FAQ

Questions about Send Media.

What does the Send Media action do in WhatsApp Business?

Sends an image, video, document, or audio file by URL through WhatsApp Business Cloud API. Per-type size and format limits apply; only allowed inside the 24-hour customer service window.

What inputs does Send Media require?

Required: Recipient phone, Media Type, Media URL. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if WhatsApp Business returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Send Media support batch operations?

Yes. Run Send Media inside a Loop node to process arrays. Tiny Command handles WhatsApp Business's rate limits automatically so you don't have to throttle manually.
