Your data stays trustworthy
One agreed source of truth per field means two systems cannot both be right and disagree.
Connect catalogue and order systems with explicit data ownership.
We build supported connections between the storefront and inventory, fulfilment, CRM or other agreed systems. Field mapping and record ownership are defined before synchronisation so updates do not overwrite the wrong source.

What we do
API integration for ecommerce businesses: data contract, connection build, end-to-end checks.
What API integration needs to account for.
Two systems editing the same stock field can create conflicting values.
An accepted request does not prove the destination completed the intended action.
Retry behaviour must not duplicate orders or shipments.
What happens after the successful test.
Most integrations work on the first submission. The cost shows up months later, in duplicate records, silent failures and data nobody trusts.
Failures are visible
Validation, duplicates, retries and failure behaviour are defined, so a broken connection announces itself instead of losing enquiries.
Manual re-entry disappears
Work somebody is currently copying between two tools becomes a trigger, and that person gets the hours back.
API integration scope.
Plan data contract, connection build and end-to-end checks as connected parts of the engagement.
Data contract
Verify product identifiers, order fields and provider endpoints. Define which system owns price, stock and customer information.
Connection build
Implement validation, authentication and event handling. Account for rate limits, duplicate notifications and unavailable providers.
End-to-end checks
Verify resulting records using authorised test scenarios. Document reconciliation, logs and the process for retrying failures.

“What I appreciate most is that the team always communicates openly and stays honest throughout.”
“They delivered what they said they would, on time.”
“They met all our expectations by providing great strategies based on our needs.”

Our process
How we approach API integration.
Agree catalogue and order contracts
Verify identifiers, field ownership and supported endpoints in each connected system.
[ 01 ]
Implement validated events
Build the connection with authentication, rate-limit handling and safe treatment of repeated notifications.
[ 02 ]
Verify destination records
Use authorised scenarios to check actual data changes and document reconciliation and recovery.

Let's chat
“I've spent 10 years working across development and marketing. I started as a developer, but design, SEO and advertising were already part of the job. That taught me to treat a website as one system: the business, the content, the design and the code have to work together. At Norml, I lead the architecture behind our work and stay involved wherever strategy, design, development and search meet.”

Get startedAPI integration for ecommerce businesses: questions.
Can you sync products across more than one channel?
Yes, when ownership, identifiers and each provider’s supported behaviour are defined. Conflicts need an explicit resolution rule.
Will customer data appear in browser requests?
Only the information required and authorised for that interface should be exposed. Private credentials and sensitive records need appropriate server-side handling.
