String Parameter in jquery ajax POST

Question

The Curl of the API says that this is the correct format:

curl -X POST --header "Content-Type: application/json" --header "Accept: application/json" -d "2018062703,2018062703" "http://XX.XX.XX/api/my_url"

This API need parameters like this:

I'm trying to send them with this code:

var data = "2018062703,2018062703";
$.ajax({
    type: 'POST',
    data: data,
    url: 'my/api/url',
    dataType: 'json',
    success: etc...

But I get a 404 not found. In the console of Chrome I got this:

What I'm doing wrong? In the web of the API when I put the parameters as a string "2018062703,2018062703" it works.

You get a 404 and it is saying your data is wrong? wouldn't it be a 5XX ? — epascarello

Yes, I know it's weird, but with the same URL of the API by Swagger works ok. — pmiranda

Look at the answer below and look at your swagger documentation. The parameter key is "filtro". — Taplar

your data type is json in ajax call and you are passing string. convert it to json and try — Akhil Aravind

Your data parameter in your AJAX call is invalid. It should look like this:

data: { filtro: data }

As it is now, you're trying to call your API with a parameter named 2018062703,2018062703 which has no value.

Now I have it in that way, but in Chrome console I got in Headers -> Form Data: filtro: 2018062703,2018062703 but still 404 not found. If I change to GET (only to force to have method error) I got ` GET h ttp : //XX.XX.XX/my_api/?filtro=2018062703%2C2018062703 405 (Method Not Allowed)` which is correct

A 404 most likely means the URL you're calling is wrong. If you're 100% sure the URL is correct, it might be a bit overkill but I would record the call from Swagger and the call you're making in AJAX with a tool like Fiddler and compare them. That way, you'll see exactly what's happening.

I tried with GET method in the ajax, if the URL wasn't correct I would get a 404 too, but instead I get the 405 Method Not Allowed wich is fine.

Finally I had to JSON.stringify() my data, plus, add the contentType: "application/json",``

I will pick you answer as the correct one because it leads me to rewrite my code.
