Atlas DocumentationChangelog
New features, improvements and fixes to the Atlas API and dashboard.
July 2026
Amounts are always positive
amount is now always a positive number in transaction, payout, checkout, card, payment link and FX swap responses. Use the transaction type to tell money in from money out.
What you need to do
If you relied on a negative amount for outflows, use the transaction type instead.
Checkout redirects fall back to your redirect URL
When a checkout has no redirect_url, customers are now sent to the redirect URL set on your account after they pay. Atlas adds checkoutReference to the query string so you can match the customer to the checkout.

More ways to look up a checkout
New checkout endpoints:
March 2026
Checkout transactions confirm faster
Checkout transactions now show successful as soon as Atlas is notified of the inflow, instead of waiting for the inflow to be fully resolved.
What you need to do
Nothing. If you poll checkout status, you see successful sooner.
December 2025
Checkout transactions include the session ID
Checkout transaction responses now include sessionId, the session ID the bank assigns to the transfer. Use it to trace a payment with the paying bank.
See the checkout guide.
