OVERVIEW
As of August 2020 (v4.5), you can setup multiple web hooks for a single company. This allows you to set up multiple web hooks under a single Company ID in the event that you have multiple currencies being posted to different locations.
SETUP
Navigate to Admin > Master Files > Company, then select the company you are configuring the web hook for (you do not have to click "Edit" for that company, just select anywhere in it's cell). Afterward, select the "Web Hooks" button in the "Web Hooks" section at the bottom of the page.
Once the window appears, you will need to select "Add New Record" to create a new web hook. The window will appear for you to configure the web hook. Make sure you select the currency used with this web hook in the "Currency ID" drop-down.
Follow the below articles for an overview on how the web hook might be setup.
Once the web hook has been set up, save the record then return to the web hook window. You will see your newly created record. From here, you can either edit the existing record or select "Add New Record" again to add additional web hooks.
