Visual Studio Code (or just VSCode) is a free source code editor developed and maintained by Microsoft. The REST Client plugin requires just a plain text file with the extension .http or .rest.

1. Open Visual Studio Code
2. Create a file with name api.http Or you can give any name but file extension should be .http Or .rest.
3. Copy the below code to the file

###
@hostname = <your-company-base_URI>
@your-client_id = <your-client_id>
@your-client_secret = <your-client_secret>
@username = <your-company_uuid>
@password = <your-company_request_token>

Replace the placeholder as per your application configuration your-client_id, your-client_secret, your-company_uuid and your-company_request_token you have generated in previous step.

When making the call, you will use your app’s geolocation as the base URI followed by the endpoint. For example, if your geolocation is https://us.api.concursolutions.com, you will call https://us.api.concursolutions.com/oauth2/v0/token.

The first time you request for a refreshToken This is used to get a new accessToken when one has expired.

1. Copy below code just below the above code to Obtain a refresh token and store it to a variable.

### Obtain a Refresh token
# @name refeshTokenCall
POST {{hostname}}/oauth2/v0/token HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Connection: close
Content-Length: 175

client_id={{your-client_id}}
&client_secret={{your-client_secret}}
&grant_type=password
&username={{username}}
&password={{password}}
&credtype= authtoken

###
@refeshToken = {{refeshTokenCall.response.body.refresh_token}}

The Oauth2 service generates access tokens for authenticated applications. The token returned in the Oauth2 response can be used to access protected resources on SAP Concur services.

1. Copy below code just below the above code to Obtain a access Token and store it to a variable.

### Obtain an Access Token
# @name accessTokenCall
POST {{hostname}}/oauth2/v0/token HTTP/1.1
Content-Type: application/x-www-form-urlencoded
Connection: close
Content-Length: 167

client_id={{your-client_id}}
&client_secret={{your-client_secret}}
&grant_type=refresh_token
&refresh_token={{refeshToken}}

###
@accessToken = {{accessTokenCall.response.body.access_token}}

The base URI for all subsequent calls. Armed with the accessToken you can start making calls to an SAP Concur API. Here’s an example How you can retrieve Expense Report by utilizing the appropriate base URI with the access token.

### Get Expense Report
# @name getExpenseReport
GET {{hostname}}/api/v3.0/expense/reports?limit=100&user=ALL HTTP/1.1
Authorization: Bearer {{accessToken}}

Using VS Code extension you can make these API calls easily by giving the references to the required response objects in the first call and using them in the next call.
