The decision was taken in a cabinet meeting chaired by Chief Minister Arvind Kejriwal at Delhi Secretariat.
The revamped anti-corruption helpline will help trap government employees who demand bribes.
"As per our promise, we have decided to launch anti-corruption helpline after around 15 days.
"We appeal to people if anyone is asked to pay a bribe by any official in Delhi, he or she should record it and give it to us through anti-corruption helpline. We will take strict action against him or her," Deputy Chief Minister Manish Sisodia told reporters here.

Sources in the government said that in the Cabinet meeting, VAT and other such issues were also discussed.
In its poll's manifesto, AAP had promised that Delhi will have the lowest VAT regime in India and will simplify other tax structures.
