Step By Step: Integrate With a Website
You can use any backend like PHP, Node, Python, Java, or .NET. The steps are the same.
Step 1: Get your API details
- Log in to your KAPSystem dashboard
- Find your API key or token
- Note your base API URL
- Note your sender ID or header
- Note your template IDs if you use template based flows
Step 2: Pick message type
- Transactional SMS for OTPs, login codes, order updates, alerts
- Promotional SMS for offers and campaigns
Step 3: Build a simple request
Most systems call an HTTPS endpoint with fields like:
- Your API key or token
- Sender ID
- Recipient mobile number with country code
- Message text or template ID with variables
- Optional fields like callback URL for delivery reports
Think of it like a small form that your code submits behind the scenes.
Step 4: Send a test SMS
- Use a known test number
- Keep message short and clear
- Check the API response code
- Verify the SMS arrived on the phone
Step 5: Handle the API response
Your code should read the response and store:
- Request ID or message ID
- Status from KAPSystem
- Error message if any
Step 6: Save logs
Store every API request and response for a few days. It helps in support and audits.
Step 7: Go live with small volume
- Start with a small group
- Watch delivery and timing
- Fix any issues before sending in bulk
Step By Step: Integrate With a CRM
You can connect KAPSystem to many CRMs by using:
- Built in webhook or API features in your CRM
- A small middleware script on your server
- Simple no code tools if your CRM supports outbound webhooks
Common CRM integration flow
| Task | CRM action | KAPSystem effect |
|---|---|---|
| New lead created | CRM triggers webhook to your server | Your server calls KAPSystem API to send welcome SMS |
| Stage changed | CRM sends event info | Your server sends a follow up SMS based on the stage |
| Meeting booked | CRM calls your webhook | Your server sends a reminder SMS before the meeting |
| Payment received | CRM sends event | Your server sends a thank you SMS or receipt link |
| Ticket closed | CRM event fires | Your server sends a feedback request SMS |
If your CRM can call an external URL, point it to your webhook. Your webhook then calls the KAPSystem API.
Template Based Messaging
In many cases you will use pre approved templates. These help pass filters and keep rules simple. Your request includes a template ID and variables.
| Field | Example | Notes |
|---|---|---|
| template_id | TXN_OTP_001 | Approved in your account |
| variables | name, otp | Inserted into the message |
| sender_id | KAPSMS | Your header or sender ID |
| to | 9198XXXXXXXX | Customer phone with country code |
Personalization and Variables
Use variables to make messages feel friendly and clear.
| Use case | Variables | Example message idea |
|---|---|---|
| OTP | name, otp, brand | Hello Riya, your KAPSystem login code is 482193. Do not share this code with anyone. |
| Order shipped | name, order_id, link | Hi Arjun, order OD12345 is on the way. Track your package here short link. |
| Appointment | name, date, time, place | Hello Meera, your doctor visit is on 12 Oct at 4 pm at City Clinic. Reply 1 to confirm. |
| Promo | name, offer, end_date | Hi Ahmed, get 15 percent off till Sunday. Use code SAVE15 on checkout. |
Small note: keep messages short and simple. One clear action.

Data and Security
Keep user data safe. It is very important.
| Area | Best practice |
|---|---|
