Implementations

impl Auths

pub async fn post_token(&self) -> Result<Response<OAuth2Token>, ClientError>

Get OAuth2 token.

This function performs a POST to the /token endpoint.

Returns an access token for accessing endpoints. There are three methods to get an access token:

• “authorization_code”: Authorization Code Grant method, used for retrieving an access token for the first time
• “refresh_token”: Refresh Token method, used for retrieving subsequent access tokens using the refresh token provided from authorization code grant
• “client_credentials”: Client Credentials method, allows direct retrieval of access tokens with only client id and secret.

There are two main flows: Authorization Code Grant + Refresh Token; or Client Credentials.

For Authorization Code Grant + Refresh Token, the flow would be as follows:

• Follow authorization process to get an authorization code
• Use authorization code to retrieve an access token and refresh token from this endpoint
• Use refresh token to retrieve new access tokens from this endpoint (without having to go through authorization process again)

For Client Credentials:

• Call token endpoint with client credentials to retrieve access token

The request body is different for the methods:

• grant_type = “authorization_code”
  • code
  • redirect_uri
• grant_type = “refresh_token”
  • refresh_token
• grant_type = “client_credentials”
  • no additional data

Some important notes:

• Unlike other endpoints, the data format must be “application/x-www-form-urlencoded”, according to RFC specifications
• To use a particular code grant, it must be included in the “Grant Types” section of the App Settings modal in app.ramp.com
• Only the authorization code grant returns a refresh token
  • Additionally, the “Refresh Token” grant type must be selected in App Settings for the refresh token to be returned
• The token endpoint used to be “/public/v1/customer/token” - this endpoint is now deprecated and should not be used

Parameters:

• authorization: &str – Basic <base64-encoded client_id:client_secret>.
