Amazon API update

Submitted by richard on Wed, 2020-01-22 23:05 in

Hi David,

I have just received an email from Amazon stating:

We would like to inform you that all of your applications making calls to Amazon’s Product Advertising API version 4.0 (PA API 4.0) will need to upgrade to Amazon’s Product Advertising API version 5.0 (PA API 5.0) by March 9, 2020.

Is there anything we need to do within PT for either wordpress or stand alone installations?

Best regards,

Hi Richard,

I'm going to look into this next week - my plan is to make a proxy script that makes the V5 request and returns V4 format XML that can be passed into the existing code without modification. I'll update once available...

Hi David,

We have the updated amazon.php for standalone installs, is there a new version for pto_api_amazon.php ?

Hi Graham,

Sure - please could you email me the api/pto_api_amazon.php you currently have (It's easiest this way as I have helped users with many modifications over the years!) and I'll convert for version 5 for you...
