Quickstart
Campaigns and agents are created in the HollrAI platform. The API is used to trigger calls under an already-configured campaign and to read the resulting conversations.
Create a campaign
Sign in to app.hollr.ai and create a campaign, for example “Lead Qualification”. A campaign is the container you’ll use to organize calls and attach an agent to.
Copy the campaign ID — you’ll use it in every API call below.
Create an agent under the campaign
Still in the platform, create the AI voice agent for the “Lead Qualification” campaign. Set its name, opening message, system prompt, voice, and the languages it should support.
Get an API key
Get your API key from app.hollr.ai and export it so the examples below can use it.
See authentication for more on API keys.
Trigger a call
Trigger a single outbound call to a phone number using the agent attached to the campaign.
For larger batches, use the bulk calls endpoint.
