Get value from Rest

Hi to all

I’m using the server connect to get values from Rest server, and I get this values json :

{“api_credentials”:{“status”:200,“headers”:{“content-type”:“application/json; charset=utf-8”,“content-length”:“242”,“date”:“Thu, 17 Jun 2021 14:01:18 GMT”,“server”:“Python/3.6 aiohttp/3.6.3”,“connection”:“close”},“data”:{“referent”:“057dbfe4-8dcb-407f-a67f-dd9ae424af41”,“attrs”:{“id”:“123456789”,“rg”:“123456789654123”,},“schema_id”:“NDC1NBuWaTcNRn3MkxMUtm:2:identidade:1.0”,“cred_def_id”:“NDC1NBuWaTcNRn3MkxMUtm:3:CL:20:default”,“rev_reg_id”:null,“cred_rev_id”:null}}}

How I get the all values from “attrs”, I’m trying to use “Repeat” but I’m not getting ?
