🚀 New REST API Methods to Create and Update Campaigns in SIP Caller

Two new REST API methods just landed in SIP Caller: you can now create and update campaigns directly from your own systems.

Until now, integrators could automate almost every part of the campaign lifecycle through our API, but campaigns themselves still had to be created and configured from the Web Console. With this release, that last piece falls into place.

Create Campaign

The new POST /campaigns endpoint lets you create a fully configured campaign in a single API call, including its dialer mode, retry intervals, working hours, time zone, call handling (Callflow or AI Agent), Voicemail Detection settings, and blacklists.

Update Campaign

The new PUT /campaigns/CAMPAIGN_ID endpoint accepts the same fields as creation, so you can adjust a campaign's settings programmatically as your needs change, without ever opening the console.

Why This Matters

These two endpoints unlock use cases that simply weren't possible before, such as:

• Spinning up a new campaign automatically whenever a batch of leads lands in your CRM
• Adjusting retry intervals, working hours, or dialer intensity on the fly, based on external business rules
• Building your own campaign templates and provisioning tool on top of SIP Caller, without any manual step in the console

Full Campaign Lifecycle, Now Available via API

Create and Update Campaign complete a set of endpoints that already covered the rest of a campaign's life:

• Create a campaign — define it from scratch, with any dialer mode and configuration
• Update a campaign — change any of its settings at any time
• Duplicate a campaign — clone an existing one, optionally with a new name and a filtered set of numbers
• Change campaign state — activate, pause, resume, or cancel a campaign
• Add numbers to a dynamic campaign — feed new numbers, with or without variable values, one by one or via CSV upload

Put together, this means the entire campaign lifecycle, from creation to completion, can now be automated end-to-end from your own systems, with no manual step required in the SIP Caller console.

Example Use Case

Imagine a nightly job that queries your CRM for accounts with an overdue balance, creates a fresh collections campaign for the day, adds the corresponding numbers with their amount due as a variable, activates the campaign, and cancels it automatically once your business hours end. All of that is now achievable with a handful of API calls.

Designed for Seamless Integration

These new endpoints are ideal for:

• Resellers embedding SIP Caller into their own platforms
• Businesses that generate campaigns dynamically based on external data
• High-volume operations that need full control over campaign provisioning, without manual intervention
