Look up a library template

Look up a single pre-approved Template Library template by its exact name, to introspect its structure before importing it. Most importantly it returns the template's `buttons`: a library template with `URL` / `PHONE_NUMBER` buttons must be created with a matching `library_template_button_inputs` array (see Create Template), or Meta rejects it. Use this to discover which inputs to collect.

Update business profile

Update the WhatsApp Business profile. All fields are optional; only provided fields will be updated. Constraints: about max 139 chars, description max 512 chars, max 2 websites.
