Custom Lime CRM integration development
Appfront builds custom Lime CRM integrations that connect your relationships, deals and service processes with your website, ERP or own application. Through the Lime CRM REST API and webhooks, we synchronise companies, contacts and the sales pipeline in both directions. Your CRM data stays up to date without duplicate work, and your team works from one reliable view of the customer.
What is a Lime CRM integration?
Lime CRM is a B2B CRM from the Swedish company Lime Technologies, offering functionality for sales, marketing and customer service. It is an industry-specific system that can be adapted to the way your sector works, whether utilities, property, wholesale or manufacturing. Lime Technologies is a European supplier with, among other offices, one in the Netherlands.
In practice, a custom integration means synchronising companies, relationships and contact persons between Lime CRM and your other systems, updating deals and the sales pipeline programmatically, and responding to events in the CRM in real time via webhooks. This avoids manual re-keying and keeps every system, and every team member, working from the same up-to-date customer picture.
Appfront builds according to the official Lime CRM REST API documentation and the OWASP ASVS security standard. We align data mapping, synchronisation direction and error handling with your actual processes, so the integration grows with your organisation and continues to run reliably even at higher volumes.
One up-to-date view of the customer
Relationships, companies and contact persons stay consistent between Lime CRM and your website, ERP or own application. Changes flow through automatically, so sales and service always work with the same, current data.
Real-time via webhooks
With the Lime CRM webhooks add-on, your system responds immediately to new, changed or deleted objects. No slow overnight batches, but events that trigger the right follow-up action straight away.
Web-to-CRM lead capture
Forms and enquiries on your website automatically land in Lime CRM as a relationship or lead, complete with the correct fields and source. No leads lost in an inbox, but a direct place in the sales pipeline.
Our development process for Lime CRM integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your data flows, Lime configuration and adjacent systems through to go-live and ongoing management, every step is aimed at an integration your team can understand and trust.
We map out which Lime types and fields you want to connect, which direction the data should flow, which systems are involved, and which events need to be handled in real time via webhooks.
We design the integration architecture, choose the right authentication and draw up an error-handling strategy.
Implementation with automated tests, structured logging and monitoring. You see working builds along the way.
Controlled go-live with data validation and a safety net, followed by ongoing management and further development.
What a Lime CRM integration delivers in practice
Every Lime CRM integration is set up specifically for your data model, sales and service workflows, and adjacent systems. Below are the capabilities we most often deliver for organisations that use Lime CRM at the heart of their customer processes.
Lime CRM REST API
We build on the official Lime CRM REST API, including the Limeobject, Limetype, File and Query APIs, for reading, creating and updating objects and metadata. Authentication runs through an API key managed in Lime, with retry and error handling tuned to the rate limits.
Relationships, companies & contacts
Two-way synchronisation of companies and contact persons between Lime CRM and your ERP, invoicing or own application. With clear data mapping and deduplication logic, we prevent duplicate records and keep one reliable source of customer data.
Deals & sales pipeline
Deals and their stages are created and updated automatically from your other systems, and changes in the pipeline flow back. This way Lime CRM always reflects the current status of every opportunity, without manual updates.
Webhooks & events
With the Lime CRM webhooks add-on, your system subscribes to new, update, delete and restore events for Limetypes and custom events. Payloads are signed with a secret, so you can reliably validate their origin and content.
Add-ons & marketing
Lime CRM offers add-ons for email, events and surveys via Lime Marketing, among others. We connect these to your processes, for example form responses and participant statuses that come back into the CRM as marketing activity.
Web-to-CRM lead capture
Contact, quote and sign-up forms on your site land directly as a relationship or lead in Lime CRM, with source, campaign and the correct fields. Your pipeline fills automatically, so no enquiry gets stuck in a mailbox.
Typical use cases in practice
A Lime CRM integration turns out very differently for each organisation. We see a number of recurring patterns — suited to the sectors where Lime CRM is strong — and for each of them we have a working setup that pays attention to data mapping, sync direction and webhook events.
B2B sales teams
Sales organisations that manage their pipeline in Lime CRM and want to capture leads from their website and marketing automatically. Web forms land as relationships, deals are updated and status flows back to the adjacent systems. See also our API integrations.
Utilities & energy
Energy and utility companies use Lime CRM for customer and contract management. We integrate the CRM with billing and core systems, synchronise connections and contacts, and process service requests via webhooks so the right department can act straight away.
Real estate
Property and real estate organisations manage relationships, assets and maintenance requests in Lime CRM. We connect it to portals and management systems, so enquiries via the website automatically arrive as a relationship and task in the CRM and nothing falls through the cracks.
Professional services & manufacturing
Service providers, wholesalers and manufacturers that track orders, projects and accounts in Lime CRM. We synchronise companies, contacts and deals with ERP and order management, so sales and operations work from a single view of the customer without duplicate entry.
Technology we use
We build Lime CRM integrations using the official REST API and the webhooks add-on, combined with the backend stack that suits you. The exact choice depends on your data flows and adjacent systems, so that your own team can manage or further develop the implementation.
Why choose Appfront for your Lime CRM integration?
Appfront has extensive experience building API integrations for a wide range of organisations in the Netherlands. We always start with a thorough analysis of your existing systems and processes. An integration should not only work technically, but also add practical value to the way you work.
For every integration, we write clear documentation and make sure your own team, or any future supplier, can understand and manage it. No black box, just transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical and the functional side. This keeps communication short, prevents misunderstandings and speeds up decisions when choices need to be made during development.

