Remitflex Documentation

Cross-chain pay-in: payer sends on one network (Bitcoin, Ethereum, Tron, etc.), you receive stablecoins on Base or Solana. Each route gets a persistent depositAddress. Scopes: api:read, api:write For hosted checkout, use Payment links instead. Discover supported networks in Networks & corridors. Full table: Corridor matrix.

Settling Solana EURC ↔ USDC as a collection path is fine for pay-ins. For treasury conversion with rates and a deposit lifecycle, use Swaps.

{paymentRouteId} is the RemitFlex payment route UUID returned by POST or GET /payment-routes.

Method	Path	Purpose
`POST`	`/payment-routes`	Create route
`GET`	`/payment-routes`	List routes (`?customerId=` optional)
`GET`	`/payment-routes/{paymentRouteId}`	Get route
`GET`	`/payment-routes/deposits`	All deposits (`?customerId=` optional)
`GET`	`/payment-routes/{paymentRouteId}/deposits`	Route deposits
`POST`	`/payment-routes/{paymentRouteId}/deposits/sync`	Refresh deposit state
`DELETE`	`/payment-routes/{paymentRouteId}`	Archive route

Create

Use network keys and token codes from Networks & corridors — not chain IDs or contract addresses:

curl -X POST https://api.remitflex.io/v1/payment-routes \
  -H "Authorization: Bearer $REMITFLEX_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Treasury inbound",
    "originChainKey": "tron",
    "destinationChainKey": "base",
    "destinationCurrency": "USDC",
    "destinationAddress": "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb"
  }'

Field	Description
`originChainKey`	Where payers send (e.g. `bitcoin`, `ethereum`, `tron`, `base`)
`destinationChainKey`	Where you receive — `base` or `solana`
`destinationCurrency`	Token code — `USDC` or `USDT` on Base; `USDC`, `USDT`, or `EURC` on Solana

originChainKey and destinationChainKey are required when creating routes or payment links. Remitflex resolves networks internally — customers never send or receive chain IDs. Response includes depositAddress — share with payers on the origin network.
