Question

limit the output

i use integration to get country , state , District name with using pincode ,

i use read only grid to display result but i want only 1 row result how can i do that ?

you can use pageSize parameter in read only Grid (gridfield) Function to limit the number of rows.

If the API supports this, then you should pass it in the API so you only get the desired result and you do not end up increasing your data size.

how can we know that API support this and how to configure if its support

you can go the documentation and can search for parameters
