In our application we allow users to navigate to + select a Data Extension (including in a folder) and then we read the column names from it to help them map their data. This was originally implemented through the Soap API. As we have other functions which related to classic email we used to use that, we've since migrated the email functions to use Content Builder. More recently still we updated to use the new style of authentication tokens + endpoints.
So I had been able to access Data Extensions through the Soap api in the past, but with recent changes to the authentication endpoints this is no longer possible. My options are to
- Update my authentication code to use new style credentials with the SOAP api
- Update my code to use the REST API to access data extensions
I've had a quick look at the developer docs and it's not immediately clear if either of these approaches are possible. Does anyone know if data extensions are accessible through the REST api (this is preferable to having a mixture of REST and soap calls, and I'm using REST for Content Builder). Otherwise can I use the new authentication endpoints with SOAP?
