Twenty Integration Services
Twenty integration connects the open-source CRM to the systems your go-to-market team actually runs on — email, calendars, ecommerce, support, payments, and marketing tools. We build on Twenty's REST and GraphQL APIs and webhooks — on Twenty Cloud or your self-hosted instance — as an independent consultancy: we don't sell a connector, so we recommend the approach that actually fits your requirement.
What Is Twenty Integration?
Twenty integration is the process of exchanging data automatically between Twenty and the other applications your team runs, so records like people, companies, opportunities, notes, and tasks stay consistent everywhere without manual re-entry. It's how a new Stripe customer becomes a Twenty record, or a closed-won opportunity triggers a Slack message, in seconds instead of at the next team sync.
Twenty is a modern, open-source CRM — a community-driven alternative to Salesforce and HubSpot, built on a metadata-driven data model. It ships standard objects (People, Companies, Opportunities, Notes, Tasks) and lets you define custom objects, fields, and relations from the UI. The moment you add an object, Twenty auto-generates matching REST and GraphQL endpoints for it, so integrations map onto your exact schema using your own object and field names — there are no opaque IDs to reverse-engineer.
Because Twenty is self-hostable, your CRM can live on your own infrastructure — a real draw for teams with data-sovereignty or compliance requirements. Whether you run Twenty Cloud or a self-hosted instance, integration turns a stack of disconnected tools into a single source of truth, cuts re-keying, and removes the reconciliation errors that come from copying records by hand.
What Can You Integrate with Twenty?
You can integrate Twenty with almost any modern system that exposes an API. The most common categories we work with are email & calendar, ecommerce, payments, support, marketing, and internal notifications — feeding activity and revenue into your CRM automatically.
Email & Calendar
Gmail, Outlook, Google Calendar
Logged emails, meetings, and calendar activity against records
Ecommerce
Shopify, WooCommerce, BigCommerce
Customers, orders, and lifetime value synced to company records
Notifications & Ops
Slack, internal tools, custom systems
Opportunity-stage alerts, new-record pings, and workflow triggers
If your system isn't listed, it's almost certainly still integrable. We scope against your actual requirement, not a connector catalogue.

How Do You Integrate Twenty with Other Systems?
Twenty auto-generates both a REST and a GraphQL API from your workspace, secured with an API key or OAuth, plus a Metadata API for schema and webhooks for event-driven flows on record changes. Around that sit native sync and workflow automation, and iPaaS connectors for teams who don't want to maintain code.
| Approach | What it is | Best for | Watch out for |
|---|---|---|---|
| Twenty REST API (Core) | Auto-generated CRUD over records — People, Companies, Opportunities, custom objects | Straightforward integrations and simple create/update/list flows | Endpoints are per-workspace — nothing is assumed, everything is mapped to your schema |
| Twenty GraphQL API (Core) | The same data with relation traversal, filtering, and batch upserts in one query | Complex, nested syncs and deep bi-directional mapping | Slightly steeper learning curve than REST; worth it for related-object flows |
| Metadata API | Programmatic schema management — create or modify objects, fields, relations | Provisioning custom objects an integration depends on | Schema changes should be version-controlled and reviewed before go-live |
| Webhooks | Twenty push notifications on record create, update, and delete | Triggering downstream flows the moment a record changes | Still fetch the full record over the API after the ping |
| Native sync & Workflows | Built-in Gmail/Outlook & calendar sync plus the visual workflow builder | Standard email/meeting logging and simple no-code automations | Great for activity logging; won't cover custom multi-system mapping |
| iPaaS / Custom middleware | Templates on Zapier/Make/n8n, or purpose-built orchestration over the API | Fast standard flows, or non-standard requirements and AI automation | Subscription cost forever for iPaaS; custom needs a partner who maintains it (that's us) |
The truth most vendors won't tell you: for many standard requirements, Twenty's native sync, its workflow builder, or a pre-built iPaaS template is genuinely the right answer. We'll tell you when that's the case, help you choose and configure it, and only build custom when your object model or workflow demands it.
How Much Does Twenty Integration Cost?
A typical Twenty integration costs between $1,800 and $16,000 to implement, depending on the approach. Templated iPaaS connectors sit at the low end plus a monthly platform subscription; custom REST/GraphQL builds with bi-directional sync and custom-object mapping sit at the high end with no recurring platform fee.
| Approach | Implementation | Ongoing |
|---|---|---|
| Templated iPaaS connector (Zapier/Make) | $1,800 – $5,500 | $30 – $300/month platform subscription |
| iPaaS orchestration (Make, n8n) | $3,000 – $9,000 | $30 – $250/month platform + support retainer |
| Custom REST / GraphQL / webhook build | $6,000 – $16,000+ | Support retainer only, no platform fee |
Four factors move the number most: how many objects you sync (people, companies, opportunities, or custom objects), whether flows are one-way or bi-directional, how much field and relation mapping the workflow needs, and whether you run Twenty Cloud or a self-hosted instance (self-hosting can add firewall/VPN and network work). We quote fixed prices after a scoping call, so you know the cost before we write a line of code.
How Long Does It Take?
The single biggest schedule risk isn't development — it's an undocumented custom-object model and duplicate people/company records in Twenty, which is why data review is the first step of our process.
