Where do I get my FBR security token?
Sandbox and production tokens are issued by PRAL/FBR.
The security token is issued by PRAL for FBR, through the IRIS portal (Digital Invoicing) or your licensed integrator. You first receive a sandbox token for testing; the production token is issued after your integration is authorised.
Paste the token in FBR Settings > Credentials and click Test connection. Tokens are never displayed again. See the FBR Integration Guide.
