Dialer API

Dialer endpoints exposed by the Devotel CPaaS API Base path: /api/v1/dialer Endpoint count: 22

title: “The preview-dial loop” description: “How the two preview-mode operations chain: claim a contact atomically, review it on the agent’s screen, then launch the dial.”

The preview-dial loop

Outbound-campaign operators run the dialer workspace. Progressive, predictive, and agentless campaigns fire through the pacing scheduler automatically; preview mode is the one where a human reviews each contact card before the call launches. That human loop compresses into two endpoints. First the agent’s frontend claims the next contact with GET /api/v1/dialer/next-call:
cURL
The claim is atomic — two agents polling concurrently never receive the same number — so the response is the work ticket the agent then reviews on their screen. preview_decision_seconds is the per-campaign review countdown; decision_expires_at is the server-side deadline for that countdown. 204 No Content means the campaign is progressive / predictive / agentless (calls fire automatically); 404 means the campaign is not active. A null contact means the list is drained. Once the agent clicks “Call” the dial launches:
cURL
The contact must still be in the dialing (claimed) state, or the request rejects with 409 CLAIM_NOT_HELD. The requesting operator records as the call’s agent for the TCPA audit trail, and the call itself exits through the Devotel softswitch — the preview loop never dials a number outside the commit path.

SDK surface bridge — List outbound-dialer campaigns, queue the next hop of the campaign FIFO, or trigger one alias lane — all with the sandbox key.

These three tabs mirror SDK status and coverage. Python fronts client.request, Go fronts client.Request, and TS fronts fetch-TS — each with the sandbox key.

List dialer campaigns

GET /api/v1/dialer/campaigns
Cursor-paginated list of every non-deleted campaign the tenant owns, newest first. Each row includes rolled-up contacts_total / contacts_connected counts (bounded scan — see contacts_count_capped_at). Degrades to an empty list (never a 5xx) when the tenant’s dialer schema is not yet provisioned.

Claim the next preview-mode contact for an agent

GET /api/v1/dialer/next-call
Hands the agent frontend the next contact to review for a preview-mode campaign, atomically claiming it so two agents polling concurrently never receive the same number and double-dial. Returns the claimed contact plus the per-campaign decision countdown, 204 No Content for progressive / predictive / agentless campaigns (their calls are originated automatically by the pacing engine), or 404 when the campaign is not active.
