Connect Msgie with
Your Existing Software
Your CRM, ecommerce store, and business tools should all talk to WhatsApp - automatically. Msgie's REST API, real-time webhooks, and native connectors wire your entire software stack to WhatsApp messaging in hours, not months.
WhatsApp Lives in a Silo While Your Business Runs Elsewhere
Your orders live in Shopify. Your leads live in HubSpot. Your customers live on WhatsApp. Keeping all three in sync manually doesn't scale - and the gaps cost you conversions, retention, and hours of manual work every day.
Data silos create blind spots
When your CRM doesn't know what's happening on WhatsApp, and your WhatsApp inbox doesn't know what's happening in your CRM, your team operates on incomplete information. Support agents apologise for things sales already solved. Sales chases leads support already closed. The customer notices every time.
Manual copy-paste doesn't scale
Someone on your team is manually copying WhatsApp conversations into your CRM, pasting order numbers into WhatsApp, and updating spreadsheets after every customer interaction. That person is your most expensive manual process - and they're the first bottleneck that breaks when volume increases.
Broken workflows mean missed revenue
Every time a Shopify order ships without an automatic WhatsApp notification, a customer calls support. Every time a CRM lead goes warm without a WhatsApp follow-up, a sale goes cold. The automation gap between your business tools and WhatsApp is a direct, measurable revenue leak.
One API to Connect WhatsApp
to Your Entire Stack
Msgie's REST API gives developers full programmatic control over contacts, messages, templates, and conversations. Every resource is accessible via standard HTTP requests with predictable JSON responses - no proprietary SDK required to get started.
Pair the API with real-time webhooks and native one-click connectors, and your existing software stack starts sending WhatsApp messages the same day you integrate.
- Full REST API - create contacts, send messages, manage templates
- Webhooks fire within <200ms with HMAC signature verification
- Native connectors for Salesforce, HubSpot, Shopify, WooCommerce
- Zapier & Make integrations - zero code, 5,000+ app connections
Everything Developers Need to Build on WhatsApp
Msgie gives you a complete API platform - from low-level REST endpoints to high-level native integrations - so every team on your stack can connect WhatsApp at the right abstraction level.
REST API
Full HTTP REST API covering all Msgie resources - contacts, messages, templates, conversations, analytics, and settings. Standard JSON request and response bodies, comprehensive error codes, and versioned endpoints mean your integration stays stable across Msgie releases. API reference documentation with live examples is available to all paid plan users.
Webhooks
Subscribe to real-time events - inbound messages, delivery receipts, read receipts, contact updates, and template status changes - and have Msgie POST them to your endpoint within 200ms. Every payload is HMAC-SHA256 signed so you can verify authenticity. Failed deliveries are automatically retried with exponential back-off for up to 24 hours.
CRM Connectors
One-click native connectors for Salesforce, HubSpot, and Pipedrive push WhatsApp conversation history, contact data, and message events directly into your CRM records - with no middleware required. New contacts captured on WhatsApp appear in your CRM automatically; CRM deal updates trigger WhatsApp follow-ups without manual intervention.
Ecommerce Connectors
Connect Shopify or WooCommerce and automatically send order confirmations, shipping updates, delivery notifications, and abandoned-cart recovery messages via WhatsApp - triggered directly by order status changes in your store, with zero code on your end. Works with existing order fulfilment workflows out of the box.
SDKs
Official Msgie SDKs for Node.js, Python, PHP, and Ruby wrap the REST API in idiomatic language clients - handling authentication, request serialisation, error parsing, and rate-limit back-off automatically. Each SDK ships with a full test suite and usage examples covering the most common integration patterns, so your developers ship faster.
OAuth 2.0
Every API key is a scoped OAuth 2.0 bearer token. Limit each key to only the permissions it needs - read contacts, send messages, manage templates - so a compromised key can't do maximum damage. Keys are rotatable from the Msgie dashboard at any time with instant revocation, and audit logs record every API action against the key that made it.
Connect the Tools Your Business Already Uses
Msgie connects natively to the CRM, ecommerce, and automation platforms your team already runs - with more integrations added every quarter.
What Happens When WhatsApp Talks to Your Whole Stack
When Msgie syncs automatically with your CRM and ecommerce tools, the manual copy-paste that consumes your team's time disappears. Contact data, order statuses, and message history flow between systems in real time - no human middleman needed.
Msgie fires webhook events within 200ms of the triggering action. When a customer replies, your backend knows about it almost instantaneously. When an order ships, the WhatsApp notification goes out before the customer checks their email. Real time means real responsiveness.
Msgie's API infrastructure processes over 50 million API requests every month across all customer integrations. The platform is built for high-throughput production use - not just prototypes. Rate limits, retry logic, and uptime SLAs are designed for business-critical workflows.
