Difference between query parameters and URI parameters in MuleSoft
Query
parameters
·
Appended to the end of the endpoint URL, after a question mark
(?)
·
Typically used to pass optional parameters to an endpoint
·
Examples:
o /api/users?name=John&age=30
o /api/products?search=book&category=fiction
·
Accessed using the queryParam expression in MuleSoft
URI parameters
·
Embedded in the endpoint URL, surrounded by curly braces ({})
·
Typically used to pass required parameters to an endpoint
·
Examples:
o /api/users/{id}
o /api/products/{product_id}
·
Accessed using the pathParam expression in MuleSoft

When to use
query parameters
·
To pass optional parameters to an endpoint
·
To pass a large number of parameters to an endpoint
·
To make your code more readable and maintainable
When to use
URI parameters
·
To pass required parameters to an endpoint
·
To make your endpoint URL more specific and descriptive
·
To improve the performance of your API
Note: You can also use both query parameters and URI parameters in the same endpoint URL. For example:
GET
/api/users/{id}?name={name}
This endpoint URL accepts both
the id and name parameters. The id parameter is required, and the name
parameter is optional.
Conclusion
Query parameters and URI parameters are both powerful tools for passing data to API endpoints. The best way to decide which type of parameter to use is to consider the specific needs of your API.
