This is a developing situation and we will update this article if anything changes. 

As per Income Tax Department directives, Direct Tax TIN 2.0 APIs are disabled as of now. API services will only be extended to customers paying taxes directly for themselves; but cannot be extended to entities extending these services to their customers, i.e., Aggregators/ Service Providers/ Fintechs/ Banks – paying taxes on behalf of their customers.

We are currently working with the Income Tax department and Banking Partners to get this issue resolved and resume the services.
