This event type is available in the EventLogFile object in API version 43.0 and later. For details about event monitoring, see the [Trailhead Event Monitoring module](https://trailhead.salesforce.com/en/modules/event_monitoring/units/event_monitoring_intro "HTML (New Window)") or the [REST API Developer’s Guide](https://developer.salesforce.com/docs/atlas.en-us.264.0.api_rest.meta/api_rest/using_resources_event_log_files.htm "HTML (New Window)"). ## Fields | Field | Details | | --- | --- | | CONTINUATION\_ID | Type String Description A unique ID identifying a sequence of events within a request. Example SFDC-Continuation-14e3cg85-961d-389e-7bz1-3d171543162a | | DURATION | Type Number Description Total duration of continuation, in milliseconds. | | EVENT\_TYPE | Type String Description The type of event. The value is always ContinuationCalloutSummary. | | ORGANIZATION\_ID | Type Id Description The 15-character ID of the organization. For example: 00D000000000123. | | ORIGIN\_REQUEST\_ID | Type Id Description The ID of the request that initiated a callout. Example TID:5ILoVKlztX\_rDDJcp7 | | REQUEST\_FORM\_SIZE | Type String Description Continuation request form size, in bytes. Depending on how many HTTP requests were used in a continuation, this field can contain up to three space-separated values. | | REQUEST\_ID | Type String Description The unique ID of a single transaction. A transaction can contain one or more events. Each event in a given transaction has the same REQUEST\_ID. For example: 3nWgxWbDKWWDIk0FKfF5DV. | | RESPONSE\_SIZE | Type String Description The size of the callout response, in bytes. Depending on how many HTTP requests were used in a continuation, this field can contain up to three space-separated values. | | STATUS\_CODE | Type String Description The HTTP status or internal code returned by the remote endpoint. A status code of 200 indicates that the request was successful. Other status code values indicate the type of problem that was encountered. Depending on how many HTTP requests were used in a continuation, this field can contain up to three space-separated values. Examples - 2000—The timeout was reached, and the server didn’t get a chance to respond. - 2001—There was a connection failure. - 2002—Exceptions occurred. - 2003—The response hasn’t arrived (which also means that the Apex asynchronous callout framework hasn’t resumed). - 2004—The response size is too large (greater than 1 MB). | | SUCCESS | Type Boolean Description Indicates whether the continuation was successful (1) or not (0). | | TIMESTAMP | Type String Description The access time of Salesforce services in GMT.

For example: 00590000000I1SNIA0. | | VF\_CONTROLLER\_SIZE | Type String Description Continuation Visualforce controller size, in bytes. Depending on how many HTTP requests were used in a continuation, this field can contain up to three space-separated values. | #### See Also - [EventLogFile Supported Event Types](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_eventlogfile_supportedeventtypes.htm "The EventType field in the EventLogFile object supports these events. Some common fields, such as CPU_TIME and RUN_TIME, can have null or zero values depending on how the events are generated for a given feature. Sometimes, three quotation marks appear around event data containing special characters in the CSV file. The third quotation mark is necessary for tools and applications to parse the field data at the correct field value boundary.") - [EventLogFile](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_objects_eventlogfile.htm "Represents event log files generated by Event Monitoring.
