Quick Integration Guide

Get Your Client Credentials

Ready to integrate? Just fill out this form with:

• Company Name
• Short Company Description
• Company website
• Logo (PNG, 56x56)
• Required Permission Scopes
• Redirect URIs
• RSA Public Key (2048+ bits, PEM format)
  • One for test, one for production is ideal!

Note: If your app has no backend (e.g., runs entirely on users' devices), just ask for a public client ID, no secret or public key required.

Generate Your RSA Keys

openssl genrsa -aes128 -out private.pem 4096
openssl rsa -in private.pem -pubout > public.pem

Decrypting Your Client Secret

echo -n "<encrypted secret>" | base64 -d | openssl rsautl -decrypt -inkey private.pem
