Custom Function Processing

Last updated: 2024-01-06 15:31:10

Overview
If the existing services or features of COS media processing cannot meet your needs, you can use the custom function processing feature of SCF to write core code logic in order to flexibly implement your business needs while reducing your development costs. For more information on SCF, see Overview.
Note: 
Currently, the custom function processing feature can only be initiated in a workflow.
Using SCF for custom processing will incur fees, which will be charged by SCF. For billing details, see Billing Overview.
