Initiate a request - please refer to the list of API response codes in the Insights section for the details... Once you obtained an webid_url, please embed the webid_url in an iframe or webviewer. webid_key is the unique reference for each request. The mode (production or sandbox) will be calculated based on domain/ip address from which we receive the request. Please contact support to setup the mode.Note : You can pass a custom header webhook_url to receive the webhook callbacks. If nothing is specified, it uses the default webhook_url given during the subscriber setup. This option isn't available for production IP address.