Security and privacy in Lime CRM integrations
A CRM almost always holds personal data about customers and contact persons. An integration that exchanges this data therefore requires careful security. Appfront builds to the OWASP ASVS: API keys in secure vaults, validation of webhook signatures using the Lime secret, scoped permissions, encryption in transit and regular audits of the data flows.
We document which data flows through the integration, in which direction and for what purpose, so that your record of processing activities is complete and you can demonstrate compliance with the GDPR. Lime Technologies is also a European vendor, which helps keep your CRM data within the EU and processed there.

- Encryption in transit (TLS 1.2+) and at rest
- Role-based access and least-privilege principles

Frequently asked questions about Lime CRM integrations
Answers to the questions we are asked most often about Lime CRM implementations.
A Lime CRM integration is a technical link between Lime CRM and another system, such as your website, ERP, marketing tool or own application. Via the Lime CRM REST API (Limeobject, Limetype, File and Query APIs), relationships, companies, contacts and deals are read and updated programmatically. With the webhooks add-on, your system receives real-time events when objects are created, changed or deleted. An integration can be small (web-to-CRM lead capture) or broad (two-way sync with your ERP and pipeline automation).
Lime CRM suits B2B organisations that want to bring sales, marketing and customer service together in one industry-specific CRM. It is widely used in sectors such as utilities and energy, property, wholesale, manufacturing and professional services. Its strengths are adaptability to each industry and an open REST API plus webhooks, which allow it to fit well within an existing systems landscape. Whether Lime CRM is right for you depends on your processes, and we are happy to think that through with you.
A simple integration, such as web-to-CRM lead capture that creates forms as relationships in Lime CRM, can go live within a few weeks. Broader scenarios involving two-way sync of companies and contacts, deal and pipeline automation, and webhook-driven workflows into your ERP usually take longer. After an intake meeting, we give a realistic estimate based on your situation.
We work with the official Lime CRM REST API (Limeobject, Limetype, File and Query API) and the webhooks add-on, combined with the backend stack that suits you: Node.js, Python, PHP, .NET, Ruby or Go. Authentication runs via an API key managed within Lime CRM. We validate webhook payloads using the supplied secret signing. We take Lime CRM Cloud's rate limits into account and design retry and error handling accordingly.
The cost is determined by the complexity of the data flows, the number of systems to connect, the desired direction and frequency of synchronisation, and the amount of custom business logic. Ongoing maintenance, monitoring and support also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation.
