Update Service Strategy

Request parameters

Required: id (strategy ID)
The remaining fields follow "Add FX strategy". See each field's definition for its format, value range, default behavior, and business meaning.

Business notes

id identifies the FX strategy to edit; the remaining fields (service strategy, channel, supported currency pairs, service time, FX mode, spread-bearing method, etc.) have the same meaning as in the create endpoint.

Risk warning

This operation changes an FX strategy configuration and may affect the FX service that takes effect for customers under that strategy. Confirm the target strategy and parameters before calling.

Result

On success the FX strategy is updated; see the 200 response definition for the returned content.
