Integrations

Any system that can make an HTTP request can sync contacts into Whatbot. Here are the common paths.

n8n / Zapier / Make

Add an HTTP Request node:

• Method POST
• URL https://api.whatbot.in/public/v1/contacts
• Header X-API-Key: wa_live_xxx
• Body (JSON, array):

[{ "phone": "{{$json.phone}}", "name": "{{$json.name}}",
   "attributes": { "city": "{{$json.city}}", "source": "{{$json.source}}" } }]

Trigger it from a form submission, a new CRM row, a schedule, or a webhook — every new/updated contact flows into Whatbot in real time.

Sync a database on change

A tiny webhook handler that forwards a contact whenever your system creates/updates one:

Node.js

import express from "express";
const app = express();
app.use(express.json());

app.post("/on-lead-change", async (req, res) => {
  const lead = req.body;
  await fetch("https://api.whatbot.in/public/v1/contacts", {
    method: "POST",
    headers: {
      "X-API-Key": process.env.WHATBOT_API_KEY,
      "Content-Type": "application/json",
    },
    body: JSON.stringify([
      {
        phone: lead.phone,
        name: lead.name,
        tags: lead.tags,
        attributes: { city: lead.city, source: lead.source, budget: lead.budget },
      },
    ]),
  });
  res.sendStatus(200);
});

app.listen(3000);

Nightly batch from a CRM export

Python

import csv, requests

with open("leads.csv") as f:
    rows = list(csv.DictReader(f))

# batch to keep requests reasonable
for i in range(0, len(rows), 500):
    batch = [
        {"phone": r["phone"], "name": r.get("name"),
         "attributes": {k: v for k, v in r.items() if k not in ("phone", "name")}}
        for r in rows[i:i + 500]
    ]
    resp = requests.post(
        "https://api.whatbot.in/public/v1/contacts",
        headers={"X-API-Key": "wa_live_xxx"},
        json=batch, timeout=30,
    )
    resp.raise_for_status()

Tips

• Retry on 5xx/429 with backoff — upserts are idempotent, so retries are safe.
• Batch many contacts per request (one array) rather than one call each.
• Normalize phones loosely — Whatbot handles formatting, but include the country code when you have it.
