How to refresh an expired accessToken ?

[vivinRajagopalan]

Hi,

Currently when we are trying to refresh the expired access token we have to use the refresh token as grant type . There are situations when my refresh token has expired (guess this has something to with 5 connections to a connected app in salesforce) and in this scenario how would i get an access token back ?

should the user start from the beginning where he requests an auth code and establish a connection from there ?

Please let me know. Thanks in advance !

When you expire the "refresh token", they should do so.

Hi stomata ,
Thanks for the reply. But I don't expire the refresh token. Sales force
does it and when salesforce expires the refresh token even if I try
refreshing the token using grant type equal to refresh token does not work
as it has already expired.

Please find below the steps i tried :

1)create a connection object in my code :

  var conn = new jsforce.Connection({
      oauth2: oauth2,
      accessToken: accessToken,
      refreshToken: refreshToken,
      instanceUrl: instanceURL,
      id: id
  });

2. trying to search a lead/contact in sales force

conn.search(searchQuery,function(err, response) {
//some logic
}

3. Now i get an err in the callback saying "expired access/refresh token"

4. In my case the refresh token has expired.

In this scenario i have tried,

oauth2.refreshToken(refreshToken,function(err, ret) {
//i tired create a new connection
}

This did not work as it was not even returning anything.........

Then i tried

Conn.on(refresh) too and i too did not work. Please let me know your thoughts

@vivinRajagopalan It doesn't matter who expired the refresh token. The expired refresh token is not useful and you need to ask authorization again by oauth2 flow.

Thanks a lot @stomita

what is the default lifetime of refresh tokens in Salesforce? Mine seems to be expiring after about 1 day (this seems short). Is it possible to increase this time?
