Systems that talk,and say something when they stop.
Most integration projects fail quietly. The sync worked in testing, then a token expired at 2am and nobody noticed for a fortnight. We build the retry, the dead-letter queue and the alert as part of the job, not as a later phase.

In short
Byteinfy builds and connects APIs from $1,500: REST and GraphQL services, webhook pipelines with retries, and integrations with the systems that have no API at all, each one monitored and alerting when it breaks.
Last updated 8 September 2026 · Written by the Byteinfy team, which builds and operates SwipeReel and myBillPlease.
Who it is for
- Businesses re-keying the same data into two systems by hand
- Products that need a public API for customers or partners
- Teams integrating with a vendor whose API is undocumented or hostile
- Anyone whose existing sync breaks often enough that someone checks it every morning
What you get
- REST or GraphQL API with authentication, versioning, rate limits and OpenAPI documentation
- Integrations with Shopify, payment gateways, ERPs, CRMs, logistics and accounting systems
- Webhook receivers built idempotent, so a redelivery does not double-charge or duplicate a record
- Retries with backoff and a dead-letter queue for the messages that still fail
- Monitoring and alerting on every scheduled job, so a silent failure is not silent
- A written data map: which field in system A becomes which field in system B, and who wins a conflict
How it works
- 1
Map
Both systems' data models on one page, with the conflicts and the ownership rules decided before code.
- 2
Build
The happy path first, then the failure paths, which is where integrations actually live.
- 3
Watch
Two weeks of monitoring on real volume before we call it done.
Pricing
From $1,500
A single integration between two systems is $1,500 to $3,500. A public API with documentation, keys and rate limits is quoted on the surface area.
Questions we get asked
- What if the other system has no API?
- Then we look at exports, database access, SFTP drops or, as a last resort, browser automation — and we tell you plainly how fragile each option is before you choose.
- Do you use iPaaS tools like Zapier or Make?
- Where they fit, yes, and we will say so rather than bill you for code. They stop fitting at volume, on complex mapping, and when you need real error handling.
- Who holds the credentials?
- You do. Keys live in your secret store, and we work with scoped access that you can revoke without calling us.
