Can't get my URL parameters to match my API call to postgres

Question

I'm using postgrest as an API wrapper to my postgres db. The api reads my database schema and creates URL using common characters in the address.

I have a function like so = create function api.dividend(p_stocks text[])

A general API call:

/url?key=val;key2=val2

My API call for function create function api.dividend(p_stocks text[]):

/dividend?p_stocks=AAPL

In this case to test things out, I used AAPL as the input parameter. However this is the error I'm getting:

function api.dividend(p_stock => text) does not exist

As you see the return error is expecting this function, api.dividend(p_stock => text) However I tried creating a function using those parameters and I dont think its possible...

I would greatly appreciate some advice or suggestions on what suggestions I should try?

This isn't a schema problem because I've checked if the function is in the appropriate schema.

Here is the full function from postgres, if this helps:

create function dividend(p_stocks text[])
    returns table(symbol char, next_dividend_date date, ex_dividend_date date) 
as $$
    select distinct on (symbol) symbol, next_dividend_date, ex_dividend_date
    from api.security_stats 
    where api.security_stats.symbol = any($1)
    order by symbol, date desc 
$$ language sql;

I managed to solve the issue with the help of @Adrian,

/dividend?p_stocks=%7BAAPL%7D

This would be the correct URL path for postgrest to use the function/parameter. %7b = { , and %7D = }

Now the URL has the correct array format for my function.
