Support » Plugin: Object Sync for Salesforce » Error 400: invalid client credentials

  • Resolved James Roberts



    I’m trying to connect/authenticate SalesForce. I’ve followed the steps here, and when I click the “Connect To SalesForce” button in the Authorize tab in WordPress, I then get redirected to SalesForce to login as expected and click “Allow”, but when I get re-directed back to WordPress, I see a message reading “Error 400: invalid client credentials”. This error is in the same location that the “Connect To SalesForce” used to be, before I clicked it and got directed to SalesForce.

    I think this may have something to do with the “Login Base URL” being set to (which is where I logged in when I created the “Connected App” in SalesForce.

    Any help would be appreciated.

    You might try this thread where someone had a possibly similar issue.

    But certainly it is not an issue with using You should always use that (for sandboxes) or (for production).

    Other possibilities, from what I can remember:

    1. Your other credentials are incorrect (the consumer key or secret)
    2. The Salesforce app hasn’t finished initializing (it takes several minutes for it to do this)
    3. Multisite (this plugin may not work in multisite environments)

    Thanks, I have read through that thread, but I’ll go back through it in case I missed anything.

    1. I did double check, but I will check again.
    2. I set up about 30 minutes ago, and still experiencing the issue.
    3. We are not running a multisite, just a normal WP installation.

    I’ll report back after going through that thread again.


    It’s working now 🙂 I think I just needed to wait longer. Sorry for the inconvenience and thanks for the quick reply.
