Explicit field mapping

Payment gateway integration

Your first milestoneInspect the interfacesA useful review point before the next stage
Agree the source of truth
Safe retries and reconciliation
When two systems disagree, the integration needs a rule. We map fields, events and ownership before writing code so reconciliation is not an afterthought.
Documented operational ownership
Documented mappings and responsibilities make the connection easier to maintain.
In our clients’ words.
“ICM did a great job, on time and within specified budget.”
“If you need someone reliable and trustworthy, ICM Tech. are the people you want to hire for your needs.”
“Great Contractor! Simply WONDERFUL!”
WHAT YOU RECEIVE
Your Payment gateway integration project, clearly defined.
Businesses connecting ecommerce, finance, CRM, ERP, shipping or other operational tools.
Gateway connection
Agree the supported endpoints, authentication method, fields and trigger behavior. Test a normal run and representative failures, and document credentials ownership, usage limits and recovery without exposing secrets in logs.
Checkout integration
Connect the supported account and verify the important transaction states: success, pending, cancellation and failure. The scope identifies recurring provider charges and any refund or renewal behavior that needs separate configuration.
Payment-state validation
Connect the supported account and verify the important transaction states: success, pending, cancellation and failure. The scope identifies recurring provider charges and any refund or renewal behavior that needs separate configuration.
Scope and requirements
Merchant approval, currencies and card-data scope are controlled by the provider.
Any additional work is scoped and priced for your approval.
