Dynamics 365 Dataverse Web API

Technical Preview

Overview

A client-mode connector for a curated eight-operation slice of the Dataverse Web API used by Dynamics 365 / Power Platform: WhoAmI, account CRUD helpers, contacts, and EntityDefinitions. It is meant for ERP/CRM edge bridges, not the full Dynamics surface. Set BASE_ADDRESS to the customer org URL (for example https://contoso.crm.dynamics.com, or .crm4.dynamics.com for many EU tenants).

Dataverse requires an Azure AD Bearer access token for the org resource. A placeholder org host does not resolve. Unauthenticated global discovery returns HTTP 400 without a tenant.

Basic Syntax

# Coreflux REST_API template — Dynamics 365 (Dataverse Web API)
# Generated from curated OpenAPI; credentials are placeholders only.
# Docs: https://docs.coreflux.org/latest/lot-language/routes/rest-api-routes
# Auth: Azure AD Bearer via {value.json.api_token}. Prefer Hub secrets / GET SECRET.
# BASE_ADDRESS: replace YOUR_ORG (and region: .crm / .crm4 / etc.) with the customer org URL.

List endpoints accept OData query options ($select, $filter, $top, $orderby) when you extend the ENDPOINT or append them in a custom variant.

Auth

Azure AD Bearer plus Dataverse OData headers:

ADD "Accept" "application/json"
ADD "OData-MaxVersion" "4.0"
ADD "OData-Version" "4.0"
ADD "Prefer" "odata.include-annotations=\"*\""
ADD "Authorization" "Bearer {value.json.api_token}"

string

required

Azure AD access token for the Dataverse org resource (audience = org URL). Obtain via client credentials or a delegated OAuth 2.0 flow. Prefer a Hub secret. Never commit the token.

string

Account GUID. Required on Getaccount and Updateaccount.

string

Contact GUID. Required on Getcontact.

High-level token flow (no secrets in the template):

Register an Entra ID app with permission to the Dynamics / Dataverse API (or use an existing app registration).
Acquire a token with client credentials (app-only) or a delegated user flow against the org resource URL.
Publish the access token as api_token on the MQTT request payload (or inject from Hub secret upstream).

WhoAmI:

{"api_token": "YOUR_AZURE_AD_ACCESS_TOKEN"}

Get account:

{"api_token": "YOUR_AZURE_AD_ACCESS_TOKEN", "accountid": "00000000-0000-0000-0000-000000000000"}

Create account (connector body is {payload}; include name):

{"api_token": "YOUR_AZURE_AD_ACCESS_TOKEN", "name": "Contoso Plant"}

Try it

Set BASE_ADDRESS to your org URL and add the connector on your broker.
Publish token JSON to integrations/dynamics365/request/Whoami.
Subscribe to integrations/dynamics365/response/Whoami.
Accounts / contacts: include accountid or contactid as needed.
