Guests in Webex are users with only a temporary identity and are often used for single-transaction collaborations. Examples include click-to-call and click-to-chat applications where the guest interacts with the agent only for the duration of the call or chat session. Guests in Webex are created and managed via a Service App with the scope guest-issuer:write and guest-issuer:read and are represented by a token with a fixed and predefined set of scopes.

Since the Service App manages its own pool of guests, you need to insert the Service App token into the developer portal's Try-It mode rather than your default personal token.

The guests/token endpoint is used to create and retrieve guest tokens, and the guests/count is used to assess the number of current guests.
