Integrating PayPal with Woocommerce (or any other platform) can be a real trouble. Especially with PayPal’s ever-changing interface. You never know where things are anymore. Here’s the step by step guide (with snapshots) to help you find the PayPal Identity Token for integrating with WordPress (or any other platform).
Step 1: Login to Your ‘PayPal Business Account‘

PayPal Personal Account

PayPal Business Account
Note: ‘PayPal Identity Token’ is available for ‘Business and Premier’ accounts only.
So if you have a personal account, you will need to upgrade your account to get a PayPal identity token.
Step 2: Click on Profile option at the top right of the page
Step 3: Click ‘Profile and Settings’
Step 4: Click the ‘Selling Tools’ tab
Step 5: Click on the ‘Update’ option in the ‘Website Preferences’ tab
Step 6: Select ‘On‘ for Auto Return & fill the Return url
Step7: Select ‘On‘ for Payment Data Transfer, Scroll to the bottom & click Save
Step 8: Copy the Identity Token (everything after the word “Website:” in the new window)
There you have your PayPal Identity Token
One question that a few of you might have is: Is it safe to share PayPal Identity Token with a developer?
Yes, Absolutely.
