⚒️ Test IVR call quality using the CALL-E API from a phone task list

⚡ 24 views · ⚒️ Engineering

Description

Quick overview

Manually run two authorized IVR quality checks using CALL-E Calls API v2. The workflow processes calls sequentially and returns masked outcomes, structured results, transcripts, and metadata. Replace blocked placeholder numbers before live execution.

How it works

1. Runs when you start the workflow manually.
2. Loads polling settings from CALL-E Config. The create node reads CALL_E_API_KEY from the n8n deployment environment or secret store and sends requests only to https://api.heycall-e.com.
3. Validates the E.164 phone/task rows and blocks the shipped placeholder numbers. Loop Over Calls processes one row at a time.
4. Builds one phone per POST /v2/calls request, with a required closed scalar result_schema, metadata, and an Idempotency-Key derived from the row ID and original call inputs.
5. Polls GET /v2/calls/{id} while result_status=pending, for up to four minutes. Polling stops for available, unavailable, or not_applicable; telephone completion alone does not mean the result is ready.
6. Reads call_outcome, result_status, result, error, the top-level transcript, and metadata. Formats a masked per-call result and an execution summary, including unavailable results without automatically redialing.

Setup

1. Create a CALL-E API key and set CALL_E_API_KEY in your n8n deployment environment or secret store. Keep the key out of workflow JSON and Code-node item data.
2. Import the workflow and replace both blocked placeholders in Phone/Task List with owned or explicitly authorized E.164 test numbers. Review each row’s task, locale, and metadata.
3. Review CALL-E Config: pollIntervalSeconds defaults to 5 (allowed 1–30); waitTimeoutMinutes defaults to 4 (maximum 4). Keep the workflow inactive until reviewed, then execute manually to place real calls. This template has no dry-run mode.

Requirements

• Use a self-hosted n8n deployment where the administrator permits trusted Code nodes to read CALL_E_API_KEY. Environment access restrictions stop execution. No separate CALL-E community-node package is required.

Customization

• Use a stable callItemId for each intended call. Re-running unchanged rows replays the original calls. Changing a row ID or call inputs changes the key and may place another call.

Additional info

A wait timeout or stopped n8n execution does not cancel the call. Retain the API id and resume with GET /v2/calls/{id}. If creation acceptance is uncertain, replay only the original saved request and key. The template never automatically retries creation. Use id for API reads; call_id is a separate Billing identifier and may be null.
