Dynamic variable with Json_Exporter

[rs]

Hi all,

I want to run a series of REST calls to monitor an endpoint. The issue is that the final endpoint requires using a dynamic variable in the REST path that can change. 

Here's the scenario:

1. The first rest call would require using Json_Exporter to parse an integration_key field and save that variable. This can consist of multiple integration_key's

2. The 2nd REST call would be to use that integration key in the rest call: 

GET https://application/api/1/${integration_key}/status

Or in prometheus.yml, have something like this:

```

scrape_configs:
- job_name: json_exporter
...
   - targets: 

      - https://application/api/1/${integration_key}/status

```

Is something like this possible?
