If you uses COM APIs for use in custom applications, you can use DEX2 to retrieve this information. The example is in Fundamental and Reference Data example.

Asset Class : .STOXX50

Fields List: TR.IndexConstituentName;TR.IndexConstituentWeightPercent

The result is:

If you use a different API, please provide me a link to that API.

Thank you, this is helpful.

Is it possible to extract similar data for a custom index/portfolio that I have created in the PORT tool?

The formula builder found my index, but the TR.IndexConstituent fields return null.

You can use field names from the Portfolio category in the Formula Builder, e.g. TR.PortfolioConstituentName, TR.PortfolioShares, TR.PortfolioWeight.
