Connects

Example call

A med spa gets a call at 9 pm asking about Botox pricing. The receptionist answers, takes the caller's name and number, and books a consultation. A Make scenario creates the contact, a note with the booking details and a follow-up task in HighLevel, and the spa owner sees the new lead in their sub-account the next morning.

• During a call, the receptionist uses a Private Integration Token to check the sub-account for a contact with the caller's number, so returning clients are greeted by name.
• After a call, a Make scenario creates the contact in HighLevel, adds the call summary as a note and creates a follow-up task.
• lead.captured events go to the LeadConnector app on Zapier, which adds or updates an opportunity in the right pipeline stage.

How it connects

• Webhook: Signed JSON for every call, message and booking, sent to any HTTPS URL you choose.
• Live API actions: During the call, the receptionist calls the app's API with your key to look up or create records.
• Zapier: Send AssistCall events to a Zap (Webhooks by Zapier, Catch Hook), then use the app's Zapier actions. Needs a paid Zapier plan.
• Make: Start a Make scenario with a custom webhook and use the app's Make modules.
• n8n: Start an n8n workflow with a webhook node, then call the app with its node or an HTTP request.
• Call forwarding: Forward your business line to AssistCall when busy, after hours or always. Works with any carrier.

HighLevel says its Starter and Unlimited plans include basic API access, and Agency Pro adds advanced access with agency-level keys. Private Integration Tokens are created under Settings > Private Integrations and are available to agencies and sub-accounts. Agency admins can create them by default. Tokens do not expire, but HighLevel recommends rotating them every 90 days. Documented OAuth limits are 100 requests per 10 seconds and 200,000 a day per location. Requests also need a Version header. HighLevel's Zapier app is listed under its LeadConnector brand.
