Using OpenSea API to get collections

Hey guys -

I want to use OpenSea’s API to get the data for all collections and throw them into a repeating group. I’m new to APIs so I don’t really know what I’m doing, and even though the call is initializing, I’m not seeing the data in the RG.

Here’s what the call looks like…

The call initializes just fine. But here’s what the repeating group looks like.

The zeros you’re seeing in the repeating group are the total volume for that collection. No matter how I sort it, every single row (collection) has a volume of zero and obviously that’s not true.

Any ideas on how to fix this?

Thanks! Still new to APIs.
