This is a plugin for Insomnia that allows the creation of JSON Web Tokens with Fireblocks method.
Install the insomnia-plugin-fireblocks plugin from Preferences > Plugins.
Add the fireblocks template tag as the bearer token and set the x-api-key as header and you are good to go.
The recommended way to set up is to create environment variable called bearerToken and set it up to be fireblock template tag, this way, you only have to set up the credentials once.
Insomnia allows you to import environments in multiple formats including OpenAPI, this way you can import the OpenAPI Specification and all API calls will be added to a new environment. Now on the top left, click OpenAPI env and click Manage Environments. There you can change the xApiKey environment with your API Key and change the bearerToken with fireblocks. There you will be prompted to fill your Secret Key PATH and API Key and you will be ready to make any call to the Fireblocks API
