Extend through the developer API." canonical_url: "https://mercemur.com/integrations" last_updated: "2026-09-15" --- # Integrations that work on day one The integrations a real ecommerce business needs, already wired in. Everything else stays programmable. ## Extensibility without marketplace dependency Commerce without ecosystem dependency. Core capabilities are first-party. Everything else remains programmable through APIs, webhooks, MCP and enterprise integrations. Extensions exist, and Mercemur connects to plenty of them. The difference is that Mercemur does not require an extension marketplace to make the core platform useful. Catalog, inventory, orders, customers, promotions, marketing, returns, loyalty, digital products, subscriptions and the storefront are first-party capabilities, maintained as part of the platform rather than bought separately. Beyond that core there are four routes out: native integrations where they make sense, REST and webhooks for everything else, MCP for agent-driven workflows, and enterprise integration work for the unusual requirements. Some things — SMS, WhatsApp, push, external systems of record — are integrations rather than native functionality, and are listed as such. ## Payments Four real payment integrations, each maintained as part of the platform: ### Stripe International cards (Visa, Mastercard, AMEX, Discover, JCB, UnionPay) Apple Pay and Google Pay Refunds (full and partial) with reconciliation Dispute notifications Subscription billing for digital products Runs on your own Stripe account using a restricted key you supply No platform fee is taken from the charge; it lands in your account in full Standard published Stripe rates apply ### Razorpay UPI (PhonePe, Google Pay, Paytm, BHIM, every UPI app) Cards (Visa, Mastercard, AMEX, RuPay) Net banking (every major Indian bank) RuPay credit and debit cards Refund handling Webhook handling for refund.processed and other lifecycle events Settlement directly to your Razorpay account Standard published Razorpay rates apply ### Dodo Payments Cross-border merchant-of-record Tax compliance (VAT, sales tax, and local equivalents) handled by Dodo on your behalf Useful for selling digital products globally without registering for local tax in every country Per-merchant API key model Dodo's published rates apply ### Adyen Hosted Checkout sessions on your own Adyen merchant account Refunds (full and partial) with reconciliation Chargeback, chargeback-reversal and manual-review notifications by webhook Account discovery, so the right merchant account is selected when you connect Test and live environments, validated when the credentials are saved Standard published Adyen rates apply ### Manual payments Cash on delivery Wire transfer Cheque Trade credit (net 30, net 60) Offline reconciliation Same order timeline as processor-based payments ## Shipping ### ShipRocket (India) Single integration, full Indian courier network access Rate comparison at order time Auto-generated AWB numbers and labels Pickup scheduling COD support Reverse pickup for returns Real-time tracking updates ### ShipEngine (international) Global carrier aggregator USPS, FedEx, UPS, DHL, Royal Mail, Canada Post, Australia Post, and many regional carriers Compliant international labels with customs declarations HS code support Rate quotes across multiple carriers per shipment Tracking number generation ### Manual fulfillment In-store pickup Local delivery Drop-shipping White-glove delivery Freight and palletized shipping Auto-generated packing slips ## Email ### Resend Transactional email (order placed, shipped, refund, password reset) Marketing campaigns with audience targeting Per-merchant sender domain (your deliverability is your own) DKIM and SPF setup guidance built into the admin Open and click tracking Bounce and complaint tracking Real-time delivery events High deliverability infrastructure ## Analytics ### Google Analytics 4 Full ecommerce event tracking (view\_item, add\_to\_cart, begin\_checkout, purchase, and more) Consent mode integration so customer cookie choices are honored Standard page view and engagement events No configuration overhead, the integration handles event mapping correctly ### Meta Pixel ViewContent, AddToCart, InitiateCheckout, Purchase events Search and AddToWishlist events Fires automatically based on storefront actions Attribution for Facebook and Instagram ad campaigns ## Storage Digital product file delivery uses secure cloud storage with short-lived signed links. Files do not leave the platform's controlled storage perimeter except through signed delivery to the customer who paid for them. ## Why pluggable Every category (payment, shipping, email) is built around pluggable integrations. If a merchant on Enterprise needs: A different payment provider in a region the built-in three do not cover well A custom shipping carrier (3PL, warehouse partner, freight broker) A different email infrastructure for a niche use case Custom analytics for an internal dashboard The platform supports adding integrations through the developer API. The default integrations cover most merchants. Anyone with a specific need builds against the same public API, on their own infrastructure and their own schedule. ## How to connect Each integration has its own admin connection flow: 1 Stripe. Restricted key flow. Create a restricted key in your Stripe dashboard, paste it into the admin, and charges run on your own account. 