What is the API used for bulk tagging the data assets and please explain with an example

Hi @Dhanoordaran V
Please help me answer the below questions

1. Can you confirm which specific type of data assets you are working with (e.g., datasets, models)?
2. Which Azure services are involved in this scenario? Specifically, is Microsoft Purview being used in this context?
3. Would you need to tag multiple assets at once, or just one?
4. Are you already using the Azure CLI or Python SDK?

Hi @Anonymous

1. ADLS Gen 2 & Synapse analytics
2. Microsoft Purview
3. Yes , multiple assets
4. We are using POST MAN

We tried using "Label" api for this purpose and getting the below error:

Please note the GUID is correct, and User has data curator and collection admin role.

API used: /atlas/v2/entity/guid/{guid}/labels

Thanks @Anonymous for the inputs , anyhow we are looking for applying the labels not classifications (PFA image) in the query description.

And I think the solution you provided will apply the classifications on the Asset level and not the schema level. Please confirm if it's correct

@Dhanoordaran V

Yes, you're absolutely right,the /api/atlas/v2/entity/bulk/classification API applies classifications (tags) at the entity (asset) level, not at the schema element (like column) level, and not labels.
From your note and the attached image which references UI elements that show labels, not classifications, you're specifically looking to apply labels, which are a different metadata type used in Microsoft Purview, often for things like sensitivity labels, business labels, or governance purposes.
Microsoft does not currently offer a publicly supported API to apply sensitivity labels as shown in the Microsoft Purview UI to entities in bulk. The labeling experience in Purview is primarily UI-based or managed through Microsoft 365 Compliance Center for Microsoft Information Protection (MIP) labels

While direct API support for bulk application of sensitivity labels is lacking, you can use classification APIs to achieve similar outcomes for governance purposes. Classifications can be applied programmatically to assets and schema elements, providing a way to tag and manage data assets effectively.
