Truecaller for Business API
REST APIs for Truecaller's Verified Business Caller ID platform. Partners exchange a Key ID + Secret API Key for a 60-minute bearer token (POST /clients/{clientAccountId}/token), then push dynamic caller-ID personalisation in real time (POST /v2/clients/{clientAccountId}/dynamic_call_record, 100 rps per token) or batch, check batch status, read dynamic labels, list/delist business numbers under feature sets, and run Verified Campaigns (bulk upload and exit via enterprise-webhooks-noneu.truecaller.com). Call Me Back and User Feedback events are delivered by configurable webhooks.