Templated integrations
Standard record flows on a pre-built connector or iPaaS template against Twenty's API, live fast.
Custom builds
Bespoke REST/GraphQL and webhook work, scaled to object count, workspace structure, and testing depth.
What Does Our Integration Process Look Like?
Every engagement follows the same five stages — you get a fixed-price scope and a mapping sheet you sign off before we build.
Discover
We map your systems, objects, volumes, and the business outcome you need.
Map
We document every field, direction, transformation, and error rule before building.
Build
We implement on the chosen platform or codebase, against a Twenty sandbox workspace.
Test
We run real record scenarios end to end — failure cases, retries, duplicate handling.
Support
We monitor after go-live, with alerting, logging, and a named contact.
Consultant vs. Buying a Connector
A connector vendor can only sell you their connector. An independent consultant starts from your requirement and picks the tool afterwards — which matters most when your custom-object model doesn't match a generic template, or you need webhook-driven, real-time flows against a self-hosted instance.
| Connector vendor | RethinkingWeb | |
|---|---|---|
| Recommends | Their product | Whatever fits, including their product |
| Non-standard requirements | Change requests or workarounds | Custom logic is the core offering |
| Self-hosted Twenty | Often cloud-only | Cloud or self-hosted, firewall/VPN included |
| When it breaks | Support ticket queue | Named engineer who built it |
| Multiple systems | One connector per pair | One orchestrated architecture |
The Team on Both Sides of the Sync
We're an official Twenty CRM partner, and we build and run integrations for companies across the US, UK, Australia, and India. Our team pairs Twenty integration work with deep roots in the platforms on the other side of the sync: we're a WordPress and WooCommerce development agency, and we build AI automation on the Claude API.
Twenty is one hub among several we connect. We also build integrations for Salesforce, QuickBooks, NetSuite, Shopify, and WooCommerce — so whichever system sits opposite Twenty, we know it from the inside.
Why Integrate with RethinkingWeb
Integration only pays off if it keeps running after go-live. These are the reasons companies hand us the connection between their CRM and everything else — and keep us on to look after it.
Official Twenty CRM Partner
We're a recognized Twenty CRM partner and a WordPress & WooCommerce development agency — so we know both sides of the sync, not just the CRM half.
Vendor-Neutral by Design
We don't sell a connector, so we have no reason to push one. We recommend the approach that fits your requirement — even when that means a product we don't earn a cent from.
Cloud & Self-Hosted Experts
Twenty's open-source, self-hostable model is a feature, not a footnote. We integrate Twenty Cloud and self-hosted instances alike, handling the firewall, VPN, and network access that self-hosting brings.
Fixed Price Before We Build
You approve a signed mapping sheet and a fixed quote before a single field is configured. No open-ended hourly meters, no scope surprises mid-project.
A Named Engineer, Not a Queue
The person who built your integration is the person who answers when something changes. No ticket lottery, no re-explaining your setup to a new agent each time.
Proven Across Four Countries
We build and run integrations for businesses in the US, UK, Australia, and India, spanning SaaS, ecommerce, and professional services CRM setups.
Rescue & Take-Over Specialists
A large share of our work is fixing abandoned custom builds, broken Zapier scenarios, and duplicate-record messes. If your last Twenty integration failed, we've almost certainly seen your exact situation.
AI Automation on the Claude API
Beyond moving data, we build AI agents on the Claude API that act on your Twenty records — natural-language pipeline reporting, automated record enrichment, and smart opportunity-stage triggers.
Frequently Asked Questions
Yes. Twenty auto-generates both a REST and a GraphQL API from your workspace data model, plus a Metadata API for schema and webhooks for real-time events. Endpoints use your own object and field names, and authentication is via API keys or OAuth.
Yes. Twenty is open-source and self-hostable, and self-hosted instances expose the same REST, GraphQL, and webhook capabilities as Twenty Cloud. We work with both — for self-hosted we account for firewall, VPN, and network access as part of scoping.
Both hit the same data. We use REST for straightforward create/update/list operations, and GraphQL when a flow needs nested relations, filtering, or batch upserts in a single call. We pick per-flow, so you get the simplest option that does the job.
Twenty ships standard objects (People, Companies, Opportunities, Notes, Tasks) and lets you define custom objects, fields, and relations from the UI. Every object instantly gets matching REST and GraphQL endpoints, so integrations map external data onto your exact structure.
Yes. Syncing Twenty with Stripe, Shopify, and HubSpot is among the most common requests, moving customers, opportunities, invoices, and revenue between the systems automatically.
Twenty supports near real-time flows using webhooks and its REST/GraphQL APIs. Where the other system only offers batch exports or polling, we match the sync pattern to your data volume and urgency.
Yes. Two-way sync of records, fields, and relations is possible, though we design bi-directional flows carefully with clear rules on which system owns each field to avoid duplicate or conflicting records.
Most Twenty integrations land between $1,800 and $16,000 depending on approach, object count, sync direction, and whether the instance is cloud or self-hosted. See the cost table above for a breakdown by method.
Yes. Rescue work is a large share of our practice: broken Zapier or Make scenarios, abandoned custom builds, and duplicate-record messes that no longer match the sales process.
Yes. We connect Twenty to support platforms like Intercom, Zendesk, and Front, syncing tickets, conversation history, and CSAT scores back onto the account record.
