How to generate a UPC-A barcode as a PNG file in Salesforce Apex

Barcodes are a crucial part of many businesses, but they can be quite difficult to generate, especially when using Apex. But don’t worry! I have just the thing for you: an API that can generate and read many types of barcodes. And to sweeten the deal even further, it works after just a few minutes of setup. Let’s get started.

First download this zip here and copy the client folder into your project.

https://github.com/Cloudmersive/Cloudmersive.APIClient.Apex.Barcode/archive/master.zip

Now we can call generateBarcodeUPCA:

SwagGenerateBarcodeApi api = new SwagGenerateBarcodeApi();
SwagClient client = api.getClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) client.getAuthentication('Apikey');
Apikey.setApiKey('YOUR API KEY');
Map<String, Object> params = new Map<String, Object>{
'value' => 'value_example'
};
try {
// cross your fingers
Blob result = api.generateBarcodeUPCA(params);
System.debug(result);
} catch (Swagger.ApiException e) {
// ...handle your exceptions
}

And look at that, we are already finished. Talk about a breeze.
