Do I need a paid Zapier plan to use the BytePhase Zapier integration?

BytePhase does not charge separately for the Zapier integration; your Zapier plan is billed by Zapier under its own rules. Two things depend on that plan: how often Zapier checks BytePhase for new records, and access to Webhooks by Zapier, which Zapier lists as a premium feature. You only need Webhooks by Zapier if you post to BytePhase directly instead of using the BytePhase app’s steps.
