The “Try it” feature for this endpoint doesn’t work because it doesn’t double escapes newlines randomly for the siwe input. We recommend you try this in your terminal or a script.
Almost every API endpoint is authenticated using Bearer JWT tokens. In order to get the token, users sign an Otim-specific SIWE and submit the signature and siwe message to this endpoint. Here’s a script to fetch both the siwe and signature inputs:
