Developer platform

Connect your accounts to the systems you already run.

Read balances, reconcile transactions and trigger payouts programmatically. Test everything against a sandbox before a single dollar moves.

REST API

Accounts, balances, transactions, recipients and payouts, over a single authenticated API.

Signed webhooks

Events on every state change, signed so your endpoint can verify they came from us.

Scoped credentials

Separate keys per environment, with least-privilege scopes and rotation you control.

Sandbox first

Build and test against a sandbox with mock providers before touching production.

Statements and exports

Pull statements per account and period straight into your accounting or reporting stack.

Rate limits and audit

Documented limits, and an audit trail of every action taken through the API.

What teams build with it

The API exists to remove manual steps from finance operations, not to be a product in its own right.

  • Automatic reconciliation of transactions against your ledger
  • Balance and liquidity dashboards inside your own tooling
  • Scheduled contractor and supplier payout runs
  • Alerting when a balance falls below a threshold
  • Pulling statements into your accounting system on a schedule

FAQ

Questions about developer platform

Cannot see your question? Ask us directly.

Is API access available on every plan?

API access is aimed at business accounts. Tell us what you plan to build and we will confirm availability and any limits that apply to your account.

Is there a sandbox?

Yes. You should build and test against the sandbox first. Production credentials are issued separately and should never be committed to a repository.

How are webhooks secured?

Webhooks are signed. Your endpoint should verify the signature and reject replays before acting on any event.
