What's Included

Everything you get with our API Integration Plugins

REST API Connections

Secure, authenticated connections to external APIs with proper error handling, rate limiting, and retry logic

Data Synchronization

Bidirectional data sync between WordPress and your external systems with conflict resolution and logging

Webhook Processing

Incoming webhook endpoints that let external services push data to your WordPress site in real time

Our API Integration Process

Integration Mapping

We document what data needs to flow between WordPress and your external systems, in which direction, how often, and what should happen when things go wrong. We review the external service's API documentation and identify the best integration approach.

Authentication and Connection Setup

We implement secure authentication with the external API using the appropriate method: OAuth 2.0, API keys, JWT tokens, or other mechanisms. We establish the connection, test it thoroughly, and configure proper rate limiting.

Data Mapping and Sync Development

We map fields between WordPress and the external system, build the synchronization logic, implement conflict resolution rules, and set up logging so you can monitor data flow and troubleshoot issues.

Testing and Deployment

We test the integration with real data scenarios, verify that edge cases are handled correctly, deploy to your production environment, and monitor the first round of live data exchanges to confirm everything works as expected.

Key Benefits

Seamless System Connections

Your WordPress site connects directly to your CRM, marketing platform, ERP, accounting system, or any service with an API. Data flows automatically without manual copying, middleware fees, or the delays that come with third-party connectors.

Automated Data Exchange

Lead data from forms goes to your CRM instantly. Orders sync to your fulfillment system in real time. Customer records update across all platforms automatically. No more manual data entry, no more systems out of sync.

Reliability and Error Handling

Our integrations include proper error handling, retry logic for failed requests, logging for troubleshooting, and graceful degradation when external services are temporarily unavailable. Your data never disappears silently.

Frequently Asked Questions

What systems can you integrate with WordPress?

Any system with an API. Common integrations include CRMs (Salesforce, HubSpot, Zoho), marketing platforms (Mailchimp, ActiveCampaign, Klaviyo), ERPs (NetSuite, SAP), accounting (QuickBooks, Xero), payment processors (Stripe, Square), shipping (ShipStation, EasyPost), and custom internal tools. If it has an API, we can connect it.

Is a custom integration better than using Zapier?

For simple, low-volume connections, Zapier can work fine. For high-volume data exchange, complex logic, or mission-critical integrations, custom plugins are more reliable, faster, and less expensive at scale. Custom integrations have no per-task fees, no third-party dependency, better error handling, and direct database access for complex operations.

What happens if the external API changes?

API changes are a reality of integration development. We build integrations with version-aware API calls and error handling that detects when something changes unexpectedly. If an external API makes breaking changes, we update the integration. Our maintenance plans include monitoring for API changes and proactive updates.

Can you build bidirectional sync?

Yes. We build bidirectional synchronization with proper conflict resolution. When the same record is updated in both systems, the integration follows rules you define: newest wins, WordPress wins, external system wins, or custom merge logic. Every sync operation is logged for audit purposes.
