Where this service fits
An integration should remove duplicate work without making the process harder to understand. We identify the systems involved, which one owns each record and when information needs to move. A payment event, inventory update or customer request can trigger several steps, and each needs a clear result that the application and operating team can inspect.
We design and implement the agreed API endpoints, webhooks or scheduled exchanges with validation and access controls. Error handling is planned alongside the successful path. That can include retries, duplicate-event protection and a way for staff to resolve records that need attention. The interface should communicate the status of the work instead of leaving people to guess whether a request completed.
THE WORK IN PRACTICE
Connections with a clear role in the business.
Tech Micro USA
Tech Micro USA connects B2B commerce with carrier services, Authorize.net and QuickBooks. The case study follows product discovery, orders, shipping and financial operations, showing how distinct systems support one order lifecycle.
Read the Tech Micro USA case studyWhat the work can include
We agree the deliverables around your product and existing setup. A focused engagement can include the following work.
- System mapping and field-level data contracts
- API endpoints, webhooks or scheduled synchronisation
- Authentication, validation and permission boundaries
- Error handling, operational visibility and integration documentation
Planning your project
Useful inputs include API documentation, sandbox access, example records and the business rules for conflicts or missing information. Provider limits, data volume and existing technical constraints can affect delivery. We agree how credentials are managed and who responds when an external service changes its behaviour.
The estimate should identify the work, assumptions and responsibilities on both sides. We can shape a first phase around the highest-priority outcome, with additional work planned separately once the relevant decisions have been made.
Share your starting pointAgree what each system owns
An API integration starts with a contract for the data and the work. Name the event that starts the process, the record identifiers, required fields and the system responsible for each value. Decide what happens when a customer changes an address, a record is missing or two systems disagree. Those decisions prevent an integration from becoming an unexplained copy of data in several places.
We can implement endpoints, webhooks, scheduled exchanges and operational tools around the APIs available to your accounts. Payment, shipping, identity, accounting and CRM services have different permissions and limits. Tech Micro USA is a relevant example of connecting carrier, payment and accounting functions to the order journey. Your scope is agreed against your own providers and the workflows they support.
Design recovery before relying on automation
A successful request is only one part of an integration. Events can arrive late, be repeated or stop after an external service accepts a change but before your application records the result. We define duplicate-event handling, processing states and a reconciliation path for the actions in scope. Retrying an operation should account for whether it could create a second payment, shipment or other business record.
Depending on the task, recovery can use queued work, a retry with a defined limit, a status screen or a staff review. Logs should help identify the affected record without unnecessarily exposing sensitive data. We agree who is notified, what they can correct and how the process returns to a consistent state after an interruption.
Verify permissions, delivery and handover
Credentials and provider access are reviewed before implementation. We plan environment separation, appropriate permissions, input validation and the verification required for incoming events. A backend checks whether an action is permitted; the interface communicates its outcome. Specific compliance or retention requirements need to be included in the brief so the implementation and any specialist review can be scoped.
Acceptance checks should use representative records and provider sandboxes where available. We exercise successful requests, rejected data, unavailable services and duplicate or delayed events relevant to the workflow. Handover identifies endpoints, configuration, account owners, recovery instructions and the person responsible for provider changes. Ongoing operation and vendor fees are visible in the proposal.
How delivery works
Understand the work
We start with your users, business model and current constraints. Bring an idea, a running product or a workflow that causes friction. Together we identify what needs to change and what a useful first outcome looks like.
Shape a practical scope
We connect the user journey to the design, engineering and operational work it needs. Assumptions, dependencies and responsibilities are discussed early, so you can make informed decisions about the first release and the work that follows.
Build with visible progress
Designs, prototypes and working features give us something concrete to discuss. We review progress with you, resolve questions as they arise and test the important journeys. Changes to priorities are considered against the agreed scope.
Launch and keep improving
Release preparation includes the agreed testing, deployment and handover. We make support responsibilities clear and can continue as your product team, improving the experience as you learn from real use and plan the next release.
Prepare the decisions behind your project.
Work through the billing, webhook and recovery decisions that shape an integration.
Keep subscription access consistent
Connect provider events to product access with defined billing states and recovery.

Read the guideFrequently asked questions
What happens if a third-party service is unavailable?
The required behaviour depends on the task. We may queue work, show a recoverable error or allow a person to retry an operation. We define that behaviour during scoping and test representative failures as well as successful requests.
Can you connect our existing tools without rebuilding the product?
Often, when the required APIs, events and account permissions are available. We review the current application and data flow first. A focused integration or operational screen may be enough; the proposal identifies any application changes that the connection actually needs.
How do you handle duplicate webhook events?
We define how an event is identified, recorded and processed, and how an already completed action is recognized. The design also needs a path for uncertain outcomes, such as a vendor accepting a change before your system records completion. We test the workflow’s recovery behaviour rather than assuming every retry is safe.
Can you integrate payment, shipping and accounting services?
Yes, subject to the APIs and account access available for your chosen providers. Tech Micro USA’s documented scope includes carrier services, Authorize.net and QuickBooks. A new engagement confirms the records, permissions, sandbox setup and business rules for each connection.
What happens when an external API changes?
We document the dependency, versioning constraints and the owner of monitoring and maintenance. Provider changes may require updated credentials, configuration or code. The support arrangement should state how those changes are reviewed, tested and released, including any response expectations.
What do you need before starting integration work?
Bring provider documentation, account permissions, sandbox access where available and examples of the records or events involved. Explain the required result and what your team does when the current process fails. Avoid sending secrets through an inquiry form; we arrange the necessary access during the agreed onboarding.
Can this be a focused engagement within our existing product?
Yes. We can scope this work around an existing product after reviewing the relevant design, code or operating setup. We identify the dependencies and agree what is included, who provides access and how the change will be reviewed. If another part of the product also needs work, we explain that before expanding the scope.
