OAuth
The MAST OAuth service allows authorized 3rd party applications to make requests against MAST APIs on a user’s behalf. If you are a developer who wants to integrate your application with MAST using OAuth, please contact us at archive@stsci.edu.
If you are a user who needs a token for programmatic access to MAST APIs, including data download, view the instructions for creating a token at https://auth.mast.stsci.edu/.
