What does our implementation process include?

Sendy takes a unique developer-focused approach when integrating the Messaging Engine: our certified & skilled engineers develop a detailed understanding of your backend architecture.

1

Discovery & Scoping

Define webhook pathways, target endpoints, channel rules, and scale requirements.

2

Sandbox Provisioning

Generate secure credentials and test request payloads within a restricted simulator.

3

Integration & Tuning

Link BullMQ routers, synchronize database logs, and calibrate worker thread loads.

4

Scale & Monitor

Deploy live, register status callback listeners, and track delivery rates.

Transparent Tokenized Costs

The cost of adopting the Sendy application is carefully tailored. You simply pre-fund your wallet, and we handle all the complex provider billing automatically. We offer ₹10.00 free startup credits for testing.

How Tokenized Billing Works

We operate on a transparent pre-funded wallet system. You top up your account with credits, and costs are automatically deducted in real-time as you use the API.

WhatsApp Charges: Meta charges per 24-hour conversation, not per individual message. The exact cost depends on the conversation category (Marketing, Utility, Authentication, or Service) and the recipient's country code. Our platform automatically calculates the official Meta rate and deducts the exact equivalent token amount from your wallet.
