Connects

Example call

An insurance prospect calls while the agent is meeting a client. The receptionist takes their name, number and the policy they're asking about. A Zap creates the contact and a task to call back, and the agent sees the task in Less Annoying CRM.

• After a call, a Zap finds or creates the caller as a contact in Less Annoying CRM and adds the AssistCall summary as a contact note.
• Urgent message.taken events create a task in Less Annoying CRM through Zapier, so the callback shows on the owner's task list.
• lead.captured events create a pipeline item for the new contact through Zapier.

How it connects

• Webhook: Signed JSON for every call, message and booking, sent to any HTTPS URL you choose.
• Zapier: Send AssistCall events to a Zap (Webhooks by Zapier, Catch Hook), then use the app's Zapier actions. Needs a paid Zapier plan.
• 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.

About Less Annoying CRM's API

• Self-serve API: you can create a key in your account
• Style: JSON over HTTPS POST (API v2: a Function name plus a Parameters object)
• Authentication: API key in the Authorization header, created on the Programmer API settings page
• On Zapier: yes. On Make: no.

Each key can be limited to read, create, edit or delete, and an admin can turn API access off for the whole account. Every call is a POST to https://api.lessannoyingcrm.com/v2/ with a nested Parameters object. AssistCall's live API step sends flat JSON, so live lookups are not offered. Webhooks are created with the CreateWebhook API call and signed with HMAC-SHA256. No Make app was found.

Not included: no one-click Less Annoying CRM app, no listing in Less Annoying CRM's marketplace, no two-way sync, and no partnership with Less Annoying Software.
