For TypeScript, use the official @wazapin/sdk — typed builders, retries, and webhook helpers included. For every other runtime, call the REST API with your API key (X-Api-Key). Same endpoints, same payloads.

cURL

curl -X POST "https://api.wazapin.com/v1/messages" \
  -H "X-Api-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "channel_id": "wzp_ch_123",
    "to": "6281234567890",
    "type": "text",
    "content": { "body": "Hello from Wazapin" }
  }'

Python

import os
import requests

response = requests.post(
    "https://api.wazapin.com/v1/messages",
    headers={
        "X-Api-Key": os.environ["WAZAPIN_API_KEY"],
        "Content-Type": "application/json",
    },
    json={
        "channel_id": "wzp_ch_123",
        "to": "6281234567890",
        "type": "text",
        "content": {"body": "Hello from Wazapin"},
    },
    timeout=20,
)

response.raise_for_status()
print(response.json())
