DEVELOPER PLATFORM
Build connected payment experiences with RapidCents
RapidCents is a payment platform software teams integrate through REST APIs, signed webhooks, Rapid.js hosted fields, SDKs and a sandbox with documented test cards. Terminal, checkout, payment-link and API payments land on the same merchant account, so reporting, refunds and settlement stay one integration.

- Signed webhooks
- Node and Python SDKs
- Dedicated developer support

Request sandbox access.
2. Create test payment
Use documented test cards.
3. Receive webhook
Verify signatures.
4. Go production
Guided migration.
