Hi,

We use to work fine with dwolla sandbox environment where we got identifiers with URL like “[https://api-uat.dwolla.com](https://api-uat.dwolla.com)…”. Today when I tests a new feature with webhook, I receive a event with identifier urls all starting with “[https://api-sandbox.dwolla.com](https://api-sandbox.dwolla.com)…”, which couldn’t retrieve any object from dwolla:

{“code”:“NotFound”,“message”:“The requested resource was not found.”}

But If I change it back to “api-uat…”, then it can find the correct resources.

I am wondering what’s going on with the sandbox webhook?

Hi @Rongjian_Lan, Can you update to the latest version of whatever SDK you’re using to see if that resolves the issue for you?
