How it works

From checkout to a working flow in minutes.

No consultants, no custom development, no waiting for Microsoft certification cycles.

1

Subscribe

Pick a connector and pay by card. Your Westlume key is issued instantly and shown in your account. One key per connector, revocable any time.

2

Install

Download the connector solution and import it into your environment: Solutions → Import. A five-minute guide with screenshots is included.

3

Connect

Create a connection: paste your Westlume key and your own service credentials. They stay in your tenant's connection. We only compute signatures.

Security

Your credentials stay yours.

The proxy exists to do one thing: the cryptographic busywork these APIs demand. It is not a place where your accounting data lives.

Questions about compliance or data processing? Ask us directly. You'll get an engineer, not a chatbot.

Zero credential storage

Your Merit or SmartAccounts keys live in your tenant's connection parameters. Our proxy receives them per request, signs and forwards. Nothing is ever written to disk.

No payload retention

Request and response bodies pass through in memory only. For metering we log timestamps, endpoints and status codes. Never your invoices.

Hosted on Azure, in the EU

The proxy runs on Azure Functions in an EU region, TLS end to end. Keys are revoked the moment a subscription ends.

FAQ

Fair questions.

Does this work in Azure Logic Apps too?

Yes. The same connector definition works as a custom connector in Logic Apps. Your Westlume key works in both, and one subscription covers your tenant.

Do you see or store our accounting data?

Requests pass through our proxy so it can compute the signatures these APIs require. Payloads are processed in memory and never stored. We keep only metering metadata: timestamps, endpoint names and status codes.

Why isn't this a Microsoft-certified connector?

Certified independent-publisher connectors must be free and can't include a hosted signing service, which is exactly the part that makes these APIs painful. Shipping as an importable solution means it works in any tenant today and we can push fixes in hours, not certification cycles.

What happens when I cancel?

Your key stays active until the end of the paid period, then stops answering. The connector remains in your environment, so resubscribing later just reactivates the key. No reinstall needed.

How does the Claude connector handle API costs?

You bring your own Anthropic API key, so token usage is billed directly by Anthropic on your account. Our fee covers the connector, the proxy and keeping up with API changes. We never touch or meter your tokens.

How are the SharePoint web parts licensed?

Per tenant, per year. You get the .sppkg package for your app catalog, plus every update and email support while the license is active. The web parts run entirely inside your tenant and no data leaves SharePoint.

Who builds and runs this?

Westlume is a product of DEKET OÜ (DigiDek), an Estonian Microsoft consultancy. The connectors grew out of real client integrations. We productised the parts every project kept needing.
