Send Fulfillment Email

POST 
/api/walmart/:integrationInstance/wfs/inbound-shipments/:shipment/fulfillment/email

Send the operator-composed portal invite to the resolved 3PL/supplier recipient (a 3PL warehouse's address email, or the supplier's PO email), substituting the {{reference}}/{{portal_link}}/{{instructions}} tokens server-side, then flip the packet status to Sent (sets sent_at). The recipient is resolved server-side — it is not accepted from the request. Returns 422 if no packet has been built, or if no recipient email is configured for the source (add one to the 3PL warehouse address / supplier before emailing).

Authorization

Any valid API token can call this endpoint — no specific scope required. Manage tokens.

Authentication: Requires Bearer token.

Fields:

  • subject (string, required, max 255): the final subject line (tokens substituted server-side).
  • body (string, required): the final HTML body (tokens substituted server-side).
  • cc (string[], optional, nullable, each a valid email): additional CC recipients.
  • attach_prep_sheet (boolean, optional, default true): attach the prep & pack sheet CSV (unit mix, prep requirements, kitting) — included when the shipment has lines.
  • attach_receiving_label (boolean, optional, default false; the compose dialog pre-checks it whenever a receiving label is available): attach the WFS receiving label PDF, fetched live from Walmart at send time. Silently skipped if the shipment is a source placeholder or the live fetch fails.
  • attach_carrier_label (boolean, optional, default false; the compose dialog pre-checks it whenever a carrier is booked): attach the WFS carrier / pickup label PDF, fetched live from Walmart at send time. Silently skipped if no carrier is booked or the live fetch fails.
  • from_mode (string, optional, nullable, one of: merchant, system): sender-identity override. 'merchant' sends From the store's own domain (needs the SPF/DKIM setup in email_from_dns_setup); 'system' sends via SKU.io with the operator as Reply-To. Null = the tenant's default (email_from_default_mode).