2 Razorpay. API key flow. Generate API keys in your Razorpay dashboard, paste into the admin. 3 Dodo. API key flow. Generate API keys in your Dodo dashboard, paste into the admin. 4 Adyen. API credentials flow. Enter your Adyen API credentials, account discovery selects the merchant account, and they are validated on save. 5 ShipRocket. Account credentials flow. Enter your ShipRocket login, the integration handles the rest. 6 ShipEngine. API key flow. Paste your ShipEngine key into the admin. 7 Resend. Domain setup flow. Add your sender domain, follow the DKIM and SPF setup guide, verify. 8 GA4. Measurement ID flow. Paste your GA4 measurement ID into the storefront settings. 9 Meta Pixel. Pixel ID flow. Paste your Meta Pixel ID into the storefront settings. Each connection is per-merchant. Multi-tenant isolation means your credentials are your own, not shared with other merchants on the platform. ## How integrations work together A complete order flow touches multiple integrations: 1 Customer visits the storefront : GA4 and Meta Pixel fire page view 2 Customer adds to cart : Meta Pixel fires AddToCart 3 Customer checks out : Meta Pixel fires InitiateCheckout, GA4 fires begin\_checkout 4 Customer pays through Razorpay (India) or Stripe (international) 5 Payment captures : the full amount lands in your own Stripe or Razorpay account, with no Mercemur cut 6 Order completes : GA4 fires purchase, Meta Pixel fires Purchase 7 Resend sends order confirmation under your sender domain 8 ShipRocket (or ShipEngine) gets a shipment request 9 Carrier label generates, tracking number assigned 10 Resend sends shipped notification with tracking link All of it happens automatically. No glue code, no manual reconciliation. ## Use cases ### India DTC brand Razorpay for payments, ShipRocket for shipping, Resend for email, GA4 and Meta Pixel for analytics. One platform handles the full operation. ### International software vendor Stripe for payments (subscription billing for SaaS), Dodo for cross-border tax compliance on certain regions, Resend for transactional and marketing email, GA4 and Meta Pixel for traffic and conversion attribution. ### Multi-region brand Razorpay for India region, Stripe for US and EU regions, Dodo for the rest of the world. ShipRocket for India shipments, ShipEngine for international. Resend for email under a multi-region sender domain setup. ### Subscription box business Stripe subscriptions for recurring billing. ShipEngine (or ShipRocket if in India) for monthly box shipments. Resend for transactional and pre-shipment emails. GA4 and Meta Pixel for acquisition. ### Multi-brand operator Each brand has its own Stripe, Razorpay, ShipRocket, Resend, and GA4 accounts. The platform routes each brand's traffic and transactions to the brand's own provider connections. ### Agency Each client store connects its own provider accounts. The agency operator has admin access without needing access to the client's actual Stripe or Resend credentials. ## Native connectors on the roadmap These are first-party connectors we intend to build and maintain. They are roadmap directions, not commitments, and depend on merchant demand. Anything listed here can already be integrated today through the developer API, covered in the next section. Additional payment providers for specific regional markets Additional shipping aggregators for non-India, non-US-international markets SMS and push notification channels Marketplace integrations (eBay, Amazon, Etsy) Social commerce (Instagram Shopping, TikTok Shop) ERP integrations Accounting integrations (QuickBooks, Xero) ## Custom integrations through the developer API If the built-in integrations do not cover your need, or a maintained native connector is still on the roadmap, the integration is available today through the API: The platform exposes a developer API for custom integrations Custom payment providers, custom shipping carriers, custom email providers, custom analytics, all possible Provider SDK simplifies the integration work Available on Enterprise plans ### Common custom integrations Warehouse management systems (WMS) Enterprise resource planning (ERP) Customer relationship management (CRM) Marketing automation (HubSpot, Marketo) Loyalty programs Tax engines (TaxJar, Avalara) Custom payment gateways for specific regional markets ## Frequently asked questions Can I add a custom integration? Yes. Every category (payment, shipping, email, analytics) is built around pluggable integrations. Custom integrations are available through the developer API on Enterprise plans. Are these integrations included in the base price? Yes. You pay the underlying provider (Stripe, Razorpay, ShipRocket, Resend, and so on) at their own rates. Mercemur does not charge extra for the integration itself. Can I use my existing Stripe account? Yes. The Stripe integration connects to your existing Stripe account through a restricted key you create in your Stripe dashboard and paste into the admin. Charges land in that account. Can I use my existing ShipRocket account? Yes. Connect with your ShipRocket login. Can I switch payment providers later? Yes. Add or remove providers any time. The order timeline references the provider used at order time. Can I use multiple payment providers simultaneously? Yes. Stripe for international, Razorpay for India, Dodo for cross-border merchant-of-record, Adyen where you consolidate acquiring across markets. The checkout shows the right provider based on the customer's region. Can I use a custom email provider instead of Resend? On Enterprise plans, custom email providers are available through the developer API. What if my shipping carrier is not supported? Custom carriers integrate through the developer API on Enterprise plans. Manual fulfillment is always available as a fallback. Do you charge for API calls? API requests are a metered dimension on Growth and Enterprise plans. Free includes an API request allowance. Do you support webhooks for custom integrations? Yes. Mercemur emits webhooks for major events (order placed, payment captured, fulfillment shipped, entitlement granted, and more). Webhook outbox is SSRF-hardened and signed. Can I integrate with a CRM like HubSpot or Salesforce? Yes through the developer API. Custom integrations are available on Enterprise. Can I integrate with a tax engine like TaxJar or Avalara? Yes through the developer API on Enterprise plans. The built-in tax module handles most cases without an external engine. Can I integrate with an ERP? Yes through the developer API. How are integration credentials stored? Encrypted at rest. Per-merchant isolation. The platform never logs credentials in plaintext. What happens if a provider has an outage? Each integration is independent. A Razorpay outage does not affect Stripe orders. A ShipRocket API issue does not block ShipEngine shipments. Can I test integrations in a sandbox before going live? Yes. Stripe, Razorpay, ShipRocket, and ShipEngine all support test mode. Configure test credentials in the admin to run end-to-end tests. Do integrations update automatically? Yes. Built-in integrations are maintained by Mercemur. Updates roll out without requiring merchant action. ## Best practices for managing integrations Connect integrations before you need them. Stripe, Razorpay, ShipRocket, ShipEngine, Resend, GA4, Meta Pixel. All of them are free to connect. Have them ready before launch day, not the morning of. Use test mode for every payment provider during setup. Run end-to-end test orders before flipping to live. Catch the credential typos and configuration mistakes that production traffic reveals at the worst time. Set up DKIM and SPF for your sender domain on day one. Email deliverability builds slowly. Start the reputation clock as early as possible. Document your integration credentials in a secure password manager. Stripe keys, Razorpay keys, ShipRocket login, ShipEngine API key, Resend domain config, GA4 measurement ID, Meta Pixel ID. Centralize them somewhere safe. Monitor each integration independently. Each integration has its own admin connection status. Check periodically that all of them are still healthy. A silent integration failure is worse than a noisy one. ## What to connect in what order A clean launch sequence keeps the setup practical: collect money first, fulfill second, then layer in communication and attribution. 1 Day 1 ### Payments first Day 1 ### Payments first Launch sequence Stripe, Razorpay, Adyen, or Dodo. You cannot sell without payments. Connect at least one first. Recommended order 2 Day 2 ### Shipping next Day 2 ### Shipping next Launch sequence ShipRocket and ShipEngine. You cannot ship without carriers. Connect after payments. Recommended order 3 Day 3 ### Email setup Day 3 ### Email setup Launch sequence Resend. You cannot do transactional or marketing email without it. Connect domain, configure DKIM and SPF, verify, start sending. Recommended order 4 Day 4 ### Analytics on Day 4 ### Analytics on Launch sequence GA4 and Meta Pixel. Optional but recommended on day one. Pixels start building data the moment you turn them on. Recommended order 5 Day 5 ### Cross-border ready Day 5 ### Cross-border ready Launch sequence Dodo Payments (if you sell digital cross-border). Cross-border merchant-of-record handling. Useful for international digital sales without local tax registration.
