Z-PROInstall

Summary

Send a file with an optional accompanying text message to a WhatsApp group using the Z-PRO API via a multipart/form-data request.

Inputs

• Input Binary Field (required) — Name of the n8n binary field containing the file to send as the 'media' form-data field.
• Body — Optional text message to accompany the file.
• Number — WhatsApp group ID to which the file and message will be sent.
• External Key — Unique external key generated by your system to identify and control the message sending.
• Is Closed — Flag indicating whether the ticket should be closed after sending the message (boolean as string).

Output shape

a single response object from the Z-PRO API after sending the message file.

The output shape corresponds to the API response and depends on the backend service; no pagination or multiple items expected from this single operation.

Examples

Example 1: Send a file from the workflow's binary data field named 'data', with a message 'Test message 2', to a specified WhatsApp group ID.

Set 'Input Binary Field' to 'data', 'Body' to 'Mensagem de teste 2', 'Number' to the group ID string; set 'External Key' and 'Is Closed' optionally.
