Data integration & APIs

Your system landscape grew over time. We fit into it.

No company starts on a green field. There is an ERP that has been running for twelve years. A point-of-sale system nobody wants to touch. An association system with exactly one person who understands it.

A marketing system that demands you replace all of it is not a solution. It is a second problem.

Caymland M4 is built as an open system from the ground up. Every capability you see in the interface is available through the API as well. Not as an add-on but as the foundation: the interface itself talks to the system exclusively through that same API.

That has a practical consequence which is often underestimated. There is no capability that exists only "by clicking" and is missing when you automate.

Ready-made connections for the common cases

Where standards exist, we use them.

• CRM systems: Salesforce, HubSpot, Microsoft Dynamics, Pipedrive, Zoho, SugarCRM, vTiger, Connectwise
• Email and calendar: Microsoft 365 and Google, including modern authentication
• Communication services: delivery providers for email, SMS, messenger and WhatsApp, web push
• Advertising platforms: hand audiences to Meta, pull advertising figures back
• Data enrichment: complete company and contact data from external sources
• Storage: Amazon S3 and compatible services for files and media
• Document editing: edit Office documents straight in the browser
• Automation services: a connection to Zapier for hundreds of further applications
• Analysis: product analytics and behavioural data from connected tools

And an open door for everything else

The interesting part is usually not the standard connector but your special case. The industry software. The booking system that grew over the years. The database where the actual truth lives.

For that there is:

• A complete REST API for contacts, companies, segments, campaigns, emails, forms, content, files and everything else. Read, write, in batches too.
• Modern authentication through OAuth, tokens or your corporate login, with finely controllable permissions per access.
• Webhooks that notify your system the moment something happens here. With a queue and a log, so nothing is lost when the other end does not answer.
• Scheduled routines for systems that offer no API and only deliver files.
• Import and export in the usual formats, with field mapping and an error log.

We have built connections to ticketing systems, point-of-sale systems, reservation systems, association software and industry-specific applications. If your system can give data out, we get it in.

Your AI tools may dock as well

Interfaces have so far been built for programs. Caymland M4 has one for AI assistants on top.

Through the open MCP standard, tools your company already uses can work directly with your marketing data: find campaigns and segments, retrieve evaluations, create and adjust content. Your team asks in the AI tool they know, and the answer comes from Caymland M4.

It is secured like any other access: sign-in through OAuth, the unchanged permissions of the person behind it, an approval step before every writing action, and a complete log. A bulk read of the contact base is deliberately not provided for.

Data flows both ways

An integration that only imports creates data graveyards. Caymland M4 works in both directions:

• In: customers, purchases, bookings, contracts and service cases enrich the contact profile and become usable for segmentation and automation immediately.
• Out: reactions, scores, stages, consents and interests flow back, so your sales team can work in the system it knows.

One thing matters here: matching happens cleanly on your unique identifiers, and duplicates are recognised instead of multiplying with every run.

Who changed what, and when, stays visible

Automatic data flows are convenient until something unexpected happens. That is why Caymland M4 logs changes together with their origin. You see whether a field was set by a person, a campaign or an interface. That spares you the most awkward question of all: "where does this value actually come from?"

What this looks like day to day

The ticketing provider. Every booking flows automatically into the contact profile. Marketing segments on it, without anyone ordering an export.

The wholesaler. Revenue and customer groups come out of the ERP; interests and reactions from marketing go back. Field sales sees both in the CRM it knows.

The association. Membership administration stays the system of record. Caymland M4 takes on the communication and reports address changes and unsubscribes back.
