REST API:bulk Resource

Provides Data Import capabilities using the REST API. Using this API, a CSV file containing data records can be uploaded to an object.

• REST Conventions and Considerations

See also:

• REST bulk record Resource

Requirements

• A valid Login session.
• A sessionId for the request header.
• A Mapping Profile, which maps CSV fields to record fields and specifies the Data Merge strategy, created either in the GUI, or using the import Mapping Profile Resource

Bulk Upload Object Data

Loads CSV data into an object.

Method

POST

URI

https://{yourDomain}/networking/rest/bulk/{objectName}

Parameter

objectName: An Object Identifier. Object names are recommended, but Object IDs are supported for backward compatibility.

All Custom Objects support bulk upload.

Note: Specify the Object Name in the URI. Case is significant.

Request

A multipart request with file part for the CSV data and an XML part with information.

Here's a sample request that uploads data to a Customers object:

Content-Type: multipart/form-data; boundary=.............................103832778631715

--.............................103832778631715
Content-Disposition: form-data; name="bulk";
Content-Type: application/xml;

<platform>
    <bulk>
        <mapping>CustomerMap</mapping>
    </bulk>
</platform>

.............................103832778631715
Content-Disposition: form-data; name="Customers.csv"; filename="Customers.csv"
Content-type: application/octet-stream

{contents of file}
.............................103832778631715--

Response

Returns the id of the submitted import job, along with a message telling whether or not the job was accepted for processing. (Use the REST import Status resource to follow the progress of the job.)

<platform>
    <message>
        <code>0</code>
        <description>Success</description>
        <id>yur456poi967</id>      <!-- import process job ID -->  
    </message>
</platform>

Fields

Name	Type	Required	Description
mapping	String	Yes	Name of the Mapping Profile created in the platform UI

Sample Http Client for bulk uploads

This sample client uploads Customer data. It is contained in the Samples Zip file.
(For the JAR files it uses, see Setting Up the Development Enviroment.)
