CData REST RSD – How to Pass Dynamic Bearer Token and Parse JSON Array Response with jsonproviderGet

Hi,

I’m creating a custom CData REST RSD for the Cynet API and consuming it through Incorta.

The RSD performs two calls: first a POST to obtain the access token, then a GET to the Alerts endpoint using the Bearer token.

The login works and the token is populated (length is 857 characters). I also confirmed that httpGet retrieves the raw response body from the Alerts endpoint. However, jsonproviderGet returns 0 rows.

The response from the Alerts endpoint is structured like:

{
"SyncTimeUtc": "2026-09-28T06:28:02.0628506Z",
"Entities": [
{
"ClientDbId": 166,
"Uniqueness": "...",
"IncidentName": "Host Was Not Scanned",
"IncidentDescription": "..."
}
]
}

Here is the relevant RSD:

<api:script xmlns:api="http://apiscript.com/ns?v1"
xmlns:xs="http://www.w3.org/2001/XMLSchema">

<api:info title="CynetAlerts"
desc="Cynet alerts - rolling last 30 days"
xmlns:other="http://apiscript.com/ns?v1">

<attr name="ClientDbId"
xs:type="long"
columnsize="20"
readonly="true"
other:xPath="/json/Entities/ClientDbId" />

<attr name="Uniqueness"
xs:type="string"
columnsize="2000"
readonly="true"
other:xPath="/json/Entities/Uniqueness" />

<!-- additional attributes -->

</api:info>

<!-- Login configuration -->

<api:set attr="loginin.DataModel" value="DOCUMENT" />
<api:set attr="loginin.ConnectionType" value="HTTPS" />
<api:set attr="loginin.URI" value="access_token_uri" />
<api:set attr="loginin.AuthScheme" value="NONE" />
<api:set attr="loginin.ContentType" value="application/json" />
<api:set attr="loginin.EncodePostData" value="false" />
<api:set attr="loginin.XPath" value="/json" />
<api:set attr="loginin.ElementMapPath#1" value="/json/access" />
<api:set attr="loginin.ElementMapName#1" value="access" />

<api:set attr="loginin.data">
{
"accessKey": "XXXXX",
"secretKey": "XXXXX"
}
</api:set>

<api:set attr="tmp.token" value="" />
<api:set attr="loginin.method" value="POST" />

<api:call op="jsonproviderGet" in="loginin" out="loginout">
<api:set attr="tmp.token" value="[loginout.access]" />
</api:call>

<!-- Alerts -->

<api:set attr="alertsin.DataModel" value="DOCUMENT" />
<api:set attr="alertsin.ConnectionType" value="HTTPS" />
<api:set attr="alertsin.URI"
value="base_uri?LastSeen=2026-09-26%2000:00:00" />
<api:set attr="alertsin.JSONPath" value="$.Entities" />
<api:set attr="alertsin.method" value="GET" />

<api:set attr="alertsin.Header:Name#1" value="Authorization" />
<api:set attr="alertsin.Header:Value#1"
value="Bearer [tmp.token]" />

<api:set attr="alertsin.Header:Name#2" value="client_id" />
<api:set attr="alertsin.Header:Value#2" value="XXXXX" />

<api:call op="jsonproviderGet" in="alertsin" out="alertsout">
<api:push />
</api:call>

</api:script>

Could someone advise what is causing jsonproviderGet to return zero rows?

Specifically, I would like to confirm:

  • Is alertsin.JSONPath = "$.Entities" correct when Entities is an array?

  • Should the other:xPath values be /json/Entities/ClientDbId, etc., or should they be relative to each entity?

  • Should api:push explicitly reference alertsout?

  • Is using in="alertsin" with jsonproviderGet correct in this structure?

The HTTP GET itself is successful; the issue appears to be the JSON parsing/row generation.

Thanks.

Hi ​@stalha.tariq,


I am not seeing any issues with the Alert block so that should be good. For the authentication block, it can be simplified further to get down to a cleaner script but other than that it does look functional. The main issue is the XPath has not been defined correctly. Because for the JSONPath repeat element, that wildcard is *, whereas the wildcard is % for the column other:xPath values. Can you try making the changes below?

<api:info title="CynetAlerts" desc="Cynet alerts - rolling last 30 days" xmlns:other="http://apiscript.com/ns?v1">

<attr name="ClientDbId" xs:type="int" columnsize="4" precision="11" readonly="false" other:xPath="/json/%/ClientDbId" />
<attr name="IncidentDescription" xs:type="string" columnsize="2000" readonly="false" other:xPath="/json/%/IncidentDescription" />
<attr name="IncidentName" xs:type="string" columnsize="2000" readonly="false" other:xPath="/json/%/IncidentName" />
<attr name="Uniqueness" xs:type="string" columnsize="2000" readonly="false" other:xPath="/json/%/Uniqueness" />

</api:info>

The JSONPath for the Alerts block can be set as below:

<api:set attr="JSONPath" value="$.%" />

Also, you should indeed include the api:push item="alertsout"

 <!-- Fetch the target data -->
 <api:call op="jsonproviderGet" in="alertsin" out="alertsout">
      <api:push item="alertsout" />
  </api:call>

Kindly give this a try and let me know if this resolves the issue.
