How to authenticate

  1. 1Become a Thunes member: sign a commercial agreement and complete compliance onboarding (no self-serve signup).
  2. 2Receive an API key and API secret plus environment-specific host URLs from Thunes.
  3. 3Authenticate requests with HTTP Basic auth using api_key:api_secret.
  4. 4Integrate the Money Transfer v2 flow: create a quotation, then create and confirm a transaction against it.
  5. 5Test in the pre-production environment Thunes provisions before being enabled for production.

Example request

curl -u 'API_KEY:API_SECRET' 'https://{thunes-environment-host}/v2/money-transfer/ping'

Notes for AI agents

Docs are public but everything else is gated: credentials and environment hosts are only issued after a signed member agreement and compliance review, so there is no self-serve sandbox. Relevant to SG builders as a Singapore-HQ network for wallet/bank payouts across emerging markets.
