How to subscribe from another platform?

I want to make another app connected to my meteor app.

this another app will stand alone and different app from existing meteor app. I need to consume or subscribe data from my existing meteor app.

how to do that?

thanks

Is the other app also running on Meteor ? If yes, there’s the DDP api available to connect to other Meteor servers and consume their data as you would with the relevant client. See https://docs.meteor.com/api/connections.html#DDP-connect

If it’s not running on Meteor, 2 choices: either you add a DDP package to have your client be able to connect to the server, or you build your own API with HTTP on the server, and consume it from the client as you would with any kind of server.

Seeing you need subscriptions though, you’ll most likely want to go through DDP.

thanks @pdecrat let me try use ddp from other app. this app not meteor app
