WhatsApp AI Agent

Is respond.io for you?

Use the criteria below to see if respond.io fits your team — without a platform behind the API connection, leads sit unassigned, context gets lost, and follow-ups slip as volume grows.

Respond.io is for you if you want:

  • To manage high chat or call volumes with AI and human agents
  • To centralize omnichannel conversations across multiple teams or locations
  • CRM context in conversations

Not for you if:

  • You only need one-way bulk messaging or cold outreach — a lighter broadcast tool fits better
  • Under 500 conversations a month, or need group messaging — not supported by WhatsApp API
  • Your business type violates Meta's policies (e.g. gambling)

FAQ: WhatsApp Business API and AI Agent — answered

Is respond.io the right platform for running WhatsApp Business API, or would a simpler tool work?

Yes — respond.io is a full customer conversation platform, not just a shared inbox, with AI Agents, CRM sync and lifecycle tracking built for mid-market B2C teams running multi-agent, revenue-critical conversations. If you're a single-agent business with low volume and no need for automation, a simpler WhatsApp API client may be enough.

Is respond.io just a WhatsApp BSP?

No, respond.io is not just a WhatsApp BSP — it also gives you the platform to run on top of that access: AI Agents, a shared inbox, CRM sync and lifecycle tracking, so your team manages conversations, not just sends messages.

How does respond.io's WhatsApp AI Agent handle real customer conversations?

Respond.io's WhatsApp AI Agent is trained on your product knowledge base and qualification criteria to answer questions, qualify leads, sell, book appointments, and close conversations — not just route them. It hands off to a human with full context the moment a query exceeds its scope, and runs 24/7.

Does respond.io integrate with my CRM or other business tools?

Yes — respond.io syncs natively with Salesforce and HubSpot, and connects to any other CRM through Zapier, Make.com, n8n or HTTP Requests. It's not a CRM replacement — it keeps your CRM as the system of record while feeding it live conversation data, so reps and managers aren't working off disconnected records.

Can I switch my existing WhatsApp number to the API without losing it?

Yes, if the number isn't currently active on the WhatsApp Business App or Messenger — it needs to be removed from the app first, then it can connect to the API. When you migrate to respond.io from your BSP, you keep your number, templates, contacts and conversation history — nothing gets rebuilt from scratch.

How much does WhatsApp API cost, and does respond.io add any markup?

No — respond.io doesn't add message markups or setup fees. WhatsApp API pricing follows Meta's conversation-based model (charged per 24-hour window, rates vary by country and category) plus your respond.io subscription plan — Meta bills directly or through your BSP depending on setup. See the respond.io pricing page for plan details.
