Facebook conversions API - does the customer information need to be lowercase?

Hi everyone! I’m having some issues with the Facebook Conversions API. Zapier is definitely sending events to FB, and FB is receiving them but the Facebook event manager says: “Event Match Quality: Poor” 😓


I’ve been trying to figure out why, as it looks like I’m sending the necessary information to FB. Reading through the conversions API documentation, I noticed two things in particular:

  • Hashing required - Zapier says they handle this
  • “Convert all characters to lowercase.” I’m not currently doing this on my Zapier action. Do I need to for the hash to be correct?
