First of initiate the client with stateful oauth credentials. E.g., in init
func init() {
salesforceclient.Initiate(salesforceclient.Config{
ClientID: "<your client id>",
ClientSecret: "<your client secret>",
RedirectUrl: "<guess what: redirect url>",
Scopes: []string{"api", "chatter_api"},
})
}After the grant & token exchange (it's pretty straight forward), create a client and... use it.
sf, _ := salesforceclient.CreateInstance(ctx, token)
_ = sf.CreateCase(request)
