A query string contains the value of the String data type entered by the user in a URL sent to the server.
Each query string comprises a key name and a value joined together using an equals sign (=).
There can be multiple query strings; two or more query strings are separated by ‘&.’
The pattern of the query string is: https://BaseURL/dataapi/Group_Name/API_Name?querystring1=value1&querystring2=value2 (See the green box in the image below)
The data values received in a request are retrieved through the Request variable. For example, to update the received value of the query string “Number1” into the variable “str,” select the source value as Variables>Request>querystrings>Number1.
Query strings are defined by:
Query Name: A query string must have a unique query string name and conforms to the variable name rules. This name will be used when reading the query string value in Actions.
URL Query Name: This field defines how the query string will be displayed in the URL. It can be the same as a query string name, or a different text can be assigned.
Documentation Data Type: This field defines the data type in the query string. E.g., In an API created and configured for the calculation of values entered by a user, the data type for the query string will be an integer. This detail is displayed in the API documentation.
Example for query string value: This field defines the sample value for this query string to be displayed in the documentation.
Parameter Description: This field explains the purpose of the query string. This text is visible in the API documentation.
Required: To define that the value for a query string must exist when the request is received, select the “Required” field.
If this value is missing, an error will be returned to the caller on calling the API. (In the image below, a value for the query string “Number2” is required.)
