Summary

We'd like to introduce the newest release, which focuses primarily on fees topic! 💰💰💰

Check-out new FEE GUIDE here! Everything you need to know about configuring merchant fees in one single page!

Two basic changes can be noted:

• The maximum limit for "fee_op_type": "subtract" has been added, from now, the fee value can't be higher than the Unblock fee value.

Limitation should match all configs that match with your fee configs - input_currency, output_currency, direction. If there is no config specified, the maximum limitation will be reflected to the all ones.

When you will try to set up amount higher then the maximum limit, you should receive 400 status code saying: Value exceeds the maximum limit for the subtracted fee.

• The usage of "fee_op_type": "subtract" from this release is disabled for all merchants. To start using it, you need to contact with Unblock operation team.

This release will go into the production environment on Wednesday, 24th July 2024.
