GoodTill API

Hello everyone,

I am doing a proof of concept for Automation Anywhere where I am trying to read data from a candidate EPoS system. However accessing the API requires the generation and reuse of an access token which is created using a POST statement passing three parameters - subdomain, username and password. The details of this can be found in the “Authentication - Create Token” section of the reference site:

Goodtill API (thegoodtill.com)

I have tried multiple areas to input these into the REST Web Services: POST method but I experience error consistently. I was wondering if someone could make a recommendation on the best way to do this?
