To generate a JWT you need to call the ingresso F13 jwt endpoint.F13 JWTs expire after 24 hours.
1.
Use your backend server to contact the F13 endpoint, this ensures secret keys are hidden.
2.
Make a POST call to the F13 environment you're working with i.e. https://dogbex.ingresso.co.uk/f13/jwt.v1
using your base64 encoded credentials in the Authorization
header.
3.
Take the access_token
thats returned in the call and add it to the application apiAuthToken
property. You need to configure this when you create the application. See the getting started guide for an exmaple. Example in Node.js#
