E15003 — WhatsAppTemplateParameterMismatch
The message parameters do not match the parameters the template declares.
- HTTP status: 422
- Type: validation_error
- Name: WhatsAppTemplateParameterMismatch
What to do
The parameters you sent do not match what the template declares. Read the template you sent to, which names the version in service as live_version_id; read that version's language to see the placeholders it expects, with an example value for each. Send one parameters entry per placeholder, naming each one when the template declares named parameters.
