When using the SDK you have two options.

  • Have users login to Yoco from within your application (this is usually the easiest approach if you will have lots of businesses using your integration)
  • Have your application pass in a pre-configured API token for each business. You will need to co-ordinate with Yoco to create a token for each business that will use your integration.

Approach 1: To allow your user to login to Yoco from within your app

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// ...your other code
// Configure the YocoClient with your integrator secret (this identifies your software)
[YocoClient initWithSecret:@"your-yoco-integration-secret"];
// ...more code
return YES;

As soon as the business initiates their first Yoco transaction they will be shown a login dialog. If you would like to control when they are shown this dialog, you can force the login process by using the following:

[YocoClient login:self success:^{
NSLog(@"Yoco logged in!");
} cancel:^{
NSLog(@"User cancelled without logging in successfully");

Approach 2: To use a pre-negotiated API token

[YocoClient initWithSecret:@"your-yoco-integration-secret" andApiToken:@"your-api-token"];
