To switch from standard withdrawals to instant withdrawals:
1

Contact CryptoProcessing support team

Ask CryptoProcessing support team to enable the feature for the currencies you need.
2

Replace the API endpoints

Replace /v2/withdrawal/crypto with one of these special API endpoints wherever you need to prioritize the processing speed:The requests for both API endpoints are similar to /v2/withdrawal/crypto, but some parameter names are different.For an instant withdrawal with conversion, only the currency you send to the address must support instant withdrawals.
3

Support additional callbacks

Instant withdrawals send the same withdrawal callback as standard withdrawals, with two additional values of its type field. Update the callback handler to support them:
  • withdrawal_instant
  • withdrawal_instant_exchange
To make sure you support all possible scenarios, use our integration test cases.
