Third-Party API Integrations

CRMs, payment gateways, ERPs, marketing tools, and AI APIs all need to talk to your product. We build integrations that handle authentication, rate limits, retries, and data mapping properly, so data stays in sync and failures are visible instead of silent.

This Is For You If...

  • You need your product connected to Salesforce, HubSpot, Stripe, QuickBooks, or similar tools

  • Data between systems drifts out of sync

  • An integration breaks when the provider changes something

  • You hit rate limits or token expiry errors from external APIs



Which Area Matches Your Need?

Ask Yourself

Points Toward

Do you need a new integration built?

Integration Development

Is data out of sync between systems?

Data Sync & Mapping

Do integrations fail on limits or auth?

Resilience & Rate Limits

Do you need many integrations at once?

Integration Platforms



Integration Services We Offer

Integration Development

Connections to CRMs, payments, accounting, ERPs, communication tools, and AI APIs, with OAuth and token refresh handled correctly.

Data Sync & Mapping

One-way and two-way sync, field mapping, conflict rules, and reconciliation reports.

Resilience & Rate Limits

Backoff, queues, batching, and alerting so provider limits and outages don't break your product.

Integration Platforms

Unified APIs, iPaaS tools, or a custom integration layer when you need many connections.



What We Need From You

What to Share

Why It Helps

The systems to connect

Defines APIs and auth methods

What data moves, and which way

Shapes the sync design

Volume and timing needs

Affects batching and rate limits

Account access for testing

Needed to build and verify



Common Mistakes to Avoid

Instinct

Why It Doesn't Help

Do This Instead

Calling external APIs inside user requests

Their slowness becomes yours

Use background jobs where possible

No handling for token expiry

Integrations silently stop

Refresh tokens and alert on failure

Two-way sync without conflict rules

Data overwrites itself

Define which system wins per field

No reconciliation

Drift goes unnoticed

Compare and report regularly



How It Works

1. Map data flows

What moves where, and when

2. Design

Auth, sync, and error handling

3. Build

Integration code and background jobs

4. Test

With real accounts and edge cases

5. Monitor

Alerts and reconciliation



Why Codersarts

We build integrations to keep working after launch — with retries, alerts, and reconciliation — because most integration problems appear weeks later, not on day one.



Turnaround Time

A single well-documented integration is typically built within one to two weeks. Multi-system projects are scoped individually.



FAQ

Which tools have you integrated?

Common CRMs, payment gateways, accounting, communication, and AI APIs; we work from each provider's documentation.

Should we use Zapier or n8n instead?

Sometimes — for simple flows, see Automation Engineering.

Do you maintain integrations?

Yes, ongoing maintenance can be arranged.

Is our project kept confidential?

Yes. Your data, code, and results stay confidential, and an NDA is available on request.
