Parts of the DSN
The Data Source Name (DSN) has the following parts:
{PROTOCOL}://{PUBLIC_KEY}:{SECRET_KEY}@{HOST}{PATH}/{PROJECT_ID}
See reference documentation: https://docs.sentry.io/product/sentry-basics/dsn-explainer/#the-parts-of-the-dsn
Not documented: if using oXXX.ingest.sentry.io the numbers following o are the ID of the organization.
DSN and Project Transfer
The DSN will remain the same during project transfer.
If the host in use includes oXXX.ingest - the numbers following o will need to change to match the new parent organization ID of the transferred project.
