What’s New in TriggerCallConnect API ?
The latest version of the TriggerCallConnect API brings more context and accuracy to every call made. In the previous iteration, only basic supporter information was accepted. Now, we’ve expanded the API to accept more granular location-based and demographic data, making your calls more targeted and meaningful.
New Fields Added
- County: Helps route the call to the correct regional representative.
- CongressionalDistrict: Targets the right legislative area.
- StateLegislativeDistrict & StateHouseDistrict: Drill down to local government representation for precise engagement.
This data can be used to customize call scripts, route calls based on districts, or even trigger workflows specific to each region.
