Notifications seen as duplicate on Twitter

[jouir]

When a product is available, a notification is sent to Twitter. When the product is sold out, the reference in the database is deleted and, eventually, a reply to the original message is sent.

Sometimes, the very same product is available again. A new notification, with the same message content, is sent. But Twitter returns the following error:

failed to create new twitter thread: twitter: 187 Status is a duplicate.

I don't see a way to check if a status is a duplicate before sending a tweet on the Twitter API.

We should create a checksum of the status content, store it in the database with the twitter ID then verify the checksum before creating a new tweet. If the checksum is detected in the database, reply to the original tweet or the reply to continue the thread (unless enable_replies is set to false).
