VisualVault REST API Data Query Syntax

Search for specific API Results

HTTP endpoints (where noted) support the q={query} query string parameter which may be used to filter results.

Query Syntax

  • and
  • or
Comparison Operators
  • eq (equal)
  • ne (not equal)
  • gt (greater than)
  • ge (greater than or equal)
  • lt (less than)
  • le (less than or equal)

Set Operators

  • substring(value,start index, length) (substring function)


Query syntax requirements: Query string parameter must be URL encoded

  • Field names must be enclosed in square brackets
  • Search criteria must be enclosed in single quotes
Example: Filter form data where from field [invoice no] = '12345'
syntax without URL encoding: q=[invoice no] eq '12345'
with URL encoding: q=%5Binvoice%20no%5D%20eq%20'12345'

Using the query string parameter

In this example we will make a request using the FormTemplates endpoint. Normally with this request without the query string parameter, the results will be a complete list of all Form Templates (see here). We will append the query string parameter to the end of the request URL and search for a template where 'name = Purchase Requisition - Template'. We will make sure the query string is url encoded as follows. Use %20 for spaces and %27 for single quotes.

curl -X GET  \
     -H "Content-Type: application/json"   \
     -H "Authorization: Bearer $AccessToken" \{customerAlias}/{databaseAlias}/formtemplates/?q=name%20eq%20%27Purchase%20Requisition%20-%20Template%27

The following is returned
  "meta": {
    "status": 200,
    "statusMsg": "OK",
    "method": "GET",
    "href": "{customerAlias}/{databaseAlias}/formtemplates/?q=name eq 'Purchase Requisition - Template'"
