Connect Microsoft Dynamics 365 Business Central

Your application calls one EchoRelay URL. When Microsoft Dynamics 365 Business Central changes its API, you update the mapping, not your application.

How Microsoft Dynamics 365 Business Central signs requests

Service-to-service sign-in uses the OAuth 2.0 client credentials flow: an app registered in Microsoft Entra ID gets a token from the Entra token endpoint, with the client ID and secret in the form body.

Can you connect it today?

Yes. Add an OAuth client-credentials credential with your Microsoft Entra token URL and scope, sending the client ID and secret in the form body.

A sample mapping

Your application sends the first request below. The mapping turns it into the body of POST /v2.0/{tenantId}/{environment}/api/v2.0/companies({companyId})/customers, shown second.

Your request

{
    "name": "Fabrikam Ltd",
    "email": "ap@fabrikam.example"
}

What Microsoft Dynamics 365 Business Central receives

{
    "displayName": "Fabrikam Ltd",
    "email": "ap@fabrikam.example"
}

The mapping

{
    "$schema": "https://schemas.echorelay.dev/transform/mapping/v1.json",
    "root": {
        "type": "object",
        "id": "root",
        "properties": {
            "displayName": {
                "type": "field",
                "id": "display-name",
                "path": "name"
            },
            "email": {
                "type": "field",
                "id": "email",
                "path": "email"
            }
        }
    }
}

The grammar, the answer mapping and the dry run are in the mapping docs.

What you bring

This is not a ready-made connector. You bring a sample request or Microsoft Dynamics 365 Business Central’s OpenAPI document, you or your agent write the mapping, and we run the integration you define.
