Custom CM.com integration development
Appfront builds custom CM.com integrations that connect your app, CRM or platform to conversational commerce: messaging, payments and authentication in one place. Using the CM.com REST APIs and webhooks, you send transactional SMS, WhatsApp Business and RCS messages, deliver OTP codes for 2FA and process payments. You reach customers on the right channel and keep order and customer data neatly in sync.
What is a CM.com integration?
CM.com is a Dutch, publicly listed conversational commerce platform based in Breda. It brings together messaging (SMS, WhatsApp Business, RCS and Voice), payments through its own PSP, authentication with OTP and 2FA, email and a mobile marketing cloud. Where many tools focus on a single channel, CM.com combines communication, payments and verification under one API environment.
In practice, a custom integration means: sending messages programmatically from your own app, webshop or CRM, delivering one-time codes for secure login, processing payments within a conversation, and holding two-way conversations via chatbots or customer service. You capture incoming messages and delivery statuses with webhooks, so order and customer data always stay in sync with your own systems.
Appfront builds according to the official CM.com developer documentation and the OWASP ASVS security standard. We align channels, message templates, opt-in logic and error handling with your actual processes, so the integration grows with your product and remains reliable under peak volumes, such as during a campaign or sale.
Messaging across every channel
SMS, WhatsApp Business, RCS and Voice through a single Business Messaging API. You reach customers on the channel they prefer, with reliable delivery and real-time statuses, from a short transactional notification to a rich WhatsApp conversation.
OTP & 2FA authentication
One-time codes via SMS or Voice for secure login, account verification and transaction confirmation. The OTP/Verification API handles generating, sending and validating codes, so you can offer strong authentication without maintaining a verification flow yourself.
Payments within the flow
Process payments via the CM.com Payments API and PSP, either standalone or within a conversation. Send a payment request via WhatsApp or SMS and let the customer pay straight away, with real-time status returned to your backend via webhooks.
Our development process for CM.com integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your channels, message templates and data flows through to go-live and ongoing management, every step is aimed at an integration your team can understand and trust.
We map out which channels you want to use (SMS, WhatsApp, RCS, Voice), whether OTP/2FA and payments are involved, which triggers should send messages and which order and customer data needs to be synchronised.
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 CM.com integration delivers in practice
Every CM.com integration is tailored to your channels, customer communication and adjacent systems. Below are the functionalities we most often deliver for organisations that use CM.com as part of their communication and commerce process.
Transactional SMS & WhatsApp
Order confirmations, appointment reminders, status updates and delivery notifications sent automatically from your own app or webshop. Messages are triggered by events in your system, with delivery statuses returned in real time via webhooks.
OTP/2FA authentication
One-time codes via SMS or Voice for login, registration and transaction confirmation. Through the OTP/Verification API we generate, send and validate codes, so you offer strong authentication without building a vulnerable verification flow yourself.
Payments integration
Take payments via the CM.com Payments API and PSP, either standalone or within a conversation. Send a payment request via WhatsApp or SMS, let the customer pay straight away, and receive the transaction status back in your backend in real time.
Two-way conversations & chatbots
Capture inbound customer messages via webhooks and route them to your customer service team or a chatbot. Handle replies, follow-up questions and automated flows within WhatsApp or SMS, for support, appointment confirmations or a short survey.
Marketing campaigns & Mobile Marketing Cloud
Targeted campaigns via SMS, WhatsApp, RCS and email, driven by segments from your own data or the Mobile Marketing Cloud. Includes opt-in management and unsubscribe logic, so you can communicate at scale while staying within the rules.
Syncing with order and customer data
Two-way synchronisation between CM.com and your CRM, webshop or ERP. Customer details, opt-in status, conversation history and transactions stay consistent, so messages are always accurate and your team has one complete view of each customer.
Typical use cases in practice
A CM.com integration looks quite different from one organisation to the next. We see a number of patterns recurring, and for each of them we have a proven setup that pays attention to channel choice, opt-in management and correct synchronisation with your order and customer data.
Retail & e-commerce
Webshops that send order confirmations, payment requests and marketing campaigns via SMS and WhatsApp. Customers can pay within the conversation, and the status flows back to the webshop. Combine with a WhatsApp Business API integration or a payment integration via Mollie.
Ticketing & events
Event organisers who send e-tickets, reminders and changes via SMS or WhatsApp, with two-way support for questions just before an event. OTP secures accounts and payments run in the same flow, which is ideal for peak sales around a launch.
