# LookupEvents
Looks up [management events](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-concepts.html#cloudtrail-concepts-management-events) or [CloudTrail Insights events](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-concepts.html#cloudtrail-concepts-insights-events) that are captured by CloudTrail. You can look up events that occurred in a Region within the last 90 days.
**Note**
`LookupEvents` returns recent Insights events for trails that enable Insights. To view Insights events for an event data store, you can run queries on your Insights event data store, and you can also view the Lake dashboard for Insights.
Lookup supports the following attributes for management events:
+ AWS access key
+ Event ID
+ Event name
+ Event source
+ Read only
+ Resource name
+ Resource type
+ User name
Lookup supports the following attributes for Insights events:
+ Event ID
+ Event name
+ Event source
All attributes are optional. The default number of results returned is 50, with a maximum of 50 possible. The response includes a token that you can use to get the next page of results.
**Important**
The rate of lookup requests is limited to two per second, per account, per Region. If this limit is exceeded, a throttling error occurs.
## Request Syntax
```
{
"EndTime": number,
"EventCategory": "string",
"LookupAttributes": [
{
"AttributeKey": "string",
"AttributeValue": "string"
}
],
"MaxResults": number,
"NextToken": "string",
"StartTime": number
}
```
## Request Parameters
For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).
The request accepts the following data in JSON format.
** [EndTime](#API_LookupEvents_RequestSyntax) **
Specifies that only events that occur before or at the specified time are returned. If the specified end time is before the specified start time, an error is returned.
Type: Timestamp
Required: No
** [EventCategory](#API_LookupEvents_RequestSyntax) **
Specifies the event category. If you do not specify an event category, events of the category are not returned in the response. For example, if you do not specify `insight` as the value of `EventCategory`, no Insights events are returned.
Type: String
Valid Values: `insight`
Required: No
** [LookupAttributes](#API_LookupEvents_RequestSyntax) **
Contains a list of lookup attributes. Currently the list can contain only one item.
Type: Array of [LookupAttribute](API_LookupAttribute.md) objects
Required: No
** [MaxResults](#API_LookupEvents_RequestSyntax) **
The number of events to return. Possible values are 1 through 50. The default is 50.
Type: Integer
Valid Range: Minimum value of 1. Maximum value of 50.
Required: No
** [NextToken](#API_LookupEvents_RequestSyntax) **
The token to use to get the next page of results after a previous API call. This token must be passed in with the same parameters that were specified in the original call. For example, if the original call specified an AttributeKey of 'Username' with a value of 'root', the call with NextToken should include those same parameters.
Type: String
Required: No
** [StartTime](#API_LookupEvents_RequestSyntax) **
Specifies that only events that occur after or at the specified time are returned. If the specified start time is after the specified end time, an error is returned.
Type: Timestamp
Required: No
## Response Syntax
```
{
"Events": [
{
"AccessKeyId": "string",
"CloudTrailEvent": "string",
"EventId": "string",
"EventName": "string",
"EventSource": "string",
"EventTime": number,
"ReadOnly": "string",
"Resources": [
{
"ResourceName": "string",
"ResourceType": "string"
}
],
"Username": "string"
}
],
"NextToken": "string"

The following data is returned in JSON format by the service.
** [Events](#API_LookupEvents_ResponseSyntax) **

** [NextToken](#API_LookupEvents_ResponseSyntax) **
The token to use to get the next page of results after a previous API call. If the token does not appear, there are no more results to return. The token must be passed in with the same parameters as the previous call. For example, if the original call specified an AttributeKey of 'Username' with a value of 'root', the call with NextToken should include those same parameters.
Type: String
