Cloudflare Leaked Credentials Check

Implemented new managed rule configuration of Cloudflare Leaked Credentials Check. Our API calls are getting intercepted by a 403 and what I perceive to be a challange to ensure we’re not bots. We are sending SON that contains html in the payload. Until we can further dissect the true cause I have disabled all rules and deployed. However we are still receiving the error. Has anyone else had this issue and can you assist?
