Let me start my steps to integrate PayPal payment gateway using PHP web development language.

Step 1 : Setup PayPal main account.

First of all, you need a main account of PayPal to test PayPal payment gateway using php web development language. so just go to and create a account (Personal account). Just create a account using your personal details. You not need to enter bank, PAN etc details. It will be use to create sandbox seller and buyer accounts. For example, i have created this is my main PayPal account email id. Have you done, Let go to step 2.

Now we will create two test account one for seller and second one for buyer.

What is sandbox : Sandbox is the testing environment of PayPal. It words as real account but it is only for testing. All the balance, transaction etc will be for testing.

Let we create two PayPal sandbox account to make payment using these two seller and buyer account.

Select Business (merchant account) if this is seller account.

Select Personal (buyer account) if this is buyer account.

You need to create both account so first create a Business (merchant account) account and then Personal (buyer account) account.
