How many peers in fabric network need to endorse a transaction

Question

In a Hyperledger network, when a transaction happens, how many peers will have to endorse the transaction for it to be successful?

The number of peers required to endorse a transaction is not fixed. The number of peers required to endorse a transaction depends on the endorsement policy. The endorsement policy is specified at chaincode deployment time and is decided by the person who sets the policy.
