redirect()->route laravel return html not go to function

I need to build a personaliced response to get one URL returned from API. In my function store i´m saving all data in my db ok. I have a personaliced class that this class have any method to connect API and return response, etc. In my function store, i have this call:

return redirect()->route('commercialautograph.precontract', ['precontract' => $precontract]);

This call return response from API:

$response = $this->client->request('POST', $url, [
            'auth' => [config("viafirma.apiKey.username"), config("viafirma.apiKey.password")],
            'json' => $json
        ]);
                        
        return $response;

if i build mehtod in my controller to get link from API, return BASE64´s pdf that i i´m sending to API. that's why i´m building redirect to other route, to close other operations. But my problem it´s that when i´m doing redirect, laravel returned me HTML:

{data: '<!DOCTYPE html>\r\n    <html lang="en">\r\n        <he…\n\r\n        </div>\r\n        \r\n    </body>\r\n</html>', status: 200, statusText: 'OK', headers: {…}, config: {…}, …}

This example it´s a webrowser console.

My route is:

Route::prefix('commercial')->name('commercial')->group(function(){
  Route::get('autograph/{precontract}', [CommercialPreContractController::class, 'autograph'])->name('autograph.precontract');
}

this route call other function in my same controller, that in this moment i want to arrive to function:

/**
     * Function to digital signature precontract
     */
    public function autograph(Array $precontract)
    {
        echo "llego¿?";
        exit();
        try{

I haven´t got any problem in logs.. And i don´t know that i´m doing wrong, but i can´t arrive to my function. I can´t to do $this->autograph beacause i need return response from API and read it in VUE js

I hope that anybody can help me.

Sorry for my bad english and thanks you very much for readme.

route list:

GET|HEAD        commercial/autograph/{precontract} commercialautograph.precontract › Commercial\CommercialPreContractCont…

Solution

You cannot send array of data as path parameters, it will not be mapped to any route. This will not work with any route method POST, GET, etc.

Remove {precontact} from path param, give it a static name e.g. commercial/autograph/precontact so this will be a static route. Send to that endpoint specific query (GET) parameters e.g. id, name ?id=...&name=... etc.

Also public function autograph(Array $precontract) does not work for any kind of data. Array $precontract is invalid for controllers in Laravel. It should be replaced with public function autograph(Request $request) see laravel docs. From there get the params like $request->input('id').

So after all these the redirect command will be

return redirect()->route('commercialautograph.precontract', ['id' => $precontract['id'], 'name' => $precontract['name']);
