Systems that talk to each other without losing a record.
We build the connections between your website, store, CRM, payment tools and internal software: API clients, webhook receivers and sync jobs that survive slow responses, duplicate messages and changed fields. The work is done from Lahore for teams in many countries.
How should two business systems exchange data safely?
Agree on one source of truth for each record, then define a data contract: fields, formats, authentication, timezone and what deletion means. Send changes by webhook or queue instead of live coupling, give every write an idempotency key so a repeated message does nothing new, and keep logs that let someone compare both sides. Plan for the other system being slow or offline, because it will be, and decide in advance who fixes the records that fail.
Webhook senders usually retry on failure, so receivers should expect the same event more than once. Stripe documents this in its webhooks guide.
The kinds of systems we link every month.
Most requests fall into a small number of patterns. Naming the pattern early makes the scope, risk and cost easier to see.
Store and fulfilment
Orders from WooCommerce or Shopify flow to shipping carriers, warehouse tools and accounting software, and stock levels flow back.
Website and CRM
Form leads, quote requests and account sign-ups reach the CRM with the right owner, source and fields, without anyone retyping them.
Payments and invoicing
Payment gateway events create invoices, mark orders paid and open refund records, with every amount matched to one order.
ERP and internal tools
Product, customer and price data moves between an ERP and the public site on a schedule that the business agrees to.
Marketing platforms
Email tools, ad platforms and analytics receive consent-aware customer events so segments stay current.
Public and partner APIs
Data from supplier feeds, job boards or regulators is fetched, cleaned and published, with limits and terms respected.
Four decisions made before any code.
Integrations fail at the edges, not in the happy path. We write the edges down first, in a short contract both teams can read.
What the contract fixes
- Identity. Which system owns each record, which external ID is stable, and how existing records are matched so nothing is created twice.
- Shape. Field names, types, required values, timezone, currency and the meaning of a delete, with a version number so changes can be introduced safely.
- Delivery. Whether data moves by webhook, polling or queue, how often, and what happens when limits or timeouts are hit.
- Reconciliation. How mismatches are found, who owns them, and how a record is replayed once it has been fixed.
Writing this down also exposes the awkward questions early, such as who wins when both systems edit the same customer.
From first call to monitored release.
Each integration moves through the same six stages. You see working results at a test stage before anything touches live data.
- 01
Scope the flow
We list the trigger, the data, the systems on both sides and the people who depend on the result.
- 02
Read the API
Documentation, rate limits, sandbox access and authentication methods are reviewed before a design is promised.
- 03
Design and mock
The contract is drafted and tested against sample payloads, including bad ones.
- 04
Build with safeguards
Code is written with retries, idempotency keys, validation and clear error messages from the start.
- 05
Test on a sandbox
Realistic data runs through both systems, including duplicates, timeouts and malformed input.
- 06
Release and watch
Go-live is staged, logs and alerts are switched on, and the first days are monitored closely.
Four habits that make integrations fragile.
Many of our projects begin as a repair. These patterns appear again and again in integrations built in a hurry.
Trusting the happy path
Code is tested with one clean sample and fails the first time a field is empty, a name contains an accent or a price has three decimals.
Syncing without an owner
Two systems both edit the same customer and nobody has decided which one wins, so changes overwrite each other without a trace.
Hard-coded keys and URLs
Credentials sit in plugin settings or workflow fields, and a test endpoint is still being used months after launch.
No view of what failed
Errors are swallowed quietly, so the team finds out weeks later when a customer asks where an order went.
Receiving a message the right way.
A webhook looks simple: a system sends your server a notice. In production there are several ways it goes wrong, and each has a standard answer.
How we build receivers
- Verify first. The signature or token is checked before the body is trusted, so forged requests are dropped.
- Answer fast. The endpoint stores the event and replies quickly, then a background worker does the slow part, so the sender does not time out.
- Ignore repeats. The event ID is recorded. If it arrives again, the second copy is acknowledged and discarded.
- Keep failures visible. Events that cannot be processed go to a failed list with the reason, and can be replayed after a fix.
- Handle order. Where the sequence matters, the receiver checks timestamps or version numbers, because delivery order is never guaranteed.
Four ways to build one integration.
The right tool depends on complexity, volume and who will own it. We recommend the simplest option that will hold up.
| Criteria | Best fit | Watch out for |
|---|---|---|
| Native feature | One system, one owner, simple action | Little visibility across systems |
| Visual platform | Multi-step flows that staff must read | Per-task fees and hidden complexity |
| Custom code | Validation, scale or unusual formats | Needs hosting, logging and an owner |
| Human review step | Risky or unclear decisions | A queue that nobody checks |
Connecting a WordPress site to the rest.
WordPress offers several places to attach an integration. Choosing the right one keeps the site fast and the code easy to update.
Options we choose between
- Core REST API. Used when another system should read or write posts, products or users, with authentication and capability checks on every route.
- Custom endpoints. Added through a small plugin when the default routes do not fit, and never by editing core or theme files.
- WooCommerce hooks and webhooks. Order, customer and product events are caught at the right moment, then sent on with retries.
- Scheduled sync jobs. Heavy imports run in the background through Action Scheduler or server cron, so visitors never wait for them.
Larger plugin work is handled by our custom WordPress plugins service, and recurring data pulls by scheduled data pipelines.
What you receive when it goes live.
An integration is something your team will live with for years. We deliver it with the material needed to run it.
Included in the hand-over
- Documentation. A plain description of every flow, field and credential location, written for the next developer.
- Logs and alerts. A searchable record of each message and alerts for failure rates, not only for total outages.
- Secret handling. Keys live in encrypted storage with a rotation note, and never in code or workflow fields.
- A replay tool. A safe way to resend failed records once the cause is fixed.
- Test cases. Sample payloads and expected results so future changes can be checked quickly.
Where a visual tool is a better fit, we build it in n8n or Make and apply the same standards.
Integration questions, answered.
Straight answers to what clients ask before they start.
What is the difference between an API and a webhook?
An API is a set of requests you can make to another system whenever you want data or want to change something. A webhook works the other way: the other system sends you a message when something happens. Most real integrations use both.
What should the integration cost?
Cost depends on how many systems are involved, how well the API is documented, how much data moves, how many exceptions exist and what monitoring you need. We price after reading the API documentation, not before.
Can you integrate a system that has no API?
Sometimes. Options include file exports, database access with the vendor's permission, or an email or CSV hand-off. We explain the risks of each, and we avoid screen scraping unless the terms allow it.
What happens when the other system is down?
Messages wait in a queue and are retried with increasing delays. If the outage is long, an alert goes to a named person and the backlog is replayed in order once the system returns.
How do you prevent duplicate orders or contacts?
Each write carries an idempotency key or a stable external ID, and the receiver checks it first. Duplicate delivery is treated as normal, not as a rare event.
Who owns the code and the credentials?
You do. Repositories, accounts and keys are created in your organisation's name, and we work through limited access that can be removed.
How long does an integration take?
A single, well-documented connection can take a couple of weeks, while several systems with data clean-up take longer. Waiting for vendor sandbox access and approvals is often the slowest part.
Do you maintain integrations after launch?
Yes, if you want it. APIs change versions and rotate keys, so a small maintenance plan that checks logs and updates connections is usually worth having.
