Is Oauth needed for API v3 usage?

We have an integration that uses the older API’s.  For example I just make a cURL request to

https://a.klaviyo.com/api/v1/lists?api_key=xyz

Will I still be able to do this by passing the api_key with v3 endpoints or do I need to authenticate first with oauth now?  

And if so can I just convert to the lack of a v# like the docs say is not used anymore?  
For example: https://a.klaviyo.com/api/lists?api_key=xyz ?  is that all that is needed?

Hi @kenw232!

My apologies for the delay here - oAuth is not required to make a V3 API call. To answer your second question - yes, as long as you include your api key in the header, the new V3 APIs do not require the ‘V3’ identifier. It’s also recommended to use our dynamic documentation to build your request so that it’s formatted correctly.

 

Thanks for using the Community!
