If you have developed your website “from scratch” or are integrating Pesapal into any other e-commerce, banking or billing systems, you can access Pesapal API documentation and integrate directly.
This information is available on the email address that was used to open your business account. In case this does not come through, log into your Pesapal business account and resend the API credentials.
When integrating Pesapal, a developer can test it on http://demo.pesapal.com before going live on Pesapal’s Sandbox. The developer can create test merchant and buyer accounts, post transactions, make payments using Pesapal’s mobile money test module, query for payment status and more. No real money is used here hence no real transactions are done.
