  • Статья

 

Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online

This group of samples demonstrate how to perform basic CRUD (Create, Retrieve, Update, and Delete) and associative operations using the Microsoft Dynamics 365 Web API. This sample is implemented as a separate project for the following languages:

This topic describes a common set of operations implemented by each sample in this group. This topic describes the HTTP requests and responses and text output that each sample in this group will perform without the language specific details. See the language specific descriptions and the individual samples for details about how these operations are performed.

Note

For brevity, less pertinent HTTP headers have been omitted. The URLs of the records will vary with the base organization address and the ID of the record assigned by your Dynamics 365 server.

Section 1: Basic create and update operations

This section creates a single contact then performs a series of updates upon that instance. Note that the response header OData-EntityId contains the URL to this newly created record (entity instance), which parenthetically includes the unique ID for this record.

  1. Create a new contact, named Peter Cambel.

    HTTP Request

    POST http://[Organization URI]/api/data/v8.2/contacts HTTP/1.1
Content-Type: application/json
OData-MaxVersion: 4.0
OData-Version: 4.0
{
  "firstname": "Peter",
  "lastname": "Cambel"
}

    HTTP Response

    HTTP/1.1 204 No Content
OData-Version: 4.0
OData-EntityId: http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03)

    Console output

    Contact 'Peter Cambel' created.

    The properties available for each type are defined within the metadata document and are also documented for each type in the Web API EntityType Reference section. For more general information, see Web API types and operations.

  2. Update the contact with values for annual income ($80,000) and job title (Junior Developer).

    HTTP Request

    PATCH http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03) HTTP/1.1
Content-Type: application/json
OData-MaxVersion: 4.0
OData-Version: 4.0
{
  "annualincome": 80000,
  "jobtitle": "Junior Developer"
}

    HTTP Response

    HTTP/1.1 204 No Content

    Console output

    Contact 'Peter Cambel' updated with job title and annual income.

  3. Retrieve the contact with its set of explicitly initialized properties. The fullname is a read-only property that is calculated from the firstname and lastname properties, which were explicitly initialized when the instance was created. In contrast, the description property was not explicitly initialized, so it retains its default value, a null string.

    Note that the response, in addition to the requested values and typical headers, also automatically returns the following types of additional information:

    • The primary ID for the current entity type, here contactid.

    • An ETag value, denoted by the @odata.etag key, which identifies the specific version of the resource requested. For more information, see Perform conditional operations using the Web API.

    • The metadata context, denoted by the @odata.context key, provides a way to compare query results to determine if they came from the same query.

    • A _transactioncurrencyid_value that indicates the local currency of the monetary transaction.

    HTTP Request

    GET http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03)?$select=fullname,annualincome,jobtitle,description HTTP/1.1

        Income: 80000
        Job title: Junior Developer
        Description: .

    Important

    You should always use selection and filtering in retrieval operations to optimize performance. For more information, see Query Data using the Web API.

  4. Update the contact entity instance by supplying new values to these same properties.

    HTTP Request

    PATCH http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03) HTTP/1.1

OData-Version: 4.0
{
  "jobtitle": "Senior Developer",
  "annualincome": 95000,
  "description": "Assignment to-be-determined"
}

    HTTP Response

    HTTP/1.1 204 No Content

    Console output

    Contact 'Peter Cambel' updated:
        Job title: Senior Developer
        Annual income: 95000
        Description: Assignment to-be-determined

    Important

    Only send changed properties in update requests. For more information, see Basic update.

  5. Explicitly set a single property, the primary phone number. Note this is a PUT request and that the JSON key named value is used when performing operations on individual properties.

    HTTP Request

    PUT http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03)/telephone1 HTTP/1.1

OData-MaxVersion: 4.0
OData-Version: 4.0
{
  "value": "555-0105"
}

    HTTP Response

    HTTP/1.1 204 No Content

    Console output

    Contact 'Peter Cambel' phone number updated.

  6. Retrieve that same single property, the primary phone number. Again note the use of the key named value.

    HTTP Request

    GET http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03)/telephone1 HTTP/1.1

   "value":"555-0105"
}

    Console output

    Contact's telephone# is: 555-0105.

  7. Create a similar contact but also return instance information in the same operation. This latter capability is enabled by the Prefer: return=representation header. This capability was introduced with the December 2016 update for Dynamics 365 (online and on-premises) and requires version 8.2 or higher.

