Selecting and Defining the Data Connector File Source

Several connectors including JSON, MS Excel, SVG, Text, XML, MQTT, and Stream Simulator, allow selection from a File, Web URL, or Text source.


Select the connector file source:

q  File

You can either:

·         Upload a data source snapshot by clicking Upload File  then Browse  to browse to the file source.

After selecting the file, it is displayed with the timestamp of the snapshot.


The data source is placed in the repository and locked, synchronized, and bundled with the workbook version.

To change the data source, click  then Browse  to browse to a new version of the file, which is uploaded into the repository, and also create a new version of the workbook that reads it.

·         Link to a data source file by clicking Link to File  and entering a File Path.

Ensure that in a cluster, you need to use a a shared path, or put it on every node and use a path that resolves on every node. You can update its contents whenever you want.


q  Text

Then enter the text block to be parsed.



The Text file source is not available for the MS Excel connector.




q  Web URL

The dialog changes to allow specification of the following:




Authentication Type

·         Basic

Basic authentication.

·         OAuth

Then enter the following settings:

o    Token URL – The URL to retrieve the access token from.

o    Token Request Body – The request body used for access token requests.

o    Add Access Token To - The Access token retrieved from the Token URL can be added to headers, URL or request body, depending on how the endpoint needs the token.

§  Request Header - A header is automatically added to the REST API request.

§  Request URL - The URL needs to be manually parameterised with a {access_token} parameter, before calling the REST API, the parameter is replaced with the actual token.

§  Request Body - The Request Body needs to be manually parameterised with a {access_token} parameter, before calling the REST API, the parameter is replaced with the actual token.
