Use AssistCall with Textline

AssistCall answers your business calls 24/7 and can send each call, message and booking to Textline through Webhook, Live API actions, Zapier, Make, n8n.

Textline: Business texting platform with a shared team inbox for support, sales and operations teams.

Connects

Example call

A customer calls while your team is busy and asks for a delivery update. AssistCall takes the message, a Zap adds it to their Textline conversation, and an agent texts them back from the shared inbox.

• When AssistCall takes a message, a Zap runs Textline's Create/Update Contact and Import Contact Message. That adds the message to the contact's conversation as if they had texted it, so your team can reply from the shared inbox.
• During a live call, the receptionist creates or updates the caller as a Textline customer using your access token.
• When AssistCall books an appointment, a Zap or Make scenario runs Textline's Send Message to text the customer the confirmed time.

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.
