Hello, I am trying to integrate with PayPal as third party app inside my platform. I am using developer account and got my client key and secret, I followed the guides in the following links: List of scopes: https://developer.paypal.com/docs/log-in-with-paypal/integrate/reference/#scope-attributes Aouth to login: https://developer.paypal.com/docs/log-in-with-paypal/upgrade/ https://developer.paypal.com/docs/log-in-with-paypal/integrate/ The thing is the aouth link "https://www.sandbox.paypal.com/signin/authorize" responds with => StatusCodeError: 401 - {"error":"invalid_client","error_description":"Client Authentication failed"} .. Could anyone help me with this? Here is the authentication model I am using: scope : [ 'openid' , 'profile' , 'email' ], scopeDelimiter : ' ' , accountNameFromProfileInfo : context => { return context . profileInfo [ 'name' ] || context . profileInfo [ 'user_id' ]. toString (); }, authUrl : 'https://www.sandbox.paypal.com/signin/authorize' , // authUrl: context => { // return 'https://www.sandbox.paypal.com/signin/authorize?' + // `response_type=code&client_id=${context.clientId}` + // `&flowEntry=static` + // `&redirect_uri=${context.callbackUrl}` // }, requestAccessToken : context => { // don't put params into post body, won't work, have to be in query let tokenUrl = 'https://api-m.sandbox.paypal.com/v1/oauth2/token?' + 'grant_type=authorization_code&code=' + context . authorizationCode + '&redirect_uri=' + context . callbackUrl + '&client_id=' + context . clientId + '&client_secret=' + context . clientSecret ; return request ({ method : 'POST' , url : tokenUrl , headers : { 'Content-Type' : 'application/x-www-form-urlencoded' }, json : true }). then ( result => { console . log ( '[[[[[[[Token Result]]]]]]]:' , result ); profileInfo = result [ 'data' ]; let newDate = new Date (); newDate . setTime ( newDate . getTime () + ( result [ 'expires_in' ] * 1000 )); return { accessToken : result [ 'access_token' ], //refreshToken: result['refresh_token'], accessTokenExpDate : newDate }; }); }, I have tested the accessToken request through postman using my client key and secret, and it's generated successfully.
