Support Tokens

Support tokens

Payout preview requires support_networks and support_tokens. This endpoint returns the allowlist for one chain. Copy the arrays into Preview Payout as a subset (typically the full list for that chain).

This catalog is not the same as Payin Currencies. Payin lists receiving / paying tokens for checkout; this list is the payout transfer and gas-token allowlist.

All requests must be authenticated with your API Key. Do not send merchant_id.

Response envelope

{
  "error_code": 0,
  "msg": "success",
  "data": {},
  "trace": "..."
}

note

Business success or failure is determined by error_code (error_code == 0 means success), not by the HTTP status code alone. See Error Codes.

Get support tokens

GET /support-tokens

Query parameters

Parameter	Type	Required	Description
chain_code	string	Yes	Chain identifier, for example morph, sol, trx.

Omitting chain_code is rejected with error_code: 90000.

Request example

GET /pro/merchant/payout/v1/support-tokens?chain_code=morph

Success response

{
  "error_code": 0,
  "msg": "success",
  "data": {
    "chain_code": "morph",
    "support_networks": ["morph"],
    "support_tokens": [
      {
        "network": "morph",
        "address": "0xToken...",
        "symbol": "USDT"
      }
    ]
  },
  "trace": "..."
}

Pass support_networks and support_tokens on preview without renaming fields. Preview is single-chain: every support_networks[] entry must equal tx_intent.chain.