Finance & insurance
Banks, fintechs and insurers that use OTP and 2FA for secure login and transaction confirmation, plus transaction alerts via SMS. Strong authentication without having to maintain a verification platform yourself, with an audit trail of every code sent.
Logistics & delivery notifications
Delivery services and logistics platforms that send track-and-trace updates, time-slot confirmations and delivery notifications via SMS and WhatsApp. Customers can reply two-way to change a time slot, and status updates stay in sync with your planning. See also our API integrations.
Technology we use
We build CM.com integrations using the official REST APIs and webhooks, combined with the backend stack that suits you. The precise choice depends on your channels, payment needs and authentication requirements, so that your own team can manage or further develop the implementation.
Why choose Appfront for your CM.com 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.

Security and privacy in CM.com integrations
Customer communication, authentication codes and payments always involve personal data or business-sensitive information. Appfront builds in line with CM.com's security best practices and the OWASP ASVS. That means, among other things: API keys and product tokens stored in secure vaults, webhook signature validation, scoped permissions and regular audits of the messaging, payment and OTP flows.
For messaging, opt-in and consent are paramount: you only send messages to customers who have given permission, with clear unsubscribe logic. CM.com is a Dutch, publicly listed platform holding certifications such as ISO 27001 and PCI DSS for payments. We document the data flows, channels and consent records so that your record of processing activities is complete and you can demonstrate compliance with the GDPR.

Frequently asked questions about CM.com integrations
Answers to the questions we are asked most often about CM.com implementations.
A CM.com integration is a technical link between the CM.com platform and another system, such as your own app, CRM, webshop or platform. Through the CM.com REST APIs, you send messages programmatically (SMS, WhatsApp Business, RCS, Voice), process payments via the Payments API, and deliver one-time codes for OTP/2FA authentication. Webhooks provide real-time updates when a message has been delivered or when a customer replies. An integration can be simple (a transactional SMS for every order) or extensive (two-way conversations, chatbots and payments in a single flow).
CM.com suits organisations that communicate with customers at scale and prefer to handle messaging, payments and authentication through one Dutch, publicly listed platform. Its strength lies in the combination: SMS, WhatsApp, RCS and Voice, plus payments and OTP/2FA, within a single API environment. If you only need one channel, such as WhatsApp alone or payments alone, a point solution may suffice. We will work with you to assess whether the breadth of CM.com genuinely adds value to your situation.
A simple integration, such as sending transactional SMS or WhatsApp notifications via the Messaging API, can go live relatively quickly. More advanced scenarios involving two-way conversations, chatbot routing, payment integration, OTP/2FA and deep synchronisation with order and customer data generally take longer. After an intake meeting, in which we map out your channels and data flows, we give you a realistic estimate.
We work with CM.com's official REST APIs, namely the Business Messaging API for SMS, WhatsApp Business, RCS and Voice, the Payments API and the OTP/Verification API for authentication, combined with whichever backend stack suits you: Node.js, Python, PHP or .NET. Authentication is handled via API key (product token) or OAuth. Inbound messages and delivery statuses are captured using webhooks, with signature validation.
The cost is determined by the complexity of the data flows, the number of channels and systems you connect, the two-way functionality you require and the amount of custom business logic involved. Ongoing management, monitoring and support also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation. The messaging and payment usage fees charged by CM.com itself are separate from the build cost of the integration.
Yes. CM.com is a Dutch, publicly listed platform with certifications such as ISO 27001 and PCI DSS for payments. Appfront builds to the OWASP ASVS standard: API keys and product tokens are stored in secure vaults, webhook signatures are validated, permissions are scoped, and rights are separated per integration. For messaging, we carefully configure opt-in and consent so that you only send messages to customers who have given their permission. We document the data flows so that your record of processing activities stays complete and you can demonstrate GDPR compliance.
Yes. Appfront regularly takes over existing CM.com integrations, even ones originally set up by another party. We review the API integrations, channel configuration, webhook handling and error handling, document the current setup and propose improvements. From that point on, we handle changes, extensions to additional channels and monitoring, including timely rotation of API keys and product tokens.
CM.com suits organisations that communicate with customers at scale: retail and e-commerce (order confirmations, delivery notifications, marketing campaigns), ticketing and events (e-tickets, reminders, two-way support), finance and insurance (OTP/2FA, transaction alerts) and logistics (track and trace, delivery notifications). Typical use cases include transactional SMS and WhatsApp from your own app, OTP authentication at login, payments within a conversation and chatbots for customer service. If you only need one narrow channel, we will check whether a lighter point solution is a better fit.
