Two auth models:
  • API key — for creating checkout sessions
  • None — for session status, payment link info, and payment link session creation

​
API key

All keys use the ms_live_ prefix.
Never put your API key in frontend JS, mobile apps, or public repos. Backend only.
Authorization: Bearer ms_live_your_key_here

​
Example

curl -X POST https://merchant.minisend.xyz/api/merchant/checkout \
  -H "Authorization: Bearer ms_live_your_key_here" \
  -H "Content-Type: application/json" \
  -d '{"amount": 25.00, "description": "Order #4821"}'

​
Generate a key

  1. Open merchant.minisend.xyz/dashboard.
  2. Go to API Keys → New Key.
  3. Copy the full value immediately — it’s shown once. Minisend stores only a hash.
401 = invalid/missing key. 403 = key valid but merchant account inactive.

​
Rate limits

60 requests / minute / IP. Response includes X-RateLimit-Remaining. Exceeding it returns 429. Contact support for higher limits.
