Let users call from your interface.
Add the Webphone SDK to a CRM or agent application. Your backend keeps the account API key and issues short-lived browser credentials; your interface provides the context and call controls.

you need to do.

Make calling part of a workflow.
Use Voice API for outbound calls and supported live-call actions, including speech and transfer flows. Decide how your application handles state, retries and the next step after the call.

Use the number APIs for supported ordering and routing operations, SMS APIs for messaging and lookup for number information. Process supported webhook events to update your application.

A practical sequence to shape the setup around your operation.
Choose the boundary
Decide what your application owns: users, customer records, business rules and the interface. Select the IllyVoIP operations needed for that workflow.
Build server-side access
Keep account credentials on your backend. Validate user access before creating browser credentials or making service requests, and handle documented errors.
Handle events and test outcomes
Verify webhook signatures, deduplicate deliveries and test retries and failure paths. Confirm charges and account requirements before running service operations.

Before you get started.
Ask our teamIs this a ready-made integration for every application?+
No. These are APIs and SDK tools for building your integration. HubSpot is a separate supported connector; other applications need the relevant development work.
Can the browser use the account API key directly?+
Keep the account key on your server. The Webphone SDK supports managed short-lived browser authentication; follow the current SDK guide for its setup.
Can we try requests in a playground?+
The portal provides API and SDK playgrounds. Requests can affect account services or incur charges, so review the operation and use appropriate test inputs before executing it.
