The Replit developer api has been suspended.

documentation remains only for posterity

So you want to use the Repl.it api?

It's pretty rough, but here's what we got for ya so far. Please keep in mind this is in early alpha, things are subject to break and docs are incomplete.

• overview of how the protocol works: /protov2 (contains some internals you can ignore -_-)
• all the services and how to interact with them: /services
• there's a js client library
  • with some bare bones docs
  • the source is over here
• the protocol uses protobufs, here's the source
• looking for an api key? go here

Once you have a developer key, you can start issuing tokens and connect to existing repls. Each time you connect you will need to your your API key to get a one-time token for a specific repl.

Here is the endpoint for getting a token

• Method: POST
• Url: /api/v0/repls/<id>/token where id is the repl's id.
• Body: needs to contain apiKey (this is the key @turbio gave you)
• Response: the response will be the token as a string

Once you get the token, you can use it in to connect to the backend, in crosis it looks like this client.connect({ token: myToken })

Here's a simple example running the command echo hello world inside the repl. You can fork it and add your API key.
