Create access tokens

Having an existing and active user account to access the GPM Plus or GPM SCADA environment.
Having the client {host} and {port}, where {host} is your company host name and {port} is the port you use to connect to the system. The host and port can be found in the URL: www.http://{host}.greenpowermonitor.com:{port}.

To create an access token, or bearer token, follow these steps:

Note: You need the client {host} and {port}, which can be found in the URL: www.http://{host}.greenpowermonitor.com:{port}.

Note: The token expires 24 hours after either its creation or its last use. If the

GPM Web API

calls returns a 401 error, indicating an expired token, you will have to create a new token. However, if the token is used within the 24-hour timeframe, it will be automatically refreshed, and this cycle continues every subsequent 24 hours with each usage.

Access the Client Swagger using one of the following links:
- WebAPI: https://webapi{host}.horizon.greenpowermonitor.com/swagger/ui/index/#
- SCADA: http://{host}.greenpowermonitor.com:{port}/swagger/ui/index#/
  Note: {host} is your company host name and {port} is the port you use to connect to the system.
Go to the Account section and find the token endpoint.
```
POST /api/Account/Token
```
Enter your credentials on login and then click Try it out.
```
{
  "username": "{your_username}",
  "password": "{your_password}"
}
```
Note: You need
valid and active credentials for GPM Plus or GPM SCADA.
If the request is successful, you will get a "200 HTTP" Status Code and a response body containing the access token and its expiration time.
```
{
  "UserName": "{your_username}",
  "AccessToken": "{bearer_token}",
  "TokenType": "bearer",
  "ExpiresIn": "Minutes : xxxx.xxxxxxxxxxxx"
}
```

You have the access token. You must include it in all your GPM Web API calls.
