WhatsApp Templates

Upload a media file

Upload an image, video, or document to Meta and receive a temporary media handle for a WhatsApp template header.

Use this endpoint only when you are creating a WhatsApp template with a media HEADER:

IMAGE header: upload an image with media_type=image
VIDEO header: upload a video with media_type=video
DOCUMENT header: upload a document with media_type=document

Do not use this endpoint for normal message attachments or campaign media uploads. If you want to send a WhatsApp campaign without managing template media handles, use the list/campaign workflow instead: create or import contacts into a list, attach the list to a WhatsApp campaign, upload or select the campaign media there, and send through the campaign.

How to use the returned handle:

Call POST /api/v1/whatsapp/templates/upload-media with multipart form data: waba_id, media_type, and file.
Read data.handle from the response.
Call POST /api/v1/whatsapp/templates and place that handle at components[i].example.header_handle[0] on the media HEADER component.

Example media HEADER component for the template-create request: set type to HEADER, set format to IMAGE, VIDEO, or DOCUMENT, and set example.header_handle to an array containing the returned handle.

Why this endpoint exists: Meta requires media used in template headers to be uploaded first through a resumable upload session. The template-create request accepts the returned handle, not the binary file.

Handle lifetime: the handle is short-lived. Create the template within about 24 hours after upload. If the handle expires, upload the file again and use the new handle.

Validation before upload:

image: JPEG or PNG, maximum 5 MB
video: MP4 or 3GPP, maximum 16 MB
document: PDF, plain text, Word, Excel, or PowerPoint formats, maximum 100 MB
media_type must match the file MIME type. For example, uploading a PDF with media_type=image returns 422.
