<Curl/>

The <Curl> command in Opentact XML call flows empowers users to integrate and interact with external web services seamlessly. This command enables making HTTP requests during a call, allowing dynamic interactions and data exchange with external systems. The <Curl> command is a powerful tool to extend the capabilities of Opentact, making it a versatile solution for various telephony applications.

Purpose of the <Curl> Command

The primary purpose of the <Curl> command is to send HTTP requests to external endpoints, facilitating real-time communication with web servers, APIs, or any HTTP-enabled services. This integration capability enables Opentact users to fetch, push, or manipulate data during a call, enhancing the interactive nature of telephony applications.

Key Features

• Dynamic Interaction: The <Curl> command allows dynamic interaction with external services based on the context of the call flow.

• Data Exchange: It facilitates the exchange of data between Opentact and external systems, opening up possibilities for personalized and context-aware call experiences.

• Request Customization: Users can customize HTTP requests by specifying various parameters such as method, headers, body content, and more.

• Response Handling: Opentact can handle responses from external services, providing the flexibility to make decisions based on the received data.

Usage Hints

• URL Configuration: The url parameter specifies the endpoint to which the HTTP request is made.

• Request Method: Users can define the HTTP method (GET, POST, etc.) using the method parameter.

• Timeout: The timeout parameter sets the maximum time allowed for the HTTP request.

• Response Handling: Users can decide how to handle the HTTP response, whether to include it in the call flow or simply acknowledge the request.

Examples

Here are some examples illustrating the usage of the <Curl> command in Opentact XML call flows:

<Curl url="https://api.example.com/data" method="GET" timeout="5000" />

<Curl url="https://api.example.com/update" method="POST" body="{'key':'value'}" />

Integration Scenarios

• Data Retrieval: Fetch information from external databases or APIs to provide real-time updates during a call.

• Service Integration: Integrate Opentact with third-party services to perform actions based on call events.

• Customization: Dynamically customize call flows by fetching data from external sources.

The <Curl> command adds a layer of sophistication to Opentact call flows, allowing users to seamlessly integrate telephony processes with external services.
