3 endpoints for payment methods: get by ID, get by user, and list all valid methods. All require HMAC authentication.
EP-37: URL Discrepancy Between AutoP2P and PDF
The PDF documents this endpoint under the paymentMethod controller as a GET request. AutoP2P production code uses a different controller path and method. Both paths appear to be functional.
PDF (SAPI v7.4, Page 23-24, #32)
GET /sapi/v1/c2c/paymentMethod/getPayMethodByUserId
X-MBX-APIKEY: <key>
timestamp=...&signature=...
AutoP2P production (line 2980)
POST /sapi/v1/c2c/user/getPayMethodByUserId
X-MBX-APIKEY: <key>
timestamp=...&signature=...
Recommendation: use the AutoP2P path (/user/getPayMethodByUserId POST) as it is validated in production. The PDF path may also work as a fallback.
