Need Guidance on Updating Existing Mapping in Destination via Adobe Experience Platform API

[venkataak]

I have an existing destination setup in Adobe Experience Platform where audience data is being exported. I would like to update the existing field mapping (e.g., map a new schema attribute or modify the transformation logic) using the API, without recreating the destination or dataflow.

@venkataak Yes, you can update the field mapping for an existing destination in AEP without recreating the destination or dataflow, but there are a few limitations depending on the destination type and integration method. 

Use the Flow Service API to list your existing dataflows

Steps to approach it using API:

• Get the Dataflow ID
• Retrieve the Existing Flow Configuration
• Update the Mapping
• Validate the Changes

Considerations: 

• Recreation is not needed, but some destinations may not support real-time mapping changes. (verify that the platform updates are supported via API)
• You must preserve existing mapping structure if the destination expects specific fields.
• Make sure the schema changes are reflected in your dataset mapping.
