Webhooks & REST API: Connect Smart Growth AI to Your Own Systems

When a spreadsheet is not enough

Our free Google Sheets integration covers a lot of teams. But hospitals with a patient system, NBFCs with a loan origination platform, or institutes with their own ERP usually want campaign data to flow straight into the software they already run. That is what our webhooks and API are for.

Three ways to connect

1. Outgoing webhooks: we send data to you

When something happens in a campaign, we can post it to your endpoint. Typical events include:

• A new lead from a WhatsApp form, website form or Meta lead ad
• A person pressing 1 or 2 on a voice call, with listening duration
• A WhatsApp or RCS reply, or a button tap
• An opt-out request, so your system can respect it too

2. Custom form API: your forms, your fields

WhatsApp forms and website forms built with Smart Growth AI can post their answers directly to your endpoint or CRM through the custom form API. You decide the field names, so the data arrives in the shape your system expects. More detail is on the custom form API page.

3. Dynamic API chatbot: we call your APIs

This is the reverse direction. During a WhatsApp conversation, the dynamic API chatbot can call your API and reply with real data. A parent can check pending fees, a customer can see order status, a patient can pick from open appointment slots, or a student can see seats left in a batch, all inside the chat.

How it works

• Tell us what you need. Which events, which fields, which endpoint. A short call with your developer is usually enough.
• Share your endpoint details. URL, authentication method and the expected payload format.
• We map and test. We send test payloads, check them with your team, and fix any field mismatches before going live.
• Go live and monitor. Our support team stays reachable by phone and in a dedicated WhatsApp group if anything needs a tweak.

Full technical documentation, authentication details and sample payloads are shared with your developers during onboarding, so the setup matches your system rather than a generic template.

Connecting popular CRMs

Many customers use this to connect CRMs such as Zoho CRM, HubSpot, LeadSquared and TeleCRM. These connections run through webhooks and API, not through an app listed in those CRMs' marketplaces. In practice this means you get a direct, flexible connection with fields mapped the way you want.

API data inside the Smart Growth AI Campaign

When you run the Smart Growth AI Campaign, every stage produces useful signals: who listened under 10 seconds, who listened 10 to 25 seconds, who listened past 25 seconds, who pressed 1, and who replied on WhatsApp or RCS. With webhooks, those signals can update lead scores in your own system as they happen, so your sales or admissions team works from fresh data rather than an end-of-day export.

Who should use the API

• Teams with an in-house CRM, ERP or hospital system
• Businesses that need chat replies based on live account data
• Agencies and developers building workflows for their own clients

Security and reliability

We agree the authentication method with your team, such as a secret key or token in the request, and only send the fields you ask for. If your endpoint is down for a while, tell us how you want retries handled. Keeping the Google Sheet running alongside your system is also a simple safety net.

Not sure if you need it? Start with the Google Sheet and move to the API when you are ready. Book a call and we will help you decide.
