How to delete a DNS record in Route 53? I followed the documentation but I still can't make it work. I don't know if I'm missing something here.

Based on the documentation:

DELETE : Deletes a existing resource record set that has the specifiedvalues for Name , Type , SetIdentifier (for latency, weighted,geolocation, and failover resource record sets), and TTL (except aliasresource record sets, for which the TTL is determined by the AWSresource that you're routing DNS queries to).

But I'm always getting this error:

Traceback (most recent call last):                                                                                                                                      File "./test.py", line 37, in <module>                                                                                                                                main()                                                                                                                                                              File "./test.py", line 34, in main                                                                                                                                    print(del_record())                                                                                                                                                 File "./test.py", line 23, in del_record                                                                                                                              'TTL': 300                                                                                                                                                          File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/botocore/client.py", line 251, in _api_call                                       return self._make_api_call(operation_name, kwargs)                                                                                                                  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/botocore/client.py", line 537, in _make_api_call                                  raise ClientError(parsed_response, operation_name)                                                                                                                  
botocore.exceptions.ClientError: An error occurred (InvalidInput) when calling the ChangeResourceRecordSets operation: Invalid request 

Here's my code:

#!/usr/bin/env python3import boto3r53 = boto3.client('route53')
zone_id = 'ABCDEFGHIJKLMNO'
record = 'me.domain.com'
r_type = 'CNAME'
r_val = 'google.com'def del_record():response = r53.change_resource_record_sets(HostedZoneId=zone_id,ChangeBatch={'Changes': [{'Action': 'DELETE','ResourceRecordSet': {'Name': record,'Type': r_type,'TTL': 300}}]})return responsedef main():print(del_record())if __name__ == '__main__':main()

You need a nested 'ResourceRecords' array in the ResourceRecordSet, which has the current 'target' value of the record.

    HostedZoneId=zone_id,ChangeBatch={'Changes': [{'Action': 'DELETE','ResourceRecordSet': {'Name': record,'Type': r_type,'TTL': 300,'ResourceRecords': [{'Value': target}]}}]}
