API & Third-Party Integration

Make your apps talk to each other.

Most businesses already have the right tools — they just don't share data. An order typed twice, a payment matched by hand, a customer who never got the update. Integrations fix that, usually in days, not months.

Infovion Technologies integrates business software with payment gateways (Razorpay, UPI, Stripe), WhatsApp Business, SMS and email, GST e-invoicing and e-way bills, Tally, Google Workspace and other REST APIs — and builds secure custom APIs so your own apps, partners and mobile apps can share data.

FAQ

Questions about API integration

Can you integrate Razorpay so payments go to our own account?

Yes. We integrate your own Razorpay account, so money settles directly to your bank. We built exactly this for our school ERP, where parents pay fees by UPI into each school's own account.

Can our software send WhatsApp messages automatically?

Yes, through the official WhatsApp Business API with approved message templates, or through simpler click-to-chat links where full automation isn't needed.

Can you integrate with Tally?

Yes. We export vouchers and masters in a format Tally imports, or sync through Tally's XML interface where available.

How long does an API integration take?

A standard integration like a payment gateway takes about 1–2 weeks including testing.
