Create Buy Transaction (v1)

Create Buy Transaction

Field notes (recovered from legacy docs)

Create External Buy

Price lock (quote_id)

Pass quote_id to create this transaction against a price-locked quote previously issued by the External Buy Quote endpoint (POST /api/v2/wallet/w/quote). When quote_id is supplied, the locked currency pair, payment method, amounts, network, and fees are resolved from the stored quote; the matching request fields become optional and any values sent for them are ignored. crypto_wallet_address is always required. When quote_id is absent the endpoint behaves as before and the original fields remain required.

{
  "quote_id": "421b9fb7-6800-4d9d-ba17-083ad662733b",
  "crypto_wallet_address": "0xf82010290b2c3169ffaB5354d7Bbd09Eb2822724",
  "source_id": "94b00193-301d-4750-b310-207393d987c9",
  "bank_transaction_id": "501610337776"
}

Response field values

Field	Possible Values
`status`	Typically `PROCESSING` immediately after creation
`failure_code`, `failure_desc`	Empty string until the transaction fails

If crypto_wallet_address is POOL_TRANSFER, the handler may also surface broker or deposit-address service errors directly with their underlying code and message.
