Angular 19 . Paypal REST API - Request is not well-formed, syntactically incorrect, or...

Where i'm wrong??

payment.service.ts

autenticaService(): Observable<Object> {

const uri = '/v1/oauth2/token';
const data = 'grant_type=client_credentials';
let body = new URLSearchParams();
body.set('grant_type', 'client_credentials');

return this.httpClient.post(
`${this.endpoint_url}/v1/oauth2/token`, body ).pipe(
map(
data => {
return data;
}
))
}

createOrder = (): Observable<Object> => {

let order_data_json = {
'intent': 'CAPTURE',
'purchase_units': [{
'amount': {
'currency_code': 'EUR',
'value': '0.01'
}
}]
};

const data = JSON.stringify(order_data_json);

return this.httpClient.post(
`${this.endpoint_url}/v2/checkout/orders`, data, { headers }).pipe(
map(
data => {
console.log(data);
return data;
}
))
}


shopping-cart.ts

acquista = () => {
//https://www.paypal.com/ncp/payment/AB32BUFY4R824
this.paymentService.autenticaService().subscribe(
body => {
let authPaymentToken = this.paymentService.parseBearer(JSON.stringify(body));
this.cookieService.set("TokenKey", 'Bearer ..here i put the token..');
this.paymentService.createOrder().subscribe(
body => {
console.log(body);
let link = Object(body);
let prodotti: IArticoli[] = [];
this.ordine = {
idord: '000002',
idutente: '123Stezza',
idorganizzazione: 'mygroup',
listaProdotti: this.prodotti,
mailverificata: false,
pagamentoeseguito: false,
date: new Date(),
codStat: 'in attesa',
linkpagamento: link['links'][3]['href']
}

console.log(this.ordine);
this.ordiniService.insOrdine(this.ordine).subscribe({
next: (response) => {
console.log(response);
//window.location.href = link['links'][1]['href'];
this.paymentService.captureOrder(this.ordine.linkpagamento).subscribe({
next: (response) => {
console.log(response);
//window.location.href = link['links'][1]['href'];
},
error: (error) => {
console.log(error);
}
});
},
error: (error) => {
console.log(error);
}
});
}
)
});
}


interceptor


if (req.url.indexOf(`${environment.authPaypalUri}/v1/oauth2/token`) === 0) {
const auth = `${environment.client_id}:${environment.client_secret}`;
let authString = "Basic " + window.btoa(auth);

req = req.clone({
setHeaders: { 'Authorization': `${authString}` }
});
console.log(req);
return next.handle(req);
} else if (req.url.indexOf(`${environment.authPaypalUri}/v2/checkout/orders`) === 0) {
const auth = `${environment.client_id}:${environment.client_secret}`;
let authPaymentToken = this.cookieService.get("TokenKey");
req = req.clone({
setHeaders: { 'Content-Type': 'application/json; charset=utf-8', 'Authorization': `${authPaymentToken}`, 'Accept' : 'application/json', }
});
return next.handle(req);
}

I'm going crazy with this stuff.. how can i resolve? I think i'm putting everything ok.

I've followed this hints : https://developer.paypal.com/docs/api/orders/v2/#orders_get

I can get the token, sometimes, but the "createOrder()" method doesn't want to go over..
