### Virtual Method

# EDataServer OAuth2Serviceprepare_get_token_form

since: 3.28

#### Declaration [src]

    void
    prepare_get_token_form (
      EOAuth2Service* service,
      ESource* source,
      const gchar* authorization_code,
      GHashTable* form
    )

#### Description [src]

Sets additional form parameters to be used in the POST request when requesting access token after successfully obtained authorization code. The default implementation sets some values too, namely “code”, “client_id”, “client_secret”, “redirect_uri” and “grant_type”. These parameters are always provided, even when the interface implementer overrides this method.

The `form` hash table expects both key and value to be newly allocated strings, which will be freed together with the hash table or when the key is replaced.
