In this section, we are going to see how we should update our payment gateway keys for the application.
Since we are using 5 payment gateways, we should update our test & productions keys for server and flutter apps by the below admin app settings.
Go To Admin app Configurations menu & Click System settings & Click Installation settings, you can see the screen like below.
Note: For Paystack payment gateway you need to add an additional setup that is you should update call back url in paystack settings
Once you have updated the keys in the admin settings. you should update your callback url in paystack settings section like below.
Call back url example : "http://your-base-url/api/v1/payment/paystack/web-hook".
