Ask HN: Building tools to make WhatsApp integration less painful for developers

So if you have some kind of experience integrating with WhatsApp Business API as a developer, you would already know how tough it gets. I am planning to build a tool that is specifically intended to solve the developers problem regarding the following specific things:

1. Easy Onboarding with embedded setup with bank grade security (data encryption and security first approach)

2. Secure and scalable Send Message API supporting all message formats.

3. Secure and scalable Webhooks for incoming messages, delivery reports etc

4. Embedded Components for resellers like Meta Onboarding, Template Management etc.

5. Attractive Pricing

Yes, on the face of it, it would look like a WhatsApp API Wrapper, but behind the scene, we would be doing a lot of security, scalability, use-cases related solutions.

This is somewhat similar to what Twilio offers or several other enterprise provider offers but at a very high cost and with a lengthy sales cycle. I am going to provide the same thing but with excellent experience and attractive pricing.

I am not going to build Chatbot, Abandonded Cart or things directly for end-customer but my product is targeted to developers specifically who are sending more than 50k messages per month.

I want to know from you regarding your experience using WhatsApp Business API. Where did you hit friction - onboarding, approvals, webhooks, SDKs, scale, costs?

Would you mind sharing few of your experience?
