How it works

Integrate once, validate everywhere

A single developer-friendly approach across address, banking, identity and contact channels.

1

Get API access

Create a portal account and receive production keys. Test data and test keys let you validate your services before you switch them live.

2

Call the APIs

REST endpoints for each validation product with clear JSON responses.

3

Improve forms

Reduce typos, bounce-backs, misdirected payments and fake signups.

4

Scale with Etellect

Leverage group expertise from ePostcode, eSortcode and ePayment under one brand.

Developers

Validate address, bank, email, mobile and OTP flows with straightforward HTTPS requests. Full developer documentation and sample payloads are available while APIs are finalised.
