You can send an audio notification to the user using Voice Calls. Plivo’s PHLO allows you to quickly create and configure a voice alert system for your business. An API call from your application will trigger the PHLO and will enable making direct calls to the customers with critical alerts.
With PHLO, you can quickly create a workflow that suits your use case. Make sure you are registered and logged in on Plivo Console to proceed.
Use the following components to create this PHLO:
When the application send an API request to the PHLO, it triggers a call to the user’s phone number using the Initiate Call component. Once the user answers the call, the Play Audio component plays an audio to the user. The call will disconnect automatically after the playback audio is completed.
Note: The Callback function provides the user details required to make the call.
To create this PHLO:
On the top navigation bar, click PHLO. The PHLO page will appear and display your existing PHLOs, if any. If this is your first PHLO, then the PHLO page will be empty.
Click CREATE NEW PHLO to build a new PHLO.
Then, enter the information to retrieve from the HTTP Request payload. For example, this could be a variable for the list of numbers to call.
From the list of components, on the left hand side, drag and drop the Initiate Call component onto the canvas. This will add a Initiate call node onto the canvas.
Connect the Start node with the Initiate Call node, using the API Request trigger state.
The values for the From and To numbers are picked from the HTTP Request Payload. Make sure to clearly define the variables in the Start node.
Next, to configure the From and To numbers in the Initiate Call node, use the variables set in the Start node. Note:
The values for the From and To numbers are picked from the HTTP Request Payload. Make sure to clearly define the variables in the Start node.
Similarly, create a node for the Play Audio component and connect it to the Initiate Call node using the Answered trigger state.
Next, configure the Play Audio node to play a specific message to the user.
Note:
After you complete the configurations, click Save. You can trigger your PHLO using the PHLO URL to test it out. Your complete PHLO will look like this:
Once you have created and configured your PHLO, copy the PHLO Run URL. You can integrate a PHLO into your application workflow by making an API request to the PHLO URL with the required payload.

You can install the server SDKs and setup your development environment by referring to the instructions available in the below links:
Server SDKs
Setup your development environment
You can get your Auth_ID and Auth_token from your dashboard
You can find the PHLO_ID on the PHLO Listing page.
You can also use this PHLO structure for other use cases, like:
