Create template

Changed on

Create a new message template. Supports two modes:

Custom template: Provide components with your own content. Submitted to Meta for review (can take up to 24h).

Library template: Provide library_template_name instead of components to use a pre-built template from Meta's template library. Library templates are pre-approved (no review wait). You can optionally customize parameters and buttons via library_template_body_inputs and library_template_button_inputs.

Request body

accountIdstring required

WhatsApp account ID

namestring required

Template name (lowercase, letters/numbers/underscores, must start with a letter)

category'AUTHENTICATION' | 'MARKETING' | 'UTILITY' required

Template category

languagestring required

Template language code (e.g., en_US)

parameter_format'POSITIONAL' | 'NAMED' | 'positional' | 'named'

Variable style: POSITIONAL ({{1}}, the default) or NAMED ({{customer_name}}). Named templates provide examples via body_text_named_params / header_text_named_params. Inferred as NAMED when omitted but a named-params example is present.

library_template_namestring

Name of a pre-built template from Meta's template library (e.g., "appointment_reminder", "auto_pay_reminder_1", "address_update"). When provided, the template is pre-approved by Meta with no review wait. Omit components when using this field.

library_template_body_inputsobject

Optional body customizations for library templates. Available options depend on the template (e.g., add_contact_number, add_learn_more_link, add_security_recommendation, add_track_package_link, code_expiration_minutes).

message_send_ttl_secondsinteger

Delivery validity window in seconds: a message not delivered within it is dropped. Range depends on category: AUTHENTICATION 30 to 900, UTILITY 30 to 43200 (12h), MARKETING 43200 to 2592000 (30 days); -1 (create only) keeps the 30-day default on AUTHENTICATION and UTILITY. Meta defaults to 600 for AUTHENTICATION and 30 days otherwise. If Meta later recategorises the template, it clears the TTL (read it back to check).
