I'm following this (Bulk Api) Trailhead, I have valid SessionId and when I try to authenticate I'm getting the following error:

I have created few records using the same SessionId and I know its a valid SessionId and I'm not sure what else is the issue here.


> exceptionCode: InvalidSessionId  
> exceptionMessage: Unable to find session id

  • It sounds like you may have gotten logged out of your Org while in Workbench. Otherwise, once you have a jobId, you can use the same jobId to add as many batches to it as you want but the url needs to be at /services/async/apiversion/job/jobId/batch. You can also query the status of the job or close the job if you have the jobid.

  • I'm experiencing the same issue in Workbench. I haven't logged out of my org, but I still receive the same error message about the session ID. I attempted to log all the way out, and log in again, but to no avail. I even used 3 different browsers, but no luck. Mar 17, 2017 at 16:08
  • Did this error resolved? I do get this error even after trying the way @suresh mentioned

  • I'm not sure what I did but after couple of days I able to complete the trailhead, I'm thinking maybe you need to clear your cache and restart your computer and try?

  • one thing worth noting is that the URL actually needs to be 37 instead of v37... It's different from the services/data/ versioning for some reason

Thanks Suresh


Instead of passing token, try passing running user sessionId in 'X-SFDC-Session'. It worked for me.

System.debug(UserInfo.getOrganizationId().substring(0, 15) + '***' + UserInfo.getSessionId().substring(15));

your sessionId is after the *** just to differentiate from OrgId to sessionId
