You are now ready to generate your Webhook URL that will be used by MessageMedia to process inbound messages. This is done in Step 5 of the Setup & Configuration page.
In the ‘Secure Web Address’ Picklist, select the Mercury Force.com Site that was created in Step 2 and click ‘Generate Webhook URL’
If you are using a Dedicated Number and/or you have Inbound MMS enabled on your MessageMedia account, you will need to register the Webhook URL with MessageMedia. In the Select Webhook Picklist, select ‘New Webhook’ or if you’ve already got an existing Webhook URL registered with MessageMedia for this account, you can select to overwrite that one. Once you’ve made your selection, click Save Webhook.
Once the Webhook has been updated with MessageMedia, you’ll see the ‘Webhook configured correctly’ icon.
