Impulse API Updates (Jul 2022)

Impulse Backend Changes (Jul 2022)

This backend update introduces significant changes to the gateway. There are no changes to the HTTP API.

The official web client has been updated to accomodate these changes.

Gateway

Breaking changes

  • Gateway events have been reorganised
  • _SUCCESS and _ERROR events have been removed in favour of GatewayMessages' success property
  • Gateway error messages are no longer human readable; this should be handled client-side

Understanding Discord Tokens

Understanding Discord Tokens

There are two types of Discord tokens: normal tokens and MFA tokens.

Normal Tokens

Normal tokens can be split into 3 parts, each separated by a period/dot. The first part is the user ID string/snowflake in base64. The third part is the HMAC digest.

The second part is slightly more interesting. It is the timestamp at which the token was generated at, but depending on when the token was generated, you may have to add in an additional 1.1e9 to 1.3e9 to the retrieved timestamp to get the true timestamp.

Basic validations

If you want to verify if a token is real, but don't want to test token against Discord's servers, you can use the rules above (for the first and second parts) to filter out obvious fake tokens.
