Copy the API keys into project manager. Press Save Changes when done. But do not close the API page yet.

Filling in the redirect URI is important. Users will be redirected upon successful (sometimes unsuccessful) payment to this site. Though this is optional but its better to have a page that confirms the user if the operation was completed or not.

Also a cool thing about stripe is that you can use your localhost address here, works totally fine.


Now you can test it if it is working. Ticking the “Enable Stripe test secret key” and you will be able to test the functions in Demo. Stripe itself provides you with a test application and API keys for your convenience. But the demo mode allows you to turn them on or off if you have them filled in.

Create a new project or go to an existing project, go to the invoice tab and generate your invoice using stripe connect.


Tick off the Test keys which you turned on previously to use it live. You are done!
