About Gravv

Gravv connects traditional finance rails through a single API.

This documentation covers the Wave Transfer SNS integration using:

  • POST /v1/external-accounts to create transfer destinations (External Account / Recipient)
  • POST /v1/transfer/sns to initiate Transfer SNS end to end
  • transfer status webhooks (transfer.status.pending, transfer.status.completed, transfer.status.failed)

Integration workflow

  1. Set up credentials and environment access in Get started.
  2. Configure request auth in Authentication.
  3. Create and activate an External Account (Recipient) via POST /v1/external-accounts.
  4. Initiate Transfer SNS via POST /v1/transfer/sns.
  5. Process transfer lifecycle events in Webhooks.
  6. Use the interactive API reference for request/response schemas.
