CAD Partner Interoperability

The Post API for Ambulance CAD Data is used to update ambulance data in EMResource. This data is communicated using a JSON for REST web service.

With this API, EMResource receives ambulance data from a CAD system and aggregates the data to display the following information in EMResource.

1. Facility Information.

   1. Number of ambulances that have arrived at each facility.

   2. Number of ambulances enroute to each facility.

   3. Average wait time of ambulances that have arrived at the facility to offload patients.

   4. Maximum wait time of an ambulance that has arrived at the facility to offload patients

2. EMS Agency Information.

   1. Number of ambulances that have arrived at facilities.

   2. Number of ambulances en route to facilities.

   3. Number of available ambulances.

Values

Example

The example below describes the various messages that are sent to EMResource.

For an example Postman file, contact Juvare.

The Helicopter CAD Interface is available for Juvare’s clients that want to manage helicopter and other emergency vehicle statuses in EMResource. The interface uses a web service to communicate with the client’s CAD system, sending and receiving messages in XML format.

XML

To send a message using XML, the following information must be specified in your message.

Authorization

Basic Auth: Username and Password to be provided in a separate document

Headers

Content-Type: text/xml

Address

https://emresource.juvare.com/partnergateway/PartnerEndpoint

HTTP Method: POST

Header (Example)

                <?xml version="1.0" encoding="utf-8"?>
                <requestDefinition actionName='your action name' systemName='EMRESOURCE'
                divisionName='your division name'>
                </requestDefinition>
                    

Body (Example)

                <resourceStatus>
                    <resource>
                        <resourceId>your resource ID</resourceId>
                        <name>your resource name</name>
                        <location>
                            <latitude>33.177238</latitude>
                            <longitude>-96.596908</longitude>
                        </location>
                        <availability>
                            <code>3001000</code>
                            <label>Available</label>
                            <commentText>testing</commentText>
                        </availability>
                        <lastUpdateTime>2022-04-15T14:47:00</lastUpdateTime>
                    </resource>
                </resourceStatus>
                    

Values

Example

For an example Postman file, contact Juvare.

When sending data through a POST API, you can log into EMResource to verify the information was received. To do this:

1. Request a UI username and password from Juvare.

2. Go to EMResource and log in with the UI credentials.

3. Verify that the information is displaying correctly.

If you receive a message when you submit the API, locate it in the examples below and attempt to resolve the issue. If you need assistance, contact Juvare.

Response includes Status Failures

In the example below, it states there were 744 status failures even though it is likely everything was sent successfully.

                <p><resourceFailures>0</resourceFailures></p>
                <p><resourceSuccesses>9</resourceSuccesses></p>
                <p><statusFailures>744</statusFailures></p>
                <p><statusSuccesses>363</statusSuccesses></p>
                    

This typically happens when numeric status types are updated through the API but the updated value is the same as the previous value. In this case, EMResource displays the new timestamp from your message and the value remains as it was before.

Typically, there is not an issue unless a true error message is received. These can be found in the error tag of the response message.

Error Message: SOAP-ENV:ServerEMSystem is unable to process this request

There are two possible reasons for this error:

• The web service username and password contains a forbidden special character.

• More than one of the same Standard Status Type is used in the region.

If you receive this message, contact Juvare.

Error Message: SOAP-ENV:ServerUser is not authorized for the target

This message likely appears because the web service user is not listed in the interface. If you receive this message, contact Juvare.

Error Message: Please specify a username and password following the HTTP Basic Authentication

The URL listed in your message is likely pointing to the wrong address. If you receive this message, contact Juvare to verify the URL.

Error Message: User May Not Update Status

There are two possible reasons for this error:

• The status type is not currently being queried by the region (for example, it is an event only status type).

• The status type is being queried by the region, but the event does not include that resource.

If you receive this message, contact Juvare.

Your web service username and password can be used to access the EMResource Interface Summary, which includes the following information:

• Action Name

• Division Name (also known as the Interface Key)

• Address or URL

• Participating Resources and corresponding IDs

• Status Names

• Multiple choice options for multichoice statuses

To access the Interface Summary

Go to EMResource and log in using the web service username and password provided by Juvare.

1. On the upper left, in the main menu, select Setup then select Interface Dashboard.

2. For interface, select Summary.

3. Review the interface information on this page and as needed, update the details.
