SQL API Endpoint

The PCR-360 API offers the ability to send a SELECT query to retrieve any data the system offers. It is important to note that this functionality is limited to only SELECT statements and no data can be modified (UPDATE statements) or destroyed (DELETE statements). Having the ability to SELECT any data that is required is a very powerful tool. This allows the API to be more flexible when retrieving data than any standard endpoint.

To use the SQL endpoint, make a POST request to the SQL endpoint using one of the three possible data formats (JSON, XML, or PHP). This may seem odd as retrieving data is usually done via a GET request, however, SQL statements can become quite long and, to avoid issues with URL maximum lengths, we have decided to utilize POST requests for this functionality.

Using POST Calls

Using POST Calls

• POST requests will ignore parameters supplied as a query string and need any additional parameters in the request Body.

• To configure the number of Pages/Results returned by the API (this is most useful for the SQL Endpoint), you can send these as additional Parameter's in the Body.

  Parameter	Data Type	Default	Description
  limit	Interger	20	Number of listings to show.
  page	Interger	1	Page number to show.

  
  

• API fields are not case sensitive, and will always be returned in the lower case format.

Below is the single parameter for making an SQL POST request.

Using the Data Dictionary

Please see the Data Dictionary for the structure of the database which will assist in creating queries.

The Data Dictionary can be used as an index to see what data might be related to other tables for ease in building up the SELECT and FROM portions of the statements you desire to build up. Specific data on identified fields can be further filtered in the WHERE portion of the statement.

Sample SQL Call

Call:

POST DOMAIN/KEY/sql.json

Classes of Service

Classes of Service values can be retrieved only through the SQL endpoint.  Retrieving these values is needed for using the Authentication Token Mode of the API.

Call:

POST DOMAIN/KEY/sql.json

Body:

Return:

{
    "status": "success",
    "page": 1,
    "count": 3,
    "total_count": "3",
    "results": [
        {
            "RECID": "1",
            "CODE": "0",
            "DESCRIPTION": "First Class"
        },
        {
            "RECID": "2",
            "CODE": "9",
            "DESCRIPTION": "Second Class"
