Step-by-step guide for integrating OCBC (or any) payment gateway into PlagSini EV.
Get Credentials from OCBC
After your proposal is approved, OCBC will provide:
• Merchant ID — Your unique merchant identifier
• API Key — For authenticating API requests
• API Secret — For signing/verifying requests
• Sandbox URL — Test environment endpoint
• Production URL — Live environment endpoint
Key-In Credentials Here
Click "+ Add Gateway" → Select "OCBC" → Fill in the credentials from step 1. Start with Sandbox mode for testing.
Give OCBC Your Callback URL
OCBC needs to know where to send payment confirmations. Give them this URL:
Open User Top-Up page — customers login and pay via TNG QR
This endpoint receives payment confirmations automatically.
Test in Sandbox
Make test payments using OCBC's sandbox credentials. Check the Transactions tab to verify everything works.
Go Live
Once testing is done:
1. Update credentials with Production keys from OCBC
2. Toggle Sandbox OFF
3. Set as Default gateway
4. Enable the gateway → Done! 🎉
