Amazon Connect service quotas
All service quotas can be adjusted/increased unless otherwise noted.
Your AWS account has default quotas, formerly referred to as limits, for each AWS service.
To request a quota increase, see Requesting a quota
increase in the Service Quotas User Guide. If the quota is not yet
available in Service Quotas, use the Amazon Connect service quotas increase form
Important things to know
-
You must create your instance before you can request a service quota increase.
-
It can take up to a few weeks to increase your service quota. If you're increasing your quotas as part of a larger project, be sure to add this time to your plan.
-
Use the same form to submit a request to port your US phone number from your current carrier to Amazon Connect. For more information about porting phone numbers, see Port your current phone number.
-
The quotas apply per AWS Region. You can have multiple Amazon Connect instances in each Region. It's possible to raise quotas for all instances in a Region.
-
This documentation describes the default quotas for new accounts. Because the quotas have been adjusted over time, the default values for your account might be different than the default values described here.

Derive Concurrent post-call analytics jobs based on your Amazon Connect call volume
A post-contact (call or chat) analytics job is kicked off after the completion of each contact with Contact Lens enabled. The time to complete a post-contact analytics job is about 40% of the call length. To calculate concurrent post-call analytics jobs, use the following formula:
(average call duration in minutes) * (0.4) * (calls per hour) /
(60)
The following table shows some examples.
| Average call duration (in minutes) | Calls per hour* | Approximate Concurrent post-call jobs |

How contacts are counted
The following contacts are counted:
-
Handled by a flow
-
Waiting in queue
-
Handled by an agent
-
Outbound call
The following contacts are not counted:
-
Callbacks waiting in a callback queue are not counted until the callback is offered to an available agent.
-
External transfers
If the quota for concurrent active calls per instance is exceeded, contacts get a reorder tone (also known as a fast busy tone), which indicates that there is no available transmission path to the called number.
You can calculate your configured quota using CloudWatch metrics. For instructions, see Use CloudWatch metrics to calculate concurrent call quota.
If you're only taking calls you can also determine your concurrent calls quota by editing a queue and entering an exceptionally large number for the contact limit. The resulting error message displays your quota for concurrent calls. For example, in the following image, it shows the call quota for that instance is 9.
API throttling quotas
Amazon Connect API throttling quotas
Amazon Connect throttling quotas are by account, and per Region, not by user and not by instance. For example:
-
If different IAM users from the same account make requests, they are sharing a throttle bucket.
-
If multiple requests are sent from different instances from the same account, they are also sharing a throttle bucket.
When you use the Amazon Connect Service API , the number of requests per second is limited to the following:
-
For the GetMetricData and GetCurrentMetricData operations, a RateLimit of 5 requests per second, and a BurstLimit of 8 requests per second.
Note The rate limit cannot be increased for GetMetricData and GetCurrentMetricData.
-
For StartChatContact, StartContactStreaming, StopContactStreaming, a RateLimit of 5 requests per second, and a BurstLimit of 8 requests per second.
-
For all other operations, a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.
Amazon Connect Participant Service API throttling quotas
For the Amazon Connect Participant Service, the quotas are by instance.
When you use the Amazon Connect Participant Service API, the number of requests per second is limited to the following:
-
CreateParticipantConnection: a RateLimit of 6 requests per second, and a BurstLimit of 9 requests per second.
-
DisconnectParticipant: a RateLimit of 3 requests per second, and a BurstLimit of 5 requests per second.
-
GetTranscript: a RateLimit of 8 requests per second, and a BurstLimit of 12 requests per second.
-
SendEvent and SendMessage: a RateLimit of 10 requests per second, and a BurstLimit of 15 requests per second.
-
StartAttachmentUpload: a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.
-
CompleteAttachmentUpload: a RateLimit of 2 requests per second, and a BurstLimit of 5 requests per second.
-
GetAttachment: a RateLimit of 8 requests per second, and a BurstLimit of 12 requests per second.
Amazon Connect Contact Lens Service API throttling quotas
Amazon Connect Contact Lens throttling quotas are by account, not by user and not by instance. For example:
-
If different IAM users from the same account make requests, they are sharing a throttle bucket.
-
If multiple requests are sent from different instances from the same account, they are also sharing a throttle bucket.
When you use the Amazon Connect Contact Lens API, the number of requests per second is limited to the following:
-
ListRealtimeContactAnalysisSegments: a RateLimit of 1 request per second, and a BurstLimit of 2 requests per second.
