Hello all,

I have been trying to setup integration between Stamps.com & Acumatica but upon testing the connection it shows the following:

How to resolve this?

Update:
Found the below info on Stamps.com website:


I tried to test the connection using the Staging Endpoint URL as highlighted above, but now it displays “Authentication failed” error message. I also found out that i needed to register for a developer account. So just waiting to get it started and again test the connection.

​@Harry Hi I faced the same issue and confirmed a few things via Stamps.com and Acumatica Support - sharing here in case you are still having an issue:

  1. You don't need a developer account
  2. You want to use https://swsim.stamps.com/swsim/swsimv135.asmx regardless of what environment you are in

If you are getting the message of “Authentication failed” this suggest the the username and password is in correct. I test by changing my credentials and got the same error. 

 

Like Harry said, i’m using the same url and no dev account.
