Hello,
I would like to monitor an API call from ES and Kibana. The HTTP module in MetricBeat seems like the most logical choice. I have installed it, and I see that it is writing to ES. However, I am having issues configuring it. So far, I have this:
- module: http
metricsets:
- json
period: 10s
hosts: ["https://"]
namespace: "json\_namespace"
path: "/"
#path: "/"
ssl.verification\_mode: none
#body: ""
method: "GET"
#username: "user"
#password: "secret"
request.enabled: true
response.enabled: true
#json.is\_array: false
#dedot.enabled: false
However, I keep getting, in Kibana, the following error:
"Authorization has been denied for this request"
I have tried adding the header for the API\_KEY and its value, but no luck. I confirm that from the ES server, the curl command with the API\_KEY and its value added as a header returns the query results. Would any know how I can add the header? I tried
header: "API\_KEY:"
headers: "API\_KEY:"
and a bunch of variations... It seems to simply ignore the information. nay help would be greatly appreciated.

A note for the entry above: not all of the values were accepted, so let me try the confirguation again:
module: http
metricsets:
- json
period: 10s
hosts: ["[https://valueofserviceURL](https://valueofserviceURL)"]
namespace: "json\_namespace"
path: "/pathofAPI"
#path: "/"
ssl.verification\_mode: none
#body: ""
method: "GET"
#username: "user"
#password: "secret"
request.enabled: true
response.enabled: true
#json.is\_array: false
#dedot.enabled: false
I tried adding:
header: "API\_KEY:value"
headers: "API\_KEY:value"

Hi @RunningSmurf 🙂
I'd say that your headers format is not correct, check here [https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-ssl.html](https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-ssl.html)
It should be
```auto
headers:
API_KEY: "value"
```
Best regards!

Thank you, this worked!
