How to create Webhooks
Webhooks are for making HTTP requests. When the post is shared, a web request is created according to the settings (header, parameters, query parameter, JSON body, request method, request URL) set by the client and stored in the webhook account.
When a post is shared through fs poster, just as it is shared to other social networks, the website sends a request according to the settings.
With this tool, if you have your specific API, you can use this tool to share a post or make some changes.
To create a webhook, go to the Accounts tab => Webhooks menu and click the Add a webhook button;
Fill in the required fields and click the Add button.
