Add Request Query String Parameters
How to add request query string Parameters to my Azure API operation to make it more user friendly?
If your API operation uses URL template parameters, the client system must call it with parameter values specified in the correct position, like:
The above URL is nice and short. But it confuses users: Is the rate for from USD to EUR or from EUR to UDS?
To avoid he confusion, you change the URL signature to use query string parameters, like
One big advantage of query string parameters is that their position order is not important. So the following 3 URL are identical:
https://.../exchange-rate?from=USD&to=EUR&date=2020-10-10 https://.../exchange-rate?to=EUR&date=2020-10-10&from=USD https://.../exchange-rate?date=2020-10-10&from=USD&to=EUR
Here are steps to create template parameters:
1. Go to the publisher portal of the API Management Service.
2. Open the "First API" and add a new operation "Get exchange rate #2".
3. Enter the following to create the operation:
HTTP verb: GET URL template: /exchange-rate Rewrite URL template: /currency-exchange Display name: Get Exchange Rate #2
4. Click "Parameters" on the left. You see parameter fields displayed.
5. Click "ADD QUERY PARAMETER" repeatedly to enter 3 parameters:
NAME DESCRIPTION TYPE VALUES REQUIRED from From-currency code string USD x to To-currency code string EUR x date From-currency code string 2020-10-10 x
