Why teams choose Allidian
Minutes
From sign-up to a test payment
Create an account, get sandbox API keys and run a full payment, refund and webhook cycle the same day.
1 API
For every way you get paid
Hosted and embedded checkout, payment links, invoices and subscriptions share one integration and one dashboard.
0 card numbers
Stored on your servers
Customers type card details into the payment provider's secure fields, so raw card data never reaches your systems or ours.
Every way to get paid, in one place.
Start with the tool you need today. Add the rest later without a new integration.

Approval to accept payments is the provider's decision. How provider-powered payments work
Security
Safe at every step.
Built so the most sensitive data never touches your servers, with controls that protect your account and your customers.
Tokenized card entry
Card fields are hosted by the payment provider. You work with tokens, never card numbers.
Signed webhooks, hashed keys
Every event is signed and timestamped. API secret keys are shown once and stored only as hashes.
Two-factor and audit logs
Protect your team with two-factor sign-in, role-based access and an append-only audit trail.
