Connect STM Express with Maystro in minutes and automate any workflow between them — no code, no developers, no complicated middleware. eGrow ties STM Express and Maystro together over a secure API so when something happens in one, the right thing happens in the other in real time.
Sync customers, orders, statuses and any custom field between STM Express and Maystro, trigger actions across both apps from a single workflow, and unify reporting in one place. Set up in 5 minutes with free white-glove onboarding.
The STM Express and Maystro integration connects STM Express to Maystro through eGrow's no-code automation engine. You build a workflow once — pick a trigger from STM Express, choose an action in Maystro, map the fields — and eGrow keeps both apps in sync from then on, in real time, with no developers required.
Common things teams automate between STM Express and Maystro: sync new STM Express records into Maystro, push Maystro updates back to STM Express, fan out one event in STM Express into multiple actions across Maystro, alert your team in chat when something breaks, and unify customer data so both systems see the same source of truth.
Setup takes about 5 minutes. Sign up for eGrow, authorise STM Express, authorise Maystro, drag-and-drop a workflow between them and turn it on. Free white-glove onboarding is included with every plan — a real account manager will build your first workflow with you over a screen-share.
eGrow is purpose-built for e-commerce and operations teams: the STM Express + Maystro integration runs alongside 100+ other integrations, so you can chain Shopify, WooCommerce, WhatsApp, FedEx, DHL and more into the same workflow when you need them. Everything runs in one secure, GDPR-compliant environment with full run logs, retries on failure and OAuth-based access control.
Sign up for eGrow, authorise both STM Express and Maystro from the Integrations panel, then build a no-code workflow between them. The whole setup takes about 5 minutes.
Any data either app exposes via triggers and actions: events, customer records, orders, statuses and more. The full list is below.
It's included with every eGrow plan — connection costs nothing extra. You only pay your normal STM Express and Maystro plans on each side.
No. eGrow's automation builder is fully no-code. You select a trigger, pick an action, map the fields, and turn the flow on.
Yes. Once STM Express and Maystro are connected, you can chain any other eGrow integration into the same automation — Shopify, WooCommerce, WhatsApp, FedEx and 100+ more.
Real time. eGrow uses webhooks where STM Express and Maystro support them, otherwise polls every 1–5 minutes. Most workflows complete end-to-end in under 2 seconds, so changes in one app reach the other almost instantly.
Yes. Data flowing between STM Express and Maystro is encrypted in transit (TLS 1.2+) and at rest, each app is authorised using whichever method it officially supports (OAuth, API key, or signed webhook), and eGrow is GDPR-compliant with optional regional data residency. We sign DPAs on request.
eGrow retries failed API calls with exponential back-off, deduplicates retries, and surfaces the exact error from STM Express or Maystro in the run log so you can fix it. You'll get an email if a workflow keeps failing — no silent drops.
Yes — authorise as many STM Express and Maystro workspaces as you need and route each automation to the right pair. Useful for agencies, multi-brand operators, and dev/staging environments.
Sign up, authorise both apps, and turn on the workflow. Free white-glove setup with every plan.
