SAP Business One Webhooks to Run Saltbox Workflows
First published on: 06/11/2026/10:02 am
As of SAP Business One V10 FP2602, SAP introduced Webhook functionality, enabling SAP Business One to dynamically notify a 3rd party system capable of receiving a webhook that a certain event has happened in Business One in real time.
This featured, coupled with the enormously flexible Saltbox workflow design, creates a plethora of opportunities to automate both internal B1 functions and also integration in real time to third party software providers.
Prerequisites:
SAP Business One V10 FP2602 or Later with Webhook Engine Installed
Saltbox Tenant
Saltbox Webhook Connector
SAP Business One Service Layer
Postman or Similar tool
Saltbox Setup:
1. Install the latest version of the Webhook Connector

Configuration in SAP Business One.
Creation of webhooks in Business One is done via the Service Layer, you will need to do with Postman or a similar tool of your choice.
1. Create a new request in Postman to Authenticate onto Service Layer, you will need to send the SAP Business One Company, username and password in the request body in JSON format to do this.
