Selling Partner API SDK

[pandjtrading]

The existing documentation still refers to using SwaggerGen and the api files found in this repository in order to build an SP-API SDK. However, the published nuget package found here: https://github.com/amzn/selling-partner-api-sdk seems to be regularly updated. It is available through nuget and is at version 1.1.0.
I have been continuously updating my own SDK since SP-API was available a few years ago. Should I be using this sdk for c# projects, as opposed to compiling my own sdk with SwaggerGen? what is the development team's advice on this?

Hi @pandjtrading,

Since 2025, official and pre-built SDKs are provided by the Selling Partner API for multiple languages. The currently released programming languages are: Java, JavaScript, C#, Python and PHP. The pre-built 1-click SDKs will be regularly updated and maintained by the Selling Partner API team.
The documentation will refer to both methods: the user-generated and pre-built SDKs.
Example:
Python for user-generated: https://developer-docs.amazon.com/sp-api/docs/tutorial-automate-your-sp-api-calls-using-python-sdk
Python pre-built: https://developer-docs.amazon.com/sp-api/docs/automate-your-sp-api-calls-using-a-prebuilt-python-sdk

The decision to use which depends on your specific system needs and level of integration. You can of course avoid re-compiling your SDK by using the pre-built ones to save time.

If you have any feedback or face any issues with pre-built SDKs, please contact us via this repo: https://github.com/amzn/selling-partner-api-sdk

Best,

Hi the namespace of the auth library also fixed in our latest release 1.1.2. Along with the actual fix for exception message. Please checkout Thanks !

It seems like there are quite a few 200 response error messages with the sdk package. I have just run into another one with settlement reports. last week I reported 2 separate issues with 200 responses throwing errors. These aren't new functions for our team; we have merely replaced the compiled sdk available here with the nuget package.
It appears as if the version number at 1.1.2 does not accurately reflect its current state. There is no discussion board on that project's repository, so I figured this place would be best to post a comment about it.
As it is, our team cannot trust the packaged SDK and will be rolling back to our compiled version.

I just installed 1.1.2 and the test code runs without throwing the exception. My initial parsing of the GetReportsResponse object from GetReports looked good. Thank you.

Hi Pandjtrading. Yeah please use our latest release 1.1.2 which should solve both the exception handling and the auth library namespace issue. And if there is still problem with that please let me know. Thanks

Hi just wanted to callout that https://www.nuget.org/packages/software.amzn.spapi/ now has official README page and a new release. For our documentation site content update is still in progress.
Thanks for calling out the issue and if there is more feedback just let us know.
