Project settings
Project identity, keys, environments, data retention and deletion.
Keyslink
The project key identifies this project to the SDKs. Client-side SDKs use the public identifier; build-time and server-to-server calls use the secret form. The secret half must never be shipped in an app binary or browser bundle.
Mobile apps use a separate credential pair (projectId plus appSecret) that signs short-lived tokens on device. See Mobile.
Rotating a key stops any client still using the old one from reporting. Roll it out to your builds before you rotate.
Environmentslink
Environments come from the events themselves. Listing them here is what lets you filter issues and scope alert rules to production.
Deleting a projectlink
Deletion removes the project and everything attached to it: issues, occurrences, logs, traces, uploaded symbols and stored artifacts. It is not reversible and it is not a way to reduce noise. Ignore issues instead.
