post - Uber API | Requesting Access Token for Ride request returns 'invalid_grant' error -

-

i want users request uber rides app.
https://developer.uber.com/docs/rides/authentication

under oauth 2.0 section @ above url, there 6 steps :
1. authorize (done)
2. receive redirect (done)
3. access token ('invalid_grant' error)

the following screenshot postman. tried passing client_id, client_secret, grant_type, redirect_uri , code params, form-data , x-www-form-url-encoded. everytime returns same error.

enter image description here

i have put 'http://localhost:3000/auth/uber/callback' redirect url in uber app dashboard.

i have tried following curl command in terminal,but returns same 'invalid_grant' error

enter image description here

can me issue.

your postman request looks correct me. best guesses @ whats going on:

1) have multiple redirects set up, , you're using 1 redirect url when authorization phase , different 1 when try , token exchange

2) you're doing authorization 1 client_id, , trying token exchange another

3) you're authorization code has been used / expired. keep in mind 1 request.

could try following , tell me happens:

1) authorization flow , pay special attention client id , redirect uri put in authorization url correct

2) after browser redirects, copy authorization code out of redirect url

3) put authorization code postman request / curl statement , make sure client id / redirect uri correct when it.

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