    HTTP Request

    POST http://[Organization URI]/api/data/v8.2/contacts?$select=fullname,annualincome,jobtitle,contactid HTTP/1.1

        Annual income: 80000
        Job title: Junior Developer
Contact URI: http://[Organization URI]/api/data/v8.2/contacts(199250b7-6cbe-e611-80f7-00155da84c08)

  8. Update this similar contact and also return instance information in the same operation. Again, this capability is enabled by the Prefer: return=representation header. This capability was introduced with the December 2016 update for Dynamics 365 (online and on-premises) and requires version 8.2 or higher.

    HTTP Request

    POST http://[Organization URI]/api/data/v8.2/contacts?$select=fullname,annualincome,jobtitle,contactid HTTP/1.1

        Annual income: 95000
        Job title: Senior Developer

Section 2: Create with association

This section creates a new account instance named Contoso, Ltd. and associates it to an existing contact, Peter Cambel, which was created in Section 1: Basic create and update operations. This creation and association is performed in a single POST operation.

  1. Create the Contoso, Ltd. account and set its primary contact attribute to the existing contact Peter Cambel. The @odata.bind annotation indicates that an association is being created, here binding the primarycontactid single-valued navigation property to an existing contact, Peter Cambel.

    HTTP Request

    POST http://[Organization URI]/api/data/v8.2/accounts HTTP/1.1
Content-Type: application/json
OData-MaxVersion: 4.0

    Console output

    Account 'Contoso Inc' created.

  2. Retrieve the primary contact for the account Contoso, Ltd., again using $expand with the primarycontactid single-valued navigation property to access the associated contact EntityType record.

    HTTP Request

    GET http://[Organization URI]/api/data/v8.2/accounts(65f77a42-5f0e-e611-80e0-00155da84c03)?$select=name,&$expand=primarycontactid($select=fullname,jobtitle,annualincome) HTTP/1.1

      "contactid":"60f77a42-5f0e-e611-80e0-00155da84c03"
   }
}

    Console output

    Account 'Contoso Inc' has primary contact 'Peter Cambel':
     Job title: Senior Developer
     Income: 95000

This section demonstrates how to create an entity instance and related entity instances, in a single POST request. Using this method, all instances are newly created; there are no existing instances to associate with. This approach has two advantages. It is more efficient, replacing multiple simpler creation and association operations with one combined operation. Also, it is atomic, where either the entire operation succeeds and all the related objects are created, or the operation fails and none are created.

This section creates an account, its primary contact, and a set of tasks for that contact in one request.

  1. Create the account Fourth Coffee and its primary contact Susie Curtis and her three related tasks in one operation. Note the use of the single-valued primarycontactid navigation property and the collection-valued navigation property Contact_Tasks to define these relationships, respectively. Single-valued navigational properties take an object value, whereas collection-valued navigation properties take an array value.

Section 4: Associate and disassociate existing entities

This section demonstrates how to associate and disassociate existing entity instances. Forming an association requires the use of a reference URI and relationship object, which are then sent in a POST request. Disassociating requires sending a DELETE request to the reference URI for that association. First a one-to-many association is formed between a contact and an account. Then a many-to-many association is formed between a competitor and one or more opportunities.

  1. Add Peter Cambel as a contact to the account Fourth Coffee using the contact_customer_accounts collection-valued navigation property. Note the use of the special key @odata.id to specify the associated record.

    HTTP Request

}

    HTTP Response

    HTTP/1.1 204 No Content

    Console output

Section 5: Delete entities (sample cleanup)

This section demonstrates how to delete entity instances. The corresponding message is a straightforward DELETE request that uses the URI of the entity instance to be deleted. If the target entity has a parent-child relationship with other entities, then deleting the parent will, by default, automatically cascade delete child instances. For example, in this sample, tasks have contact as their parent. For more information, see Entity relationship behavior.

  1. Each element of the collection of entity URLs is deleted. The first is a contact record for Peter Cambel.

    HTTP Request

    DELETE http://[Organization URI]/api/data/v8.2/contacts(60f77a42-5f0e-e611-80e0-00155da84c03) HTTP/1.1
Content-Type: application/json
OData-MaxVersion: 4.0
OData-Version: 4.0

    HTTP Response

    HTTP/1.1 204 No Content
