E15002 — WhatsAppTemplateNotFound

No WhatsApp template matches the requested slug.

HTTP status: 422
Type: validation_error
Name: WhatsAppTemplateNotFound

What to do

No template matches the slug you sent, or it has no approved version to send. List the available templates to find the exact slug, then send with that. For a built-in bird_ template this also answers a language it does not stock; a template you authored answers E15077 for that instead, and names the languages it can send.

Operations that resolve this:

List available message templates

E15xxx — WhatsApp sending & delivery: every code in this range
Errors: the full wire contract, status mapping, and error catalog
Error handling: branching on type and code, validation details, and vendor_code
