Currently, you may encounter the media-download-error when sending WhatsApp messages with attachments via the API. This error occurs when WhatsApp is unable to download the attachment from your server.

We are investigating this issue with WhatsApp and working on a resolution.

We migrated the edna Pulse knowledge base to a new engine and stopped updating the documentation on this resource. Find all relevant information and updates on our new portal!
Open edna Pulse portal

Starting on November 1, 2025, the https://docs.edna.io/ resource will no longer be available. Please keep this in mind when working with the documentation. Until then, we recommend replacing all saved links and switching to the new portal.
