The MTA reversed course and began pushing out real-time transit alerts on Twitter after the social media company backpedaled on charging the transit agency big bucks for that service.

The transit authority began service alert tweets from its affiliated accounts again at 4 p.m. Thursday, MTA Acting Chief Customer Officer Shanifah Rieara said in a statement.

The MTA previously stopped using Twitter last Thursday when the Elon Musk-led social media site insisted the agency pay to use an integral feature that allows for such minute-by-minute posts.

“The MTA informed Twitter senior management that it would not pay to provide the public with critical service information,” Rieara said. “Twitter got the message and reversed its plan to charge the MTA more than half a million dollars per year for these alerts, so now no transit agency will need to pay.

“The MTA also received written assurances from Twitter that reliability on the platform will be guaranteed through technological means, so riders can count on receiving messages posted on Twitter.”

She noted there are other ways for riders to check on service alerts that were being more heavily used when “Twitter involuntarily interrupted the MTA’s access to its platform on April 27.”

The MTA stopped tweeting after the beleaguered social media platform approached the cash-strapped agency about paying $50,000 per month to maintain access to Twitter’s application programming interface – or API – system, an MTA official previously said.

The API system allows multiple computer applications to work together and when used by the MTA’s Twitter account, it produces status updates on the city’s subways and buses.

In a series of tweets Thursday, the MTA said customers can turn to @NYCTSubway, @NYCTBus, @LIRR, and @MetroNorth. It also said straphangers can still chat with the agency’s customer service teams.

 “We will continue to closely monitor to ensure Twitter meets the reliability standard riders deserve,” Rieara said Thursday.
