# renderContentTemplate

Render a content template against a contact: collapse [a|b] spintax and substitute merge fields: the CONTACT vocabulary updateWorkflowGraph lists ({{firstName}}, {{contactPropertyAddress}}, {{userFirstName}}, …), matched exactly and case-sensitively. Returns the rendered subject/body plus missingVariables: every token that did NOT render, whether it had no value for this contact or could not render at all because contactId was omitted (contact tokens then remain as literal {{...}} text AND are listed as missing). Inspect missingVariables (empty = fully rendered). Send with sendText / sendEmail (behind the organization’s send consent attestation). Pass spintaxSeed for a deterministic variant. Omitting contactId previews spintax and user tokens only: never send a no-contact render of a template with contact tokens.
