Client API

generateProofs

A helper method to generate a state, nonce and codeVerifier which is used for validating the Identity response and protecting against cross site request forgery(CSRF) attacks

 {
  state: 'b6P4_eFMVTx_CFznmaHj9geXQUVm_z-xa8QgEmHEdNE',
  nonce: 'PVShAu4ZMyfPd6zV-GitTmu-yi3TFxPJhCjv8wjyweY',
  codeVerifier: 'Ek8FS-7c3AqTA-rPzF9c8-acO_-Mg4J3hpiKEzKllpc'
}

getAuthorizationUrl

Creates an authorization url with a signed JWT (using the private key in the JKWS). Since IDPartner implements the authorization code flow you should redirect to this URL.

| Parameter | Type | Description | | :--- | :--- | :--- | | query | string | Required. The query parameters that started the authorization flow after the end user clicks the IDPartner Button | proofs | object | Required. Use helper method generateProofs to generate a state, nonce and codeVerifier used for security & validations purposes | scope | array | string | Required. Specify the user attributes your require for your application IDPartner supports the standard OIDC scopes. For example - ["openid", "email", "address", "offline_access"] | extraAuthorizationParams | object | Optional. Send extra authorization params that should be sent to the OP. | extraAuthorizationParams.prompt | string | Optional. Set it to consent if you need a refresh token returned by the OP | extraAuthorizationParams.claims | object | Optional. Set it to ask for specific claims. Use it as a way to augment/limit the claims returned by scope param. More info in https://openid.net/specs/openid-connect-core-1_0.html#ClaimsParameter.
