API conventions

Request format#

Content-Type: application/x-www-form-urlencoded

All source-documented endpoints use POST forms. An example JSON block does not imply a JSON request body.

Orders and idempotency#

Keep merchant order identifiers unique. When the result is uncertain, query the original order instead of creating a payout with a new identifier.

Amount representation#

Use the currency unit required by the assigned channel. Do not multiply or divide by 100 without explicit instructions. Keep decimal places and the exact string unchanged between signing and submission.

Transport success vs business success#
