Create, change, update, or delete authoritative DNS information on all Amazon Route 53 servers. Send a POST request to:

2013-04-01hostedzone/Amazon Route 53 hosted Zone ID /rrset resource.

The request body must include a document with a ChangeResourceRecordSetsRequest element. The request body contains a list of change items, known as a change batch. Change batches are considered transactional changes. When using the Amazon Route 53 API to change resource record sets, Amazon Route 53 either makes all or none of the changes in a change batch request. This ensures that Amazon Route 53 never partially implements the intended changes to the resource record sets in a hosted zone.

For example, a change batch request that deletes the CNAME record for www.example.com and creates an alias resource record set for www.example.com. Amazon Route 53 deletes the first resource record set and creates the second resource record set in a single operation. If either the DELETE or the CREATE action fails, then both changes (plus any other changes in the batch) fail, and the original CNAME record continues to exist.

Important: Due to the nature of transactional changes, you can't delete the same resource record set more than once in a single change batch. If you attempt to delete the same change batch more than once, Amazon Route 53 returns an InvalidChangeBatch error.

Use ChangeResourceRecordsSetsRequest to perform the following actions:

• CREATE : Creates a resource record set that has the specified values.
• DELETE : Deletes an existing resource record set that has the specified values.
• UPSERT : If a resource record set does not already exist, AWS creates it. If a resource set does exist, Amazon Route 53 updates it with the values in the request.

The values that you need to include in the request depend on the type of resource record set that you're creating, deleting, or updating:

Basic resource record sets (excluding alias, failover, geolocation, latency, and weighted resource record sets)

• Name

• Type

• TTL

Failover, geolocation, latency, or weighted resource record sets (excluding alias resource record sets)

• Name

• Type

• TTL

• SetIdentifier

Alias resource record sets (including failover alias, geolocation alias, latency alias, and weighted alias resource record sets)

• Name

• Type

• AliasTarget (includes DNSName , EvaluateTargetHealth , and HostedZoneId )
• SetIdentifier (for failover, geolocation, latency, and weighted resource record sets)

When you submit a ChangeResourceRecordSets request, Amazon Route 53 propagates your changes to all of the Amazon Route 53 authoritative DNS servers. While your changes are propagating, GetChange returns a status of PENDING . When propagation is complete, GetChange returns a status of INSYNC . Changes generally propagate to all Amazon Route 53 name servers in a few minutes. In rare circumstances, propagation can take up to 30 minutes. For more information, see GetChange
