Production access

Production credentials are generated by you, in the London Bridge internet banking. They are released only after the commercial and technical gates below are cleared.

London Bridge never sends you credentials

Nobody at LB Pay will e-mail you a client_secret. You generate it yourself in the internet banking, and it is shown to you once. If you ever receive credentials from someone claiming to be LB Pay, treat it as fraud and report it.

The process

Three gates clear first — none of them technical on your side. Then the six steps are yours.

#	Step	What it means
1	KYB approved	Your company passed Know Your Business verification
2	Contract signed	Commercial terms closed
3	Integration checklist validated	Every item in the certification checklist reviewed and accepted
4	Access arrives by e-mail	The invitation goes to the contact registered during onboarding
5	Create your internet banking user	Complete the registration from the invitation link
6	Generate your credentials	Open the Integrations tab and create the client_id and client_secret. Copy the secret immediately — it is shown once. Store it in a secrets manager, never in source control
7	Generate the production mTLS certificate	Certificates are environment-specific: PROD is a different one from SDB. Follow mTLS Onboarding again, and remember the private key never leaves your infrastructure
8	Send your source IPs	Production only accepts calls from addresses you declared. Include every egress IP — NAT gateways and secondary regions included — or the ones you forget will be refused
9	Run test transactions in production	Small, real amounts. Confirm a deposit and a withdrawal end to end, verify the webhooks arrive, and reconcile both against GET /v1/statement
10	Scheduled go-live	Agree a date and time with London Bridge for an accompanied go-live. Someone from LB Pay follows the first production traffic with you, so a problem is caught while both sides are watching
