@here we want to integrate our in-house Data quality tool with datahub ui is there any open api format for sending data to datahub like today great expectation does

hey Soumya! yes we support multiple different APIs in order to migrate data to datahub, hopefully one does what you're looking for. First, we have our open API which you might find the most useful: https://datahubproject.io/docs/api/openapi/openapi-usage-guide/#introduction-to-openapi---what-and-why and we also have our graphql API: https://datahubproject.io/docs/api/graphql/overview

Hi Chris thank you for the info is there a way i can directly update the metadata db which hold all the. info for datahub. (in our case it is a postgress db)

I wouldn't suggest directly editing the db although you always could using something like pgadmin. But the risk is that you could change something in the DB that doesn't get updated in your graph store or elasticsearch indices, therefore potentially breaking something. So using an API to update data is definitely the recommended approach