What Teams Build with the Msgie API
From simple ecommerce notifications to complex multi-system workflows - the Msgie API handles it all. Here are the most common integration patterns our customers build.
Ecommerce Order Updates
Trigger WhatsApp messages automatically when Shopify or WooCommerce order statuses change - confirmation, shipped, out for delivery, delivered, return processed. Customers stay informed without your team touching a single message.
CRM-Powered Outreach
When a CRM lead moves to a new pipeline stage, automatically send a personalised WhatsApp message. When a deal goes stale, trigger a follow-up. When a contract is won, send a welcome message. Your CRM data drives WhatsApp outreach - no manual triggers.
Custom Internal Tools
Operations teams use the Msgie API to build internal notification tools - WhatsApp alerts when inventory drops below threshold, when a support SLA is about to breach, or when a payment fails. Any internal system that can make an HTTP request can now send a WhatsApp message.
Analytics Pipelines
Use webhooks to stream every message event - sent, delivered, read, replied - into your data warehouse or BI tool in real time. Track campaign performance, response rates, and conversation resolution times alongside your other business metrics without exporting CSVs.
Zapier & No-Code Workflows
Non-technical teams connect Msgie to Google Forms, Typeform, Calendly, Stripe, and 5,000+ other apps through Zapier or Make - without writing a single line of code. When a form is submitted or a payment confirmed, a WhatsApp message fires automatically in under a minute.
Healthcare Appointment Systems
Healthcare providers connect their booking systems to Msgie via REST API to send appointment confirmations, 24-hour reminders, and post-visit follow-ups automatically. Patients receive structured WhatsApp messages instead of SMS - with higher open rates and no phone number spoofing risk.
Build Your First WhatsApp Integration in Four Steps
No complex OAuth flows to implement, no Meta API accounts to configure directly, no webhook infrastructure to build from scratch. Msgie handles all of that - you just call the API.
Generate your API key from Settings > API & Integrations
Log in to your Msgie dashboard and navigate to Settings > API & Integrations. Create a new API key, select the scopes your integration needs (send messages, read contacts, manage templates), and copy your bearer token. API access is available on all paid plans - no separate developer account or Meta approval needed. Your first key is active within seconds.
Connect your app or install a native connector
If you're a developer, pass your API key in the Authorization header and start making REST API calls immediately - full reference documentation with code examples in Node.js, Python, PHP, and cURL is available in the Msgie developer portal. If you're not a developer, install one of Msgie's native connectors for Salesforce, HubSpot, Shopify, WooCommerce, Zapier, or Make in one click.
Map your data and configure your workflow triggers
Define which events in your source system should trigger WhatsApp messages, which contacts should receive them, and which Msgie message templates to use. For native connectors, this mapping is done through a guided UI - no code required. For the REST API, you control the logic entirely in your own application. Set up your webhook endpoint URL to receive inbound events from Msgie in real time.
Monitor delivery, errors, and performance in the API dashboard
The Msgie API dashboard shows every request your integration has made - status codes, response times, payload logs, and error details. Webhook delivery logs show which events fired, which endpoints received them, and which deliveries succeeded or failed (with full retry history). Set up alerts to notify you if your error rate crosses a threshold - so you know about integration issues before your customers do.
Frequently Asked Questions
API access is included on all paid Msgie plans. Once you upgrade, navigate to Settings > API & Integrations to generate your first API key. Keys are scoped per application and can be revoked individually at any time without affecting other integrations. The free trial also includes limited API access so you can test your integration before committing.
Msgie uses OAuth 2.0 bearer tokens. Every API key you generate is a long-lived token scoped to specific permissions - read contacts, send messages, manage templates, and more. Pass the token in the Authorization header as Bearer YOUR_TOKEN. Tokens can be rotated from the dashboard without downtime, and all API actions are logged in the audit trail against the specific key that made them.
Yes. Msgie fires webhook events within 200ms of the triggering action - inbound message received, message delivered, message read, contact updated, template status changed, and more. Every webhook payload is HMAC-SHA256 signed so you can verify authenticity on your server. Msgie automatically retries failed deliveries with exponential back-off over 24 hours, and all delivery attempts are logged in your dashboard.
Msgie has native one-click connectors for Salesforce, HubSpot, and Pipedrive on the CRM side, and Shopify and WooCommerce on the ecommerce side. For everything else - Google Sheets, Slack, Mailchimp, Calendly, Stripe, Typeform, and thousands more - Msgie connects via Zapier and Make without writing a single line of code. And of course, you can connect any custom system directly via the REST API.
Yes. Rate limits vary by plan: Starter allows 100 requests per minute, Growth allows 1,000 requests per minute, and Business plans have custom limits negotiated per account. Your current usage and remaining quota are returned in every API response via the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers - so your integration can back off gracefully before hitting a 429 error.
