use the following request syntax:

{
			"requestType" : "RECONSUME",
			"eventId" : "<subscriptionEventId>"
}  

Where the key

"eventId"

is the subscription event ID to reconsume.

{
			"requestType" : "RECONSUME",
			"eventId" : "40559"
}  

To reprocess a failed subscription, use the following request syntax:

{
			"requestType" : "REPROCESS",
			"eventId" : "<subscriptionEventId>"
}  

Where the key

"eventId"

is the subscription event ID to reprocess.

{
			"requestType" : "REPROCESS",
			"eventId" : "40577"
}
