h3. Enabling the Javascript API

The Javascript API is enabled on all new installations of Yellowfin, form version 5.1 onwards. If you have upgraded from an older version, contact [Yellowfin Support|mailto:support@yellowfin.bi] for instructions on enabling the API for your installation.


h3. Using the Javascript API

There are two ways to load a report or dashboard on your HTML page. The simple method involves including a single Javascript URL. The more advanced method allows you to customise the report or dashboard display and load content on demand from other scripts.


h4. Basic Use

Include a script tag in your HTML page that points to your Yellowfin server. The report or dashboard identifier must be included as a parameter on the URL. For example:

{code:html}
<!-- report example -->
<script type="text/javascript" src="http://reporting.example.com/JsAPI?reportUUID=e5e5aaf3-c3b8-4f9b-8280-e21e4d848e63"></script>

<!-- dashboard example -->
<script type="text/javascript" src="http://reporting.example.com/JsAPI?dashUUID=3b0b6c9a-9dfb-41f0-b85a-eb17bb8aeeb9"></script>
{code}

The URL to the API is based on the URL used to access the Yellowfin front-end. For example, if users access Yellowfin through *[http://reporting.example.com:8080/\*|http://reporting.example.com:8080/*] then the Javascript API URL will be *[http://reporting.example.com/8080/JsAPI\*|http://reporting.example.com/8080/JsAPI*]. The URL will be accessed by the end user's browser, so it must be accessible from anywhere that end users will user your page (internal network, external, via VPN, etc.).

To ensure the server supports the version of the API your page is written for, you can use the {{version}} parameter. If the server supports multiple versions of the API, this parameter determines which version the server will use. If the server does not support the requested version, an error message will be displayed.  

{code:html}
<script src="http://localhost/JsAPI?version=2.1&reportUUID=e5e5aaf3-c3b8-4f9b-8280-e21e4d848e63" type="text/javascript"></script>
{code}

If the {{version}} parameter is not included, the server will use its current version.

h2. Report URL Parameters
{styleclass: Class=topLink}[top|#top]
{styleclass}
A report is identified by the {{reportUUID}} parameter. For backwards compatibility, it may alternatively be identified by the {{reportId}} or {{wsName}} parameters. Additional parameters may also be added to the URL, which will alter the way the report is displayed. The available parameters are:

h3. {expand:title=Expand here...}
|| Parameter || Description ||| |{{reportUUID}} | Either {{reportUUID}}, {{reportId}} or {{wsName}} must be present.
The unique ID identifying the dashboard to load. || |{{reportId}} | Either {{reportUUID}}, {{reportId}} or {{wsName}} must be present.
The numeric reportId identifying the report to load. It is recommended to use the {{reportUUID}} parameter instead. || |{{wsName}} | Either {{reportUUID}}, {{reportId}} or {{wsName}} must be present.
The Web Service name identifying the report to load. It is recommended to use the {{reportUUID}} parameter instead. || |{{version}} | The API version to use. If the server does not support the requested version, an error message will be displayed. If this is not included, the server will use its current API version. || |{{elementId}} | The id of the html element in which to load the report. If this is not included, a container element will be created at the point that the script tag is included. || |{{showTitle}} | Default: {{true{}}}
Set to {{false}} to omit the title bar at the top of the report. All interactive buttons included in the title bar will also be omitted. || |{{showInfo}} | Default: {{true{}}
}Set to {{false}} to omit the Info button in the title bar. || |{{showFilters}} | Default: {{true{}}

Set to {{false}} to omit the previous page/next page button in the title bar (for reports with multiple pages). || |{{showExport}} | Default: {{true{}}
}Set to {{false}} to omit the Export button in the title bar. || |{{height}} | Set this to a numeric value to override the report height. || |{{width}} | Set this to a numeric value to override the report width. || |{{display}} | Default: {{chart{}}}

Set to {{chart}} to display the report initially as a chart.
This is ignored for reports that do not have both table and chart available. || |{{fitTableWidth}} | Default: {{true{}}}
Set to {{true}} to attempt to scale the report to the width of the enclosing element. || |{{canChangeDisplay}} | Default: {{true{}}}
Set to {{false}} to omit the buttons that allow the user to switch between chart and table display. || |{{username}} | Set this along with the {{password}} parameter to authenticate as a particular user when loading the report. This avoids the need for users to enter their login details before viewing restricted reports. || |{{password}} | Set this along with the {{username}} parameter to authenticate as a particular user when loading the report. || |{{token}} | Use a web service token to authenticate a user when loading the report. |

h3. Examples

This example includes a report and sets the dimensions of the report:
{code:html}
<script src="http://localhost/JsAPI?reportUUID=e5e5aaf3-c3b8-4f9b-8280-e21e4d848e63&width=500&height=350" type="text/javascript"></script>
{code}

This example uses an existing element to display the report in, and passes the user credentials:
{code:html}
<div id="myReportDiv" style="background: blue; width: 500px; height: 350px">
<script src="http://localhost/JsAPI?reportUUID=e5e5aaf3-c3b8-4f9b-8280-e21e4d848e63&elementId=myReportDiv&username=admin@yellowfin.com.au&password=test" type="text/javascript"></script>
</div>
{code}

This example uses an existing element to display the report in, overrides the report dimensions, and changes some of the initial display options:
{code:html}
<div id="myReportDiv" style="background: blue; width: 500px; height: 350px">
<script src="http://localhost/JsAPI?reportUUID=e5e5aaf3-c3b8-4f9b-8280-e21e4d848e63&elementId=myReportDiv&width=400&height=300&showFilters=false&display=table" type="text/javascript"></script>
