Leadsquared restricts passing  SQL payloads,or xss payloads using LSQ APi  the reason being that Leadsqured firewall stops those using web firewall before reaching to backend/api.

Ex; cannot pass  "sleep(200):" in the payload, as leadsquared firewall identifies it as a SQL query.

**Please find below screenshot of the response and payload **
