Has anyone else received an error when attempting to connect to Amazon SES service?  I have verified the credentials and even used them on Integromat to successfully connect.  Zapier, on the other hand, gives me this error: 

 

authentication failed: An error occurred (SignatureDoesNotMatch) when calling the ListVerifiedEmailAddresses operation: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

Hi @jrcmatthews 

Check out this help article for Amazon SES: https://zapier.com/help/doc/how-get-started-amazon-ses

Hi @Troy Tessalone , Thanks for the assist but (generally speaking) this is exactly what I’ve tried.  The Zapier screen doesn’t really match 100% what is in those docs but the parts that do I’ve tried as instructed.

Still no joy...(what Zapier really prompts when attempting to add Amazon SES connection)

@Troy Tessalone , yes, I’ve done that.  I was hoping someone in the community had a quick answer but I’ll chase it with them.  Thanks!

Here is the response I rec’d from Zapier support on the Amazon SES “issue” I had.  Great reply and their recommendation worked perfectly!

--- Start

I found the following article in Amazon forums (for AWS from awhile back) for the error
 An error occurred (SignatureDoesNotMatch) when calling the ListVerifiedEmailAddresses operation: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method.
 
The article is given here: https://forums.aws.amazon.com/thread.jspa?threadID=88463
 
In this case, the users who were running into this error were using the credentials generated when creating the SMTP user and use the global access keys (AWS Access Key ID and AWS Secret Access Key).
 
The following article outlines how to retrieve your AWS access keys: https://docs.aws.amazon.com/ses/latest/DeveloperGuide/get-aws-keys.html

-- End

The confusion was between the credentials for the SMTP user versus the AWS keys.

 

Thanks and I hope this helps others!
