Amazon Chime SDK Service Level Agreement

Last Updated: November 18, 2022

This Amazon Chime SDK Service Level Agreement (“SLA”) is a policy governing the use of Amazon Chime SDK and applies separately to each account using Amazon Chime SDK. In the event of a conflict between the terms of this SLA and the terms of the AWS Customer Agreement or other agreement with us governing your use of our Services (the “Agreement”), the terms and conditions of this SLA apply, but only to the extent of such conflict. Capitalized terms used herein but not defined herein shall have the meanings set forth in the Agreement.

Service Commitment

AWS will use commercially reasonable efforts to make Amazon Chime SDK available with the Monthly Uptime Percentages in each AWS Region as set forth in the table below during any monthly billing cycle (the "Service Commitment"). In the event the Amazon Chime SDK does not meet the Service Commitment, you will be eligible to receive a Service Credit as described below.

Service Credits

Service Credits are calculated as a percentage of the total charges paid by you for Amazon Chime SDK in the affected AWS region for the monthly billing cycle in which the Service Commitment was not met, in accordance with the schedule below:

Monthly Uptime Percentage Service Credit Percentage
With a completed AWS Well-Architected Review,
Less than 99.99% but greater than or equal to 99.9%
Less than 99.9% but greater than or equal to 99.0% 10%
Less than 99.0% but greater than or equal to 95.0% 25% 
Less than 95.0% 100%

We will apply any Service Credits only against future Amazon Chime SDK payments otherwise due from you. At our discretion, we may issue the Service Credit to the credit card you used to pay for the billing cycle in which the lack of Availability occurred. Service Credits will not entitle you to any refund or other payment from AWS. A Service Credit will be applicable and issued only if the credit amount for the applicable monthly billing cycle is greater than one dollar ($1 USD). Service Credits may not be transferred or applied to any other account. Unless otherwise provided in the Agreement, your sole and exclusive remedy for any unavailability, non-performance, or other failure by us to provide Amazon Chime SDK is the receipt of a Service Credit (if eligible) in accordance with the terms of this SLA.

Credit Request and Payment Procedures

To receive a Service Credit, you must submit a claim by opening a case in the AWS Support Center. To be eligible, the credit request must be received by us by the end of the second billing cycle after which the incident occurred and must include:

  1. the words “SLA Credit Request” in the subject line;
  2. the billing cycle and AWS region(s) with respect to which you are claiming Service Credits, together with the Monthly Uptime Percentage for that AWS region for the billing cycle and the specific dates, times, and Availabilities for each 5-minute interval with less than 100% Availability in that AWS region throughout the billing cycle; and
  3. your Request logs that document the errors and corroborate your claimed outage (any confidential or sensitive information in these logs should be removed or replaced with asterisks).

If the Monthly Uptime Percentage of such request is confirmed by us and is less than the Service Commitment, then we will issue the Service Credit to you within one billing cycle following the month in which the request occurred. Your failure to provide the request and other information as required above will disqualify you from receiving a Service Credit.

Amazon Chime SDK SLA Exclusions

The Service Commitment does not apply to any unavailability, suspension, or termination of Amazon Chime SDK, or any other Amazon Chime SDK performance issues: (i) caused by factors outside of our reasonable control, including any force majeure event, telecom carrier or Internet access or related problems beyond the demarcation point of Amazon Chime SDK (e.g. firewall, router, switch, telecom circuits); (ii) that result from any actions or inactions by you or any third party (e.g. exceeding service quotas, misconfiguring security groups, VPC configurations or credential settings, disabling encryption keys or making the encryption keys inaccessible, etc.); (iii) that result from you not following the guidelines and best practices described in the Amazon Chime SDK Documentation on the AWS Site; (iv) that results from you not following the recommendations provided in an AWS Well-Architected Review; (v) that result from your equipment, software or other technology and/or third party equipment, software or other technology (other than third party equipment within our direct control); or (vi) arising from our suspension or termination of your right to use Amazon Chime SDK in accordance with the Agreement (collectively, the “Amazon Chime SDK SLA Exclusions”).

Additionally, to qualify for the SLA credit, you must have an Enterprise Support plan in place. A well-architected review is considered complete if all risks classified as “High” or greater have been addressed.

If availability is impacted by factors other than those used in our Monthly Uptime Percentage calculation, then we may issue a Service Credit considering such factors at our discretion.


  • “Availability” is calculated for each 5-minute interval as the percentage of Requests processed by Amazon Chime SDK that do not fail with Errors. If you did not make any Requests in a given 5-minute interval, that interval is assumed to be 100% available.
  • “Request” includes a SIP request to process an inbound or outbound SIP call, and an invocation of an Amazon Chime SDK API to create a WebRTC media session, attendees, media pipelines, or message channel, or to send or receive a message.
  • An “Error” is any Request that returns a 5XX error code or does not respond in response to a properly constructed SIP INVITE message as documented in the Amazon Chime SDK Documentation.
  • “Monthly Uptime Percentage” for the Amazon Chime SDK is calculated as the average of the Availability for all 5-minute intervals for a given AWS region in a monthly billing cycle. Monthly Uptime Percentage measurements exclude downtime resulting directly or indirectly from any Amazon Chime SDK SLA Exclusions.
  • A “Service Credit” is a dollar credit, calculated as set forth above, that we may credit back to an eligible account.
