API Compatibility Notice

If you use or plan to use Deal decimal values in Sell and your integrations use deals, your integrations may break after introducing new API. This is because the type of Deal value will change - decimal values will be sent as strings in JSON format, which will cause type incompatibility with current format. If decimal values are not used, they will be sent as integers as before.

Warning: If you currently use decimal values in Sell and your integrations use deals, they may cause the decimal part of values to be lost when updating a deal through the API.
