This article explains how to find out the id of a Datasource in Grafana when you know its name.

The article is based on the following documentation: https://grafana.com/docs/grafana/latest/developers/http_api/data_source/#get-a-single-data-source-by-name

Use the following script to reach Grafana API by IP with username and password.
Note: values in this script are only an example. Before running this script on your machine, first update grafana_host, grafana_port, grafana_username, grafana_password, and datasource_name with your own actual values.

#!/bin/bash

#Get a single data source by name
#GET /api/datasources/name/:name

grafana_host=10.2.7.100
grafana_port=80
grafana_username='admin'
grafana_password='adminz-password'
datasource_name='hivemq-prometheus-1'

curl --location \
  --header 'Content-Type: application/json' \
  --header 'Accept: application/json' \
  "http://${grafana_username}:${grafana_password}@${grafana_host}:${grafana_port}/api/datasources/name/${datasource_name}"

Use the id value as Datasource id.

If all credentials are valid, the output of the script is JSON like this:

{
  "id": 11,
  "uid": "abcd1efgh",
  "orgId": 1,
  "name": "hivemq-prometheus-1",
  "type": "prometheus",
  "typeName": "Prometheus",
  "typeLogoUrl": "public/app/plugins/datasource/prometheus/img/prometheus_logo.svg",
  "access": "proxy",
  "url": "http://prometheus-kube-prometheus-prometheus:9090/",
  "password": "",
  "user": "",
  "database": "",
  "basicAuth": false,
  "isDefault": true,
  "jsonData": {},
  "readOnly": true
}

If the Grafana IP is incorrect you will get an error like this:

curl: (7) Failed to connect to 10.2.7.100 port 80 after 6058 ms: Couldn't connect to server

If user credentials are invalid you will get an error like this:
```
{
  "message": "invalid username or password"
}
```
If the request is not authorized you will get an error like this:
```
{
  "message": "Unauthorized"
}
```
