API Integrations for Small Businesses
Nyatva connects the systems your business already pays for — CRM, accounting, payments, email, spreadsheets and internal tools — so data moves between them automatically instead of being copied by hand. Integrations are built to handle outages gracefully, with retries, alerting and a log of what synced.
Most small businesses do not need more software. They need the six tools they already own to stop being islands. The cost of that gap is invisible but constant: the same customer typed into three systems, a payment reconciled by hand, a spreadsheet nobody trusts.
Integrations fail in production for boring reasons — an API rate limit, an expired token, a partial outage, a duplicate webhook. We build for those from the start: idempotent writes so a retry cannot double-charge or duplicate a record, exponential backoff, and an alert when something needs a human.
Where a maintained connector already exists and does the job, we will tell you to use it rather than billing you to rebuild it. Custom work is for the parts no off-the-shelf connector covers.
What's included
- Two-way or one-way sync between your chosen systems
- Webhook handling with signature verification
- Idempotent writes so retries cannot duplicate records or charges
- Rate-limit handling and exponential backoff
- Field mapping and data transformation agreed with you
- Error alerting plus a sync log you can inspect
- Backfill of historical data where needed
- Documentation of every endpoint and mapping
Who this is for
- The same information is entered into two or more systems
- Payments or invoices are reconciled manually every month
- You need a tool integration that Zapier or a native connector does not cover
- A previous integration keeps silently breaking and nobody notices for days
How it works
- 01
Discovery call
30-60 minWe discuss your goals, constraints and timeline. We ask a lot of questions, because a problem understood properly is usually cheaper to solve.
- 02
Proposal and fixed quote
1-2 daysYou receive a written proposal with scope, timeline and a fixed price. No hourly billing, no open-ended estimates.
- 03
Build and iterate
VariesWe build with regular check-ins and working previews, so you see progress and can redirect us early rather than at the end.
- 04
Launch and support
OngoingWe deploy, hand over the code and documentation, and stay available through the included support period.
What it costs
Fixed-price per integration, quoted once the endpoints and field mappings are known. Small, well-defined connections are among the cheapest work we do.

Frequently asked questions
Why not just use Zapier or Make?
For simple, low-volume connections you often should, and Nyatva will say so rather than bill you to rebuild it. Custom integration earns its cost when you need complex field mapping, high volume, guaranteed delivery, or an API that no off-the-shelf connector supports properly.
What happens if one of the systems goes down mid-sync?
The integration retries with exponential backoff and holds the pending items in a queue rather than losing them. Writes are idempotent, so a retry cannot create a duplicate record or a double charge. If something still cannot be delivered, Nyatva sets up an alert so a person knows within minutes.
Can you integrate with an old system that has no API?
Often, yes. Where no API exists Nyatva can work with scheduled file exports and imports, database-level access, or a scraping layer as a last resort. Nyatva assesses feasibility during scoping and will tell you plainly if the honest answer is no.
Who owns and maintains the integration afterwards?
You do. Nyatva hands over the code, the documentation and the credentials, all held in your accounts. A support period is included for fixing anything that surfaces after launch, and ongoing maintenance is optional rather than a condition of the build.
