Inbound Webhooks

Inbound Webhooks are unique endpoints that can be embedded into your applications to notify Webex Connect of events occurring in the your application(s).

In essence, they work the same way as custom event API v1 but are flexible with the input JSON/XML body that will be parsed as JPath/Xpath and the variables will be made available in flows/rules.

We support two types of authentication for inbound webhooks: a. service key based, and b. JWT based authentication. When authentication is enabled you need to use one of service key or JWT credentials associated with the relevant Webex Connect service which contains the rule/flow you've associated the inbound webhook with.

In addition, we offer support for signatures (using SHA1, SHA 256, or SHA 512) within headers of inbound webhooks that trigger flows. It will add an additional layer of security to your inbound webhook requests and help safeguard against potential security threats. When signatures are enabled, invalid requests will return an HTTP 400 error.

Once an inbound webhook has been configured, it can start accepting any JSON/XML payload. The payload is passed to the linked rule and/or flow. You can also enter example JSON or send a live request to parse. These parameters will be saved and available for usage in rules and flows when you start typing with $ to search for a variable.

Here is an example of how a sample JSON is parsed.

            "title":"JSON API paints my bikeshed!",
            "body":"The shortest article. Ever.",
