# Microsoft Dynamics 365 Business Central Connector Reference
Microsoft Dynamics 365 Business Central is an ERP tool that provides a consolidated way of managing sales, marketing, purchasing, inventory, manufacturing, and shipping logistics. Microsoft Dynamics 365 Business Central also contains a limited set of CRM tools for managing contacts, interactions, segments, opportunities, and marketing campaigns.
## Connections
To connect to a system, whether it is a source of data or the target where you are sending data, you must create a connection with that system’s required credentials. You typically connect to different systems within a flow and can reuse each connection every time you need to connect.
This system requires the following credential information for its connections: 

Connection Display Name
    
Enter a connection name that will help you remember the details of this connection. You can reuse connections multiple times in a single flow, and in more than one flow, and the credentials are hidden after you create the connection. Therefore, it’s helpful to provide a name that easily identifies this connection from others.
Only you can see the connection. Other users in your Composer app must create their own connections.
You must disable the admin consent workflow because Composer does not support it. 

Base URI
    
The parameter base URI, for example, `https://api.businesscentral.dynamics.com/v2.0/<tenantId>/<environmentname>/api/v2.0`. Each instance or tenant gets its own parameter base URI. 

Username
    
The OAuth username that you use to log into Microsoft Dynamics 365 Business Central. 

Password
    
The OAuth password that you use to log into Microsoft Dynamics 365 Business Central.
## Triggers
Each flow starts with either a _scheduler_ or a _trigger_. Schedulers are set to a default frequency of 15 minutes. Triggers, such as "each time a new record is created", are defined by you and provide multiple options related to the data in your system.
Triggers use a polling process to actively check for new updates from an external system. The polling frequency is 15 seconds.
This system provides the following trigger options: 

On New or Updated Sales Order
    
Checks for a new or updated sales order or a new or updated sales order line. Provide a value for **Company**. 

On New or Updated Item
    
Checks for a new or updated item. Provide a value for **Company**. 

On New or Updated Customer
    
Checks for a new or updated customer. Provide a value for **Company**.
### Polling Frequency
For triggers in this connector, the **Polling Frequency** field is required. This field enables you to select how often Composer makes a request to the underling system API to look for changes to records in active flows. You can select a different polling frequency for each flow in your organization. With a shorter frequency, the flow executes more often; however, a shorter frequency consumes more API calls. For example, if you have an order management flow, you might require nearly real-time updates, which can be achieved with a 15-second polling interval (which equates to 5760 API calls per day). In contrast, if your flow updates a pricing catalog, you could poll the flow every hour (which equates to 24 API calls per day).
## Actions
After you connect to a system and define the trigger or configure a scheduler, you define the actions that the flow performs. For example, you can copy a record between different systems, such as Workday and Salesforce. The actions you can perform depend on which system you are connected to.
This system provides the following actions: 

Create Sales Order
    
Create a single sales order and, if provided, a list of sales order lines. Provide a value for the following fields:
  * **Customer Number**



Update Sales Order
    
Update a single sales order and, if provided, a list of sales order lines. Provide a value for the following fields:
  * **Entity ID**



Get Sales Orders
    
Retrieve a filtered list of sales orders in addition to corresponding sales order lines. Provide a value for **Company**.

Create a single customer. Provide a value for **Company**. 

Update Customer
    
Update a single customer. Provide a value for the following fields:
  * **Entity ID**
