API Integrations

Connect WordPress to Your Business Tools Without Fragile Glue Code

I build and harden API integrations that connect WordPress with CRMs, payment tools, product systems, and custom workflows. You get reliable data flow, error handling, and monitoring so your team isn't debugging silent failures every week.

The Problem

Most Integrations Break Because Nobody Owns Failure Paths

Teams usually wire a happy path, then move on. That's fine until the third-party API rate-limits, payloads change, or a webhook is delayed. I build for the messy reality, because production is always messier than staging.

Records look synced, but field mapping drift slowly corrupts your pipeline.

Silent failures Events fail in the background and nobody knows until revenue reporting breaks.

Off-the-shelf connectors cap what you can do and become bottlenecks later.

Process

How Execution Works

Step 01

Scope

Define required systems, data fields, and business outcomes.

Step 02

Design

I write flow diagrams, field maps, and edge-case handling logic.

Step 03

Build

I develop the connector with security and failure controls in place.

Step 04

Stabilize

Monitor, patch edge cases, and lock maintenance ownership.

FAQ

Common questions

What kinds of API integrations do you handle?

CRM (HubSpot, Salesforce, Pipedrive, Zoho, Close), ERP (SAP, NetSuite, Odoo, Tally, Zoho Books), payment (Stripe, Razorpay, PayU), shipping (Shiprocket, Delhivery, ShipStation), email (FluentCRM, ConvertKit, Mailchimp), AI (OpenAI, Anthropic, Cohere, Replicate), and custom APIs from your business systems. Two-way sync where it makes sense.

REST or GraphQL — which should I pick?

REST for most WordPress integrations — broader plugin ecosystem, simpler to debug, lower learning curve. GraphQL via WPGraphQL when you’re building a headless front-end (Next.js, Nuxt) and need to fetch nested data efficiently in one request. Headless WordPress with no GraphQL is painful; everything else REST handles fine.

Can you build custom REST API endpoints?

Yes. Custom endpoints with proper schema validation, permission_callback authentication, rate limiting, and OpenAPI documentation. Common patterns: webhooks for external systems to push to WordPress, custom data endpoints for mobile apps, business-logic endpoints that compose data from multiple sources, and bulk-operation endpoints that don’t time out PHP.

How do you handle authentication?

Application Passwords for site-to-site (built into WP core). JWT for mobile apps and SPAs. OAuth2 for third-party integrations. WordPress nonces for in-site AJAX. The right choice depends on the consumer — I’ll spec it during discovery.

What about webhooks — both inbound and outbound?

Both supported. Outbound (WordPress notifies external systems): WP fires on post/order/user events, payload signed with HMAC, retries on failure with exponential backoff, dead-letter queue for failed deliveries. Inbound (external systems push to WordPress): signed-payload verification, idempotency keys to prevent duplicate processing, queue-based processing for slow operations.

Will the integration handle high traffic?

Designed to. Background processing for slow operations (Action Scheduler instead of synchronous PHP), Redis-backed caching for repeated API reads, rate limiting per consumer, and circuit breakers for failing third-party APIs. Most integrations I build comfortably handle 100K+ events/day on standard WordPress hosting.

Can you integrate AI APIs (OpenAI, Anthropic) into WordPress?

Yes. Common patterns: AI content generation in the editor, AI-powered search via embeddings + Pinecone/Weaviate, AI customer support chat, and AI-assisted moderation. Implementation includes proper prompt engineering, cost monitoring, response caching, and fallback to non-AI flows when the API is rate-limited or down.

Pricing?

Single integration (one direction, one system): $1,500–$3,500. Two-way sync with webhooks and conflict resolution: $4,000–$10,000. Multi-system integration hub with custom endpoints: scoped per project. Includes documentation, error monitoring setup, and 30-day stabilization window.
